I purchased a new USB drive just recently for my Dell Demension 2350 and it would not load. It loads on every other computer but mine. After spending an hour with tech support I returned it and exchanged it for a SanDisk Cruzer Mini: same problem, works for every computer but mine.
Whenever I plug it in it appears as an unknown device in the hardware manager and says it cannot locate a driver for it. I assumed there must be something wrong with my USB drivers as I shouldn't need drivers for a Flash Drive in Windows XP Home Edition. I uninstalled the drivers for my USB devices and attempted to reinstall them. First I tried to install them from my original CD and it could not install them because they were for Windows 95 or later. Next I tried downloading them from Intel for the chipset in my Dell and those would not install either. I noticed Microsoft had USB drivers availible for XP service pack 1 so I uninstalled service pack 2 and was actually able to re-install the original drivers. The problem is now NONE of my USB devices work- wireless network adaptor, turbo mouse, printer, ect. I moved my computer into the other room so I could connect it directly to my router and dug out my orignal mouse and desperately trying to get this thing working again.
So here I am, when I plug in my Flash drive it still comes up as an unknown device and now NONE of my USB devices are working. Any help would be greatly appreciated.
