Hey guys need help getting my phone to connect to PC in diag mode.

My phone will enter diag mode (thru the ##3424#) but my computer won't detect it as a port (in device manager)

I verified that it wasn't the USB cable or my drivers by connecting another phone in diag mode (s3)

Any assistance would be appreciated.

ps I tried the 9090 trick no luck
