[QUESTION] ZB-GW04 USB VID + PID + unique description string?

[Hedda]

@xsp1989 Do you know if ZB-GW04 USB VID + PID? + does it have a unique description string written to EEPROM of USB chip?

USB VID + PID + unique description string is needed for automatic USB discovery in Home Assistant's ZHA integration:

PS: I don't have one myself but someone wrote ZB-GW04 v1.2 USB uses the identifier 1A86:7523 which should be VID and PID:

https://community.home-assistant.io/t/zigbee-coordinator-1a86-7523-cannot-start-or-pair-any-devices/545740

If that is correct then the question remains if it also has a unique description string written to EEPROM of USB chip or not?

PPS: 1A86:7523 is not unique so it will also need a custom description string written to EEPROM of USB chip for unique detection.

VID = 1A86 PID = 7523

@xsp1989 No custom USB description string written? ...I believe that only CH340B in the CH340 series features an EEPROM(?)

https://www.wch.cn/downloads/CH34xSerCfg_ZIP.html This tool can be used to modify the VID and PID of CH340 series, but GW04 has not been modified accordingly.

The model we use is CH340E, this chip does not support configuration

Software supports: CH340B, CH343P, CH342F, CH347T, CH344Q/L, CH348Q/L, CH9 101U/H/R/Y, CH9102F, CH9103M, CH9104L
