A make and model would be nice, but my guess is that someone forgot USB or motherboard drivers. http://www.usbman.com notes this and more as well as XP not supporting USB 2.0 until SP1.
I have a new USB 2.0 Flash Drive Attache that if I connect to any XP PRO it works perfectly, but if connect to mine, it doesn't work, it ask for the drivers but it never can find them.
It's trying to look for "USB DISK 20X" drivers, but they are not on the hard disk.
I already deleted all the USB hard and restarted the PC, and when it restarts, it recognizes all the USB ports, but when I tried to connect the USB Flash the same hapen.
If you have an idea about what can I do in order to connect this USB to the PC would be very appreciated.
Regards & TIA for your help & support.
