Hello !
I have the same problem on a Ling More G3 .
I was trying to make modifications to the fuel map, and my computer crashed .
Since then, when I plug the USB cable my PC crashes.
I tried another PC and another USB cable, but it is similar.
My device manager I have an unrecognized USB device.
Would you have a solution?
Thank you !
Sorry for my bad English, I'm French !
