After the error below, I've tried: 1) Deleting the 'installed' driver due to "Unknown USB device: Device Descriptor Request Failed". 2) Rebooting 3) Reinstalling driver from site yesterday: CH341SER.EXE 4) Plugging in GQ 390. (Boots with QG 380 message?)
>>>The same problem no matter how many times it's tried.<<<
Can someone please direct me to a solid driver or a clue as to why it's not installing even though it claims 'success' on CH341ser.exe?
I had this issue with Win7 and got around it by using 7zip: right click the .exe installer downloaded from GQelectronics and select 'unzip'. This extracted the contents of the executable to a folder where a setup.exe could then be run without problems. I think something was badly configured when creating the installer package.
