"USB device not recognized has malfunctioned"
does this only happen with the one device and not the other? if so, strange, but if had this message before on a usb wi-fi dongle which the computers has drivers for and recognises and heres the only way to fix it:
shut down the PC. unplug the power cable from the wall socket for about a minute, (holding down the on button while cable is out may also help), plug back in and boot up.
from what Ive read, the motherboard stores the electricity, and sometimes can block things like USB, unpluggin the power cable and holding the power button sorta "resets" it, i.e. drains the power and restores normal function.
