Firmware update issue - USB install
I had a problem to install new firmware via USB (avrdude error) - COM5 port was listed, but I could not get a communication with the printer. First I reinstall the driver, no help.
I had to change (force) the COM port number in windows device manager. Easy fix, if you know what to look for.
