Max Ward Posted October 6, 2013 Report Share Posted October 6, 2013 Hey team, Have been trying to access my PnP Link G4 V5-6 WRX ECU for about a day now. So i had PCLink 4.9.8 installed and all the drivers installed correctly then when i went to plug the G4 in I get: USB Device not recognized Windows has stopped this device because it has reported problems. (Code 43) When i look at Device Manager i can see there is a little mark next to it and it says Unknown Device. So talked to a few guys on ClubSubNZ forum and they reckoned that the ECU firmware was not matching PCLink so I have now just gone through the whole list of PCLink downloads and it is still doing the same thing? Every download i tried installed the drivers fine and i was removing them correctly after each install. Checked the ECU, it has the COM cable plugged into the USB port. I am starting to think it may be a problem with the cable or the USB chip.. or the previous tuner has gone and locked the ECU. Note that i am doing this all from a workbench (Not connected to car power) G4TB PCB Rev 1.2 Serial# 4395 Any help is much appreciated. Thanks, Max Quote Link to comment Share on other sites More sharing options...
