I have an AVR Programmer 2.1 and instaled pololu-usb-avr-programmer-win-121114.exe on WIndows 10.0.19042. USB AVR Programmer Configuration says “No Pololu USB AVR Programmer detected”. I can see “Pololu USB AVR Programmer v2.1” in the Device Manager under “Universal Serial Bus devices” and two new USB ports, although these are just “USB Serial Device” not as decribed in the documentation. I have tried uninstalling and reinstalling without the device connected and right-clicking the inf file and installing the driver that way. The mechanisn described in the documentation for updating the USB ports in section 3a of the documentation doesn’t work for me.
Can you help?
