Win7 : usb not recognized

July 22, 2014 at 22:01:40
Specs: Windows 7
I have an old Toshiba USB (it is only 1G, you can guess how old it is), it is not recognized by computer with Win7 OS. When I found another computer using WinXP, it is recognized and work normally. Then I try this USB in different computer, it is not recognized by all Win7/Win8 computer/notebook. I also try update driver in "device manager", it say drive is up-to-date and work properly.

If you get it working avoid putting anything too important on it because it might be showing signs of wear out.

Always pop back and let us know the outcome - thanks

Is that the only computer that doesn't recognise it now?

If so, do other flash drives get recognised on Win 7 computer?

Always pop back and let us know the outcome - thanks

So all XP computers see it but no windows 7 or 8 computers see it?

It doesn't seem like it would matter but the USB on the 7 and 8 computers will be at least 2.0. On the XP they may just be 1.1.

Is it just an external case with a drive added or did it come complete with the drive? If it was a complete unit what is the model number?

Does it use an external power supply or is it powered from the USB port?

Hi DAVEINCAPS,

It is just a USB Thumb, I forget the serial maybe Toshiba Transmemory.

My company's computer have two sets of USB ports, one set in blue colour and mention it is USB.3.0, another one is traditional ports (maybe 2.0). I plug the USB thumb to the ports not in blue colour. Did you mean USB 2.0 port not support USB 1.X device? My home WinXP PC support USB 2.0 and could recognized this USB thumb.

I feel Win7 always have problem in external device. I have another external HD, Win7 always have "write permission issue". For example, when I use "Word' and "save as" file to the external HD, it fail. But I would copy the c:\temp\aaa.docx to the same external HD in explorer. Any software execution access external HD have similar problem. Therefore, I change to use "USB Thumbs", although the memory size is much smaller.

Oh, ok, for some reason I just assumed it was a hard drive.

USB 2.0 should have no problem seeing a drive designed for the slower 1.1. I wouldn't think 3.0 would either. But it acts like a compatibility problem and that was the only possible difference between the computers that I could think of--older flash drive on newer USB. But still, as I mentioned, it doesn't seem likely.

Yes, I also feel it is old drive problem. Your guess is right, all XP computers is old and Win7 machine is new or it is 64-bit issue. The problem is why it is not compatible.

Besides, the reason I use the old USB thumbs is Win7 have many many problem when using external HD. When turn back to use USB thumbs, the warnings from Win7 is half.

Well I hope it's not a problem endemic to newer or 64-bit OS's. I didn't find any indication of that when googling the problem. For most people posting somewhat similar problems the drives would be working and then one day the OS stopped recognizing them, even though they were seen on other computers. In your case they never seemed to work on the newer computers.

Have you tried some newer flash drive to see how they work out?

Another fix I have seen a few times, Worth a try.

UNPLUG YOUR COMPUTER FROM THE POWER SUPPLY. Yes that’s it! Note that this does not mean just turning off your computer because modern computers don’t really turn off when you press the power button as the motherboard still gets power.

So first turn off your computer using Shut Down or pressing the power button and then UNPLUG it from the wall outlet. Let it sit for about a minute and then plug it back in.

Hi Johnw
Now I still scan the result of google, and I also add "HP" (my computer) in search. Until now the FixIt not help or FixIt report "we did not detect any problems and therefore no fixes were applied".
I have turn off the "USB Selective Suspend", but still not recognized.

Hi DAVEINCAPS,
I have some microSD or SD that used in phone/camera, they all recognized through card reader in Win7 computer.

Here is another variation of the power method.

1: When the power cord is unplugged, hit the power button a few times as if you are trying to turn on the computer.

2: Plug the power cord back in and turn the computer on.

Hi Johnw,

"Power Method" : Last time, I power off the computer, I already do so.

I made a summary :
The problem appears in my office PC. However, first time the USB thumb not work, I have tested this USB thumb in another laptop/PC (belong to colleagues), all are not recognized (Remind : all PC/laptop are Win7/Win8 in my company).
In past, I used this USB thumb to transfer files between old company's PC and home. Now, this USB thumb is still recognized in a PC and a notebook in my home. Old company's PC and my home's computers are XP.
All the solutions tried above only apply to my current office PC.

Open Device Manager, and remove everything under Universal Serial Bus controllers.

To remove them, double click on each of the entries under this category and choose Driver from the tabs up the top. There are several buttons under this tab, one of them is Uninstall. Click this button - it will warn you that you are about to remove the device from your system. Click OK, as this is what you want to do.

Repeat this with every entry under Universal Serial Bus controllers until they are all gone.

Reboot your system, and windows will detect the new hardware and re-install the drivers.

Do you not only uninstall my "Unknown Device", but uninstall all USB Hub?

However, I cannot uninstall them by single time. For example, when I uninstall "USB 3.0 Root Hub", then keyboard and mouse cannot be used again, therefore I cannot continuous uninstall others controllers.

Now I separate three times to uninstall all things under "USB controllers" once and let windows re-install each drivers. However, my USB thumbs is still not recognised.
