thank you Bluerose!! i will try again. the other problem is that i bought this on e bay so i can't ask the dealer. should have bought from a store. actually it is attached to one of those rectangular ports with about 12 wires sticking up. i have several USB ports but only one of these others. however, i will try turning it on and off several times and straightening the wire. will let you know... and thanks again
