I have problem connecting Arduino Uno R4 Minima to Windows 7 host (IDE 1.8.10 and 1.8.19) - after connecting USB, CDC port driver fails to install ("failure of driver installation" window appears).
Code upload works, but anything related to serial port doesn't.
Connecting to Win10 machine is OK - everything installs correctly. Unfortunately, I don't have another Win7 machine to check if this problem can be replicated elsewhere.
System log contains information that installation of driver:
FileRepository\renesas.inf_amd64_neutral_b200538e73fc29f0\renesas.inf
for device
USB\VID_2341&PID_0069&MI_00\7&28FC284E&0&0000
returned 0xe0000219

@JwX000 for some reason your machine is enumerating the Minima as USB\VID_2341&PID_0069&MI_00 while the driver looks for USB\VID_2341&PID_0069&MI_02 (which works on Win10+) . Probably forcing the driver (either via zadig or directly in windows) would work; in the meantime @per1234 I would mark Win7 as unsupported

Thanks for the clarification @facchinm. This means it is a documentation task so I have transferred the issue to the arduino/docs-content repository.

Hello!
It may be some local configuration problem - after opening zadig there was already another mapping for USB\VID_2341&PID_0069&MI_02 (into WinUSB driver) - didn't notice this at first, remapped MI_00, got detected but unusable port (serial monitor cannot set parameters), then found MI_02, remapped it and it seems to work (using AnalogReadSerial example)
Should I close this ticket or is it waiting for documentation update?
