I am trying to connect my nanoKenbak to a Raspberry Pi USB port so I can upload/download programs. When I attach the nano to a USB port on the Pi, it doesn't seem to show up as a USB device on the Pi. (Nothing in the kernel messages or syslog)

Has anyone done this, and if so, what do I need to do differently?

The nanoKenbak-1 does not have a UART. I know Frank Prindle hacked his and added an FTDI to connect to USB.

The USB on the nanoKenbak is for power only.

See my serial port here: https://groups.google.com/g/ukenbak-1/c/zbjJ5TWJfgU/m/q7ov0q1JBgAJ

Oh... I assumed it did since it 'tried' to send data when you do BitN+Display... The lights blink

How about the uKenbak-1? It also doesn't appear to connect to the Raspberry Pi. /dev/ttyACM0 doesn't appear and nothing shows up in the logs

Well, the uKenbak didn't work either. But that turned out to be a bad USB to UART module. Luckily, when I bought the replacement for the one I ruined, it came in a pack of two. The second one works fine!

That's because the ATMega328p chip does have a serial port, and the firmware writes to the serial port, but without the wires, the serial port pins are unattached.
