hp mini 110 unknown usb device

[lanken123]

i had this netwook ofr ahile and have run into a serious problem. basically the netbook refuses to recognize any mass storage device( phone, usb stick, zune) but can regonize usb devices such as a logitech reciever for wireless mice and keyboard. i tried uninstalling the unknown device under device manger and reconneccting it but that didnt work.

any ideas?
