Ok this problem is driving me nuts. I recently upgraded to xp pro sp2 (from home). Before I used my ipod and flash disk on home (mass storage). After installing xp pro i found that it couldn't recognize them in explorer!!. Heres what i have tried and other info: I have installed the latest chipset drivers Tried removing all USB devices and rebooting Tried using other usb flash sticks all other usb devices DO work, just mass storage that doesnt Computer info: Windows xp pro sp2 Dell dimension 4600 All help will be much appreciated Info I can access the drive only through disk manager. I think its got something to do with windows not automatically assigning a drive letter on startup.
