What manufacturer are the thumb drives? I wonder if the manufacturer site would have drivers.

Try looking into updating the "chipset driver", or perhaps a reinstall of it.

USB 2.0 drivers will be included in the chipset package. USB 3.0 drivers will be a separate download and install package.

I would recommend that you remove your email address from the first post. It's never a good idea to post your email address on a public forum.

The thumb drive is from Kingston - data traveler 16MB

Three are from Kingston. I reformatted one of the Kingston drives still was not recognized
one from sandisk all fail to be recognized

Thumb drive is seen in Device manager.

Talked to Kingston Technical support. They said drivers are part of Win 7 OS.

Suggested I run computer repair from Win 7 CD . That did not repair anything.
Tried to do custom upgrade. Told that the installed OS was later version than on the OS on CD. Do I need to uninstall SP1 and all the updates??

No need to uninstall SP1 to do a repair install. You can download the relevant Win7 installation disc with SP1 integrated from

This may be too obvious, but I may as well post it anyway. Did you reboot? I almost never reboot my own laptop, just let it go into sleep mode and then wake it up. Turns out there is a Win7 bug which can sometimes prevent your USB ports from waking up. There is a registry change you can make to avoid this issue detailed in this MS technote : http://support.microsoft.com/kb/928631

It is for Vista, but applies to all Windows OS. Or you can just reboot to see if the USB ports are once again recognized.
