No com port appears. Tried removing xyzprinter software and reinstalling, but nothing changed, still doesn't recognize the printer. Tried linux Mint, but lsusb didn't show the printer either. Is it possible that I've fried the board during the reset process?? One other possibility I'm going to try. I have a serial port on my pc, and I'll use a serial to USB converter. Waiting on a USB gender bender...hurry up Amazon!
