USB ports stopped working correctly. Windows doesn’t get recognize anything plugged into USB ports but sees the device.
I have a Dell Inspiron 5160. I’ve had it for about 18 months now. Just after the year mark, my USB ports stopped working correctly. Devices I plug into is recognize that they’re plugged in, such as my PSP, and others, such as my cell phone with cable, get charge from the port, but Windows doesn’t get recognize anything is plugged in to install. I’ve tried installing all the different software that Dell recommends/suggests, such as Dell Support, chipset drivers, updated BIOS, Dell Notebook System Software, and Windows XP SP2, but nothing works. In device manager, I see that the USB host controllers and Root hubs are all there, but nothing will be acknowledged through them. Dell is of no help now, as I’m out of warranty. They direct me to their people in India. When they can understand what I’m saying, they claim outrageous prices just for troubleshooting. Most laptop repair places I’ve looked into don’t actually repair anything; they just help with wireless network setup, which I know how to do. I don’t want to ditch this laptop, but since I use it constantly for traveling, it’s not providing the productivity I need. Is there anything you can think of to help?
I think that you might have a problem with the system board. Here is what I would do in your case to troubleshoot the problem. I would boot from a Knoppix CD – live Linux CD. It will boot the laptop to a Windows like environment but it would be Linux. It’s pretty easy to navigate and you don’t need to know a lot about Linux for this test. You can download it here. Download an .iso file and burn it on a CD. Booting from a Linux CD will help to eliminate any Windows related problems, if you have any. After I boot to Linux, I would plug a USB flash memory drive into the laptop USB port. Usually Knoppix recognizes these types of USB devices without any problem and an icon that represents the USB drive will appear on the desktop. If Knoppix cannot see the USB device, then it’s likely that the USB controller on the motherboard is bad and Knoppix cannot see it. It’s not a perfect test, but at least something that you can try.
Just recently I had to fix a similar problem on Toshiba Satellite M45 laptop. It had 4 USB ports. When a USB device was plugged in, Windows saw the device but wasn’t able to recognize it. I had to replace the motherboard and it fixed the problem.

Hi,
I have a Vaio VGN-FJ170 with SP3 for XP. As of late, I’ve been having issues regarding usb 2.0 devices. In the past I was able to be detected and run devices at a slower rate, but now, 2.0 devices are completely undetected. I’ve bought a powered Belkin 2.0 hub and a 2-sloted PCMCIA device – both which were not detected. I had hoped that those devices would enable me to use my 2 gb memory stick and external hd – too bad. Oddly enough, the PCMCIA usb card I bought can still power my laptop fan when plugged in. Please advise!

I have a HP Pavilion dv4000 and for the past 3 weeks I have left my printer plugged into my laptop via usb port. Now my computer will not charge unless my printer is plugged into it. The printer doesn’t even have to be on, ust as long as its in my laptops usb port it will charge my computer. Doesn’t sound to bad,but the problem is the normal power cord that is suppose to charge laptops does not work at all. If I unplug it from the laptop it doesn’t dim the screen, but if I remove the printer usb cord the screen dims and the battery symbol shows up. However if I remove the charger while the printer usb cord is plugged into my computer then the screen will dim and the laptop will run on its battery. I have run virus scans and deleted a ton of my computer and nothing seems to fix this. Anyone have any ideas on how i can get my computer to charge normally? Thanks!

The Fozzy,
I would definitely run the memory test. Download Memtest86+ utility, burn it on a CD and boot your laptop from that CD. The memory test will start automatically. Run the test overnight, so it makes many passes.
If the memory fails, you’ll see a lot errors in red color. In this case remove an external memory stick (if you have any) and run the memory test again. Now you are testing the onboard memory – memory chips soldered on the motherboard.
If onboard memory fails, you’ll have to replace the motherboard.
I believe your Satellite Pro A60 (European model) is similar to Satellite A60 (USA model) witch has a few known problems. Read about these problems here.

hi, ive read all the comments above about usb devices causing toshiba laptops to freeze, my own problem is a little more complex lol, I own a Toshiba Satellite Pro A60 EN (EN? i cant find this anywhere online) the model number is PSA65E-00200UEN if thats any help, my problem is that when i bought the laptop (as a back up when my main pc crashed and dyed a hundred deaths in an hour lol) it had just been re-built, new hard drive etc and all new internal components, (or so the seller said lol anyway beside the point, i love it to bits and want it going again lol), i mean hard drive, cpu and a centrino processor, i got it homeand all was well, till i pluged in my ipod, which immediatly started charging, the dialog box in the bottom left showed up saying that the ipod had “malfuntione@ and i shud click it to see what the problem was, so i followed what i was asked to do, and the damned thing froze, so i re-booted, and tryed again, same thing happened, it eventually came to point where the laptop would let me login using password etc and immediatly freeze (whether usb device was plugged in or out) when my desktop pic appeared, i got my neighbour (who works for rank xerox) to take a look at it, so he completely re-built it again, using the original components it came with, everything went fine for the first few days and it just froze again randomly when i was online, i rebooted and i got about half throught the windows xp loading screen (the one just after u see all the ibos info at start up, b4 u log in) again when i froze yet again, (geting a bit of a habit by now i bet ur thinking lol) so i w8ed another few weeks as my own desktop pc was back in action (thank-fuly, i missed crimson skie’s, well ace game, anyway…) i tryed to boot it up about 12 times in a couple of hours, and everytime it froze at the same point, (i have not at anypoint after the second re-build used any usb devices as i thot that was the main cause), i called a company with a very, very high customer support service, and they recommended replacing the harddrive for a bigger 80 GIG model, which i did, then re-installed xp-pro sp1, i find sp2 has lots of bugs, and both my dad and myself use sp1 on our desktops without any probs at all, now the laptop has a far better proccessor than my desktop so i wud expect it to handle sp1 quite easily, its the 2.80ghz centino thats in my toshiba at the moment, is that standered kit for this model???? i dont know, im at my wits end with this thing now, but im reluctant to ditch it after the amount of cash i have already spent on it, so anyway to finish off my story lol, even after 3 re-installs, and 2 new hard drives, it still freeze’s when ever i turn it on, im now beginning to think it may be the motherboard, the main system board, or just an electrical fault with my usb hub’s, as far as i no they are the one’s that came with the laptop, as all 3 are the same colour and etc, and none of the plastic housing that holds them in place as damaged or scuffed so that sez 2 me they are standerd, one more tiny thing to chuck in at the end, when i tryed the remove battery and hold the power button trick, it froze FASTER! just as the windows xp loading screen apeared, not half through, lyk every other bleeding time lol, i also tryed to disable the usb ports in the ibos menu but it wudnt let me access the menu, it just jumped clear of the section, the laptop now freezes no matter what way u try to start it up, cd, dvd, safe mode with net. and comand promptand everytime the same thing, wudnt boot, so again sorry for the length of this but i felt i needed to fully explain my problem, thanks alot if you can help, and thanks alot anyway if you cant lol

Dear Laptop Freak,
For some time now I have been looking for a solution to a problem I have with the USB ports on my Toshiba Satellite A60 which has 3 USB ports (2 on the back and 1 on the side). Whenever I plug a device into the back 2 it says USB device not recognized, and when i plug it into the side USB port the device powers up but nothing happens in Windows. I have tried downloading a bios update but it won’t let me re-flash the bios as it says the bios is already up to date. I have also tried purchasing a PCMCIA USB card, but I get no joy from plugging devices into that either, and the drivers are installed correctly. Please help!!!!!

I have a HP laptop. When I plugged my cooling station into the USB port – unknown to me – I was allowed to plug it in upside down – my computer shut down after a while and that’s when i noticed the cooling station had been plugged in upside down. The top tab of the usb port is no longer visible (or missing) which is why it probably let me plug in upside down. Well the computer will not power on at all. Would the usb port cause the complete power failure? If so, will repairing the usb port resolve the power situation? Will all my data on my computer be lost? Is this expensive to fix? Did the usb port allowing me to plug in the cooling station incorrectly cause additional damage internally to my laptop?

Collins,
You can back up all personal information using these methods and after that reinstall the OS from scratch.

I have a Dell Latitude D510 Laptop. Devices such as sound (speakers), USB ports (4 if them), CD drive and network connection, symantec anti-virus, firewall are not working, printing,(disabled). Running the “msconfig” will display under services that these devices have been stopped. I do not know how to get them running. There is some very important information on this machine, which I am unable to save so that I can have the machine formatted. The machine is still able to connect to the internet and also receive email via outlook, but it wont show this under connection (LAN). What should I do?

Hi,
I have a Dell Inspiron 4150 laptop. The USB Port has come loose and does not work unless i keep it firmly jammed with my finger until I am finished with the USB device. Is there any way to replace the USB Port, or should I just resign to not using it whatsoever?
I also bought a USB card that I thought would solve my problem, but it still needs to be plugged both into the USB and Card port.
Please help.
Thank you

LF..
i got a problem. Its my PC. Ihave windows Xp Pro installed. when i install service pack 2, my cpu usage history in the task manager is always at 100% and the system process will be at 99. If i unistall the sp2 then its back to normal.
Also my USB dont detect anything. I tried reinstalled Windows and its still not working. There are no yellow Q marks in devicemanager but the USB device are shown as Unknown device or USB root hub. i installed the USB 2.0 drivers from the CD which came with the PC.
Processor…. AMD 64 bit
Motherboard… MSI rs480M
can u tell me whats wrong??
January 13th, 2008 at 11:34 am
vinAY,
This problem started just recently or it was like that from the time you bought the laptop?
Is it happening with one particular USB device or with many different devices?
I cannot tell you because it could be both software or hardware relate problem.
The first thing to do is find out if you have the latest BIOS installed. If not, reflash the laptop with the latest BIOS you can find on Dell website.
If your USB devices require some kind of special device drivers, make sure you have the latest drivers installed.
You can try reinstalling Windows. I know that’s a lot of work, but these way you can eliminate any OS related issue.
If updating the BIOS, reinstalling device driver and reinstalling Windows doesn’t help and you still have the same intermittent issue with blue screens, it’s possible that you have a hardware related issue. You’ll have to ship your laptop to Dell for service.
January 13th, 2008 at 11:19 am
Amanda,
Did USB ports work before you reinstalled Windows?
Did you reinstall drivers for these devices? Does your laptop detect devices at all when you plug them into the USB ports? Usually, when you plug a new USB device, a message pops up in the lower right corner and it says that new USB device has been detected. Can you see that?
Check the device manager and find out if you have something unusual (maybe a yellow exclamation mark) by the USB controller line.
You can access the device manager if you right click on My Computer icon on the desktop or in the start menu, then click Manage and click one more time on Device Manager.
Find out if you are running Windows XP Service Pack 2 (right click on My Computer and then click on Properties). If you have Service Pack 1, update it to Service Pack 2. Connect your laptop to the Internet and then run Windows Update Utility.

Hi my name is Vinay. I have a DELL INSPIRON 1501 which is 5 months old. I am experiencing some problems with the USB drive. When ever I connect an external device to my system, the laptop screen turns blue and I cannot work anylonger. I need to re boot once again. I had already expereinced more than 10 times now. I dont figure out where the problem is. Do you think it is the problem with the wndows OS? a couple of times even with out connecting any external device, i had experienced the same problem. But this happens very rarely.
can you please let me know what the problem is?
thanks and best wishes
vinay

Hi, my computer has been re-installed with all the drivers it came with XP Windows, i have a DELL Latitude 100L. But for some reason, now anything i plug into any of the 2 USB ports, be it my camera or ipod or printer, i go to My Computer and there isnt anything showing, would you know why?
I am not very tech minded with computers, so please can you reply in dummy form.
Many thanks
Amanda

Any new device that I plug into any one of the USB ports on my laptop is not recognised but any of my older devices I plug in are fine.
The computer works and the USB ports all work fine with some items. I have checked various leads e.g. my new ipod is not recognised but my wife’s is with the same lead in any USB slot.
Can anyone shed any light on why the new items are not recognised – someone has suggested they heard of the same problem with the SP2 update to XP. Anything plugged in prior to this update seems to work but anything ‘new’ since is not recognised.Has anyone heard of this before ??
Windows states I am up to date with the software (XP with SP 2 update) but there is obviously something wrong.
Anything anyone can offer would be helpful but please bear in mind I am very limited in my knowledge of computing so please try to make it as basic as possible.

WHEN i HAVE usb PORTS OCCUPIED MY tOSHIBA a200 DOES NOT REVERT TO SCREEN SAVER. Why?. When I remove connections to USB ports then it’s OK

I own a Toshiba satelite and the problem is if I insert any usb device my laptop freeze. Is it possible to fix this problem.
August 23rd, 2007 at 8:09 am
I have a desktop VAIO from Sony and suddenly my USB 2.0 devices stopped working, all the 1.1 devices are working correctly. I bought a PCI card with 4 2.0 USB ports and Windows says they’re there but nothing is recognized on them… 1.1 devices are still running. Is it the motherboard or a driver-related issue?
July 30th, 2007 at 11:33 am
I had the same “This USB device can perform faster if you connect it a High Speed USB 2.0 port.” Nothing seemed to fix it until I just tried Beckie’s advice of unplugging the computer for a minute or two. USB seems to be working correctly at hispeed now. Thanks!
July 28th, 2007 at 6:01 pm
i had the same problem, my usb ports quit working so i bought Dynex 2-Port USB 2.0 PCMCIA Notebook Card. it installed ok and solved my problem of non working usb ports but i have a new problem.burning a dvd was really slow.it normally takes about 10 minutes but now it takes like 25 minutes.does anybody have any ideas of why its so slow. the Dynex 2-Port USB 2.0 PCMCIA Notebook Card says its usb 2.0 so it should be about the same time.
July 22nd, 2007 at 10:52 pm
I have the exact same problem as Indi. Same notebook, same series and same situation ….pls help..!! or any shortage on the Acer Travelmate 4052.
May 6th, 2007 at 2:29 pm
I have Acer travelmate 4052 with Centrino processor, Intel 855 chipset. It was a bit slow even with 512 mb ram and heating as well. I serviced and cleaned the fan and it was fine again. Recently I bought a external hdd casing for desktop hdd which comes with an adaptor to power the casing, when I plugged the usb of casing to my labtop it worked well for about a hour or so then suddenly msg appears something like “Power surge on USB port…..”. I unplugged the usb from that port and reinserted it into another usb port of my laptop, again it worked for a while then again this power surge message. Now all three usb ports are not working or responding. If I connect my nokia phone, the phone shows that it is connected but my XP Pro doesnt. I tried reinstalling all the USB hubs and controller from the device manager but didnt help. Somebody told me that USB controller on the motherboard may be fried, some DBM chip, but I have seen my motherboard there is no Intel DBM chip, I thought of performing a clean install, but when I run the xp pro setup, my laptop freezes, sometimes at formating, sometimes at initial copying of files, and sometimes at final installation when it shows 35 mins left, I tried many times, sometimes after an interval of 12 hours and then it pushes to 5 mins left for setup to complete and then again it freezes.
Somehow, after about 50 tries I have successfully installed the xp pro and all the chipset drivers, latest, updated the BIOS as well, xp is with sp2, but system still freezes sometimes while booting, or sometimes after a while. Also compared to earlier time, it is taking a lot of time to boot, read things, to perform anytask, like opening IE, doc,etc. I have checked by replacing the HDD, ram replacement but to no use. Please help me I need these usb ports. My system is working but very slow and whenever I try to insert any usb device, it freezes. I can perform any repair myself, just help me to repair it. I cannot afford to replace the board as it is very costly almost equal to the price of my laptop. I tried the PCMCIA card with usb ports, initially it worked but now it is showing unknown device when I try to install my IDE to USB adaptor so that I can copy the data from my desktop hardisk to laptop, earlier mouse was working with pcmcia card usb port but now it is not working. Please help me. I was told by a technician that if USB controller is fried then howcome pcmcia card with usb ports will work as the controller is the same but only the interface has changed. I even tried to find the schematic for my motherboard but couldnt. Please help me.
Regards

I have Dell Latitude CPxJ. wheni try to use usb 2.0 hub, i get a message.
This USB device can perform faster if you connect it a High Speed USB 2.0 port.” When I click on that a message a window opens up saying: “There are no High speed usb hub controllers installed on this computer.The USB Storage Device is a HI-Speed USB Device and will function at reduced speed when plugged into a non-HI-SPEED port. You must add a HI-SPEED USB host controller to this computer to obtain maximum performance.” Do i need to install something.
March 3rd, 2007 at 3:01 pm
I found this solution a month or so ago when the same thing happened to me. Shutdown your PC. Unplug it. This apparently clears any residual power on the motherboard. Leave it disconnected for a few minutes. Reconnect everything, boot up your PC and your USB ports and devices should be working again! Let me know if it works for you. Good luck!
February 22nd, 2007 at 1:43 pm
I don’t know who sent this procedure, but it worked great!
