Hi Azher,

The error which you are observing will occur if the inf file does not have the VID and PID present in the master file. I have checked the VID and PID in auomode master firmware. VID = 04B4,PID  = 2009. Please make sure they are present in the inf file. If not please add the VID and PID in the inf file and bind the device to this file.

Please try the above and check if you are seeing the same error.
