... download devcon.exe from here: http://support.microsoft.com/kb/311272 ... extract the devcon.exe to C:\ ...(out of its folder) ... go to start run (type) cmd [press ENTER] (type) cd\ [ENTER] (....in the black box) ... then (type) devcon rescan [ENTER] ... which might re-activate your usb ports! . . .
