USB doesn't show in My Computer

By kali79 ·
Hi all.
I was forced recently to reinstall my windows xp sp2 and I'm experiencing a problem with my usb devices.
What's happening is my usb memory sticks, external card reader and camera don't show in my computer. It shows in Device manager and shows everything is OK. I reinstalled the drives, signed different letters, but nothing helps.
My external hard drive and other usb devices which have their own source of power work just fine.
This is paint full 4 me as I can not transfer any files, photos etc.

Please HELP!!!
Thanks Jay

chipset drivers and install them for your computer. Reboot and likely everything will be available again.
Oh, for your camera, you may need to load the SW disk that came with it. However, usually one can just obtain a driver for the cam.

This doesn't make any sense

As the USB is working with Powered Devices but not with others.

My first thoughts when reading the Question was to install the USB Drivers but then I saw the bit about Powered USB Devices working.

Not sure what is going on here but if I was pushed I would be looking at some form of Corruption to Windows.

But without knowing how the reinstall was performed it's very hard to say much more than that.

maybe the powered devices are USB 1.1 and the nonpowered are USB 2.0 (or viceversa).

However, when devices fail, I first choose this option, re-install the chipset drivers. It works more often than not. Second, go into the BIOS and make sure that Legacy USB is 'Enabled'

After that, it can get a bit trickier, because it may just be that the power supply is not pushing power to the ports, is underpowered, or there is another problem.

But, I still stand by first installing the chipset drivers.

This may not work...

I have encountered a similar glitch with XP MCE which also included the optical drives. Microsoft has posted a solution:


This is a simple Registry edit, and it worked fine for me. Before you commence any Registry editing, export a copy of the Registry to a folder, and create a restore point in System Restore. That way, should disaster strike, you can import a working Registry configuration from the backup folder (or use System Restore to retrieve a working configuration.

Hope this helps. If you fix the glitch, please post back to this thread and let us know what worked for you.

I recommend a clean install of XP SP2, not just a repair install. If your installation CD gives you the option to reformat the HD, do this (format NTFS) before you reinstall the operating system.

Is there anything using

by shelli_2005 In reply to USB doesn't show in My C ...

drive D or E already? I have seen issues where the mem sticks or external drives insist on being one of those two drives and if the drive letter D or E was not available, I got exactly the same symptoms as you describe(device shows working properly in device mangler, but wont show up in My Computer)

Windows should re-assign an uncommitted drive letter

by nepenthe0 In reply to Is there anything using

I don't doubt the truth of your statement, but I cannot explain why this should occur. Can you?

Windows should assign the next uncommitted drive letter to new found hardware. The only time I have seen Kali's problem is a TweakUI setting that conceals the drive letter from the Explorer interface.

Perhaps Kali should check TweakUI if this is installed, and navigate:

My Computer > Drives

and be sure all drives are checked in TweakUI.
