I upgraded my PC to Windows XP SP2. I have two flash drives (memorex & simpletech) - both 256 MB. And none of them appear in Explorer. In fact I get an error saying that there is a USB Power Surge on the Port, etc. I dont even see any of the devices in Device Manager. Surprisingly, I have other USB devices like Web Cam and Camera and they work perfectly. Even they give an error about USB Power Surge on the Port but they still work. So thats all the more confusing. I have tried all kinds of stuff like: 1) Uninstalled all USB Ports and installed drivers again 2) Installed the latest Chipset drivers from Intel 3) Rebooted the PC with the Drives inside, etc. I have applied all Windows Updates too. Please let me know of any other things to try. Appreciate any response.
