hi, i recently bought a pc (used) and ive just tried plugging in a mp3 player into the usb and windows doesn’t see it, i then tried plugging in my camera and it doesn’t see that either. They are both getting power from the usb ports (I have tried all of them front and back). I’ve looked in device manager and all of the usb related drivers are all ok according to windows xp. i have an asus mn2pv-mx motherboard, have tried microsoft website, just wondered if anyone had any ideas should i delete the drivers and reinstall them? or is there something else you can suggest? thanks
