I am having the same issue. i install the wmodem driver then go into DIAG mode, ##3424# and it goes right in, but then I plug into computer and it says I am connecting a generic serial device and it cant find a driver for it. Since I dont know where the wmodemdriver is being installed I cant point to it. without that I cant even go into QPST and guess at a port to modify. Are there updated wmodem drivers? And for sure this wont work on a machine running Vista? I could have swore in your video you are running vista...thanks
