@Emfdev: I am looking at two counters, a GMC-300E+ and a GMC-500+. Both have the CH340C chip as the USB-To-Serial converter, with VID:PID=0x1a86:0x7523.
As I am trying to improve on the device recognition in GeigerLog: do all GMC counter use this chip and can I thus see the vid:pid as a requirement for a GMC counter detection?
Hi ullix, sorry i didnt see your question. Yes we are using the CH340 chip so far with all GMC-300+ and 500+ devices. And just check with our latest one also has the VID:PID=0x1a86:0x7523
