ok, ive got a trackball and ipac4 in my cab, but can only use 1 at a time. when i plug them both in i get a power hub fault and nothing works, i have to restart, i am now using a external powered hub which looks to fix the power prob, however. can only use one at a time. when they are both plugged in it says cant find driver for trackball(happ), should i unistall the normal mouse ? please help
thanks
