help needed. XP don't recognize my usb anymore
about two months ago, I installed the base suite on my usb mp3 player (GenX 256MB USB 1.1 mp3 player). then I added the applications I wanted to use one by one. at first few days everything was ok altough apps. work a bit slow. but then when I plugged my usb, windows XP didn't recognize it. I think I had plugged it out while some apps. on it were still working. now it is useless. I have tried it in four different machines, (even on a mac!). I reinstalled its drivers from cd (there is no firmware update). nothing worked.
