USB not recognized on Raspberry Pi 4 #20

anm8tor commented 5 years ago

I have Marlin 2.0bugfix firmware installed on a Raspberry Pi 4 , running Octopi 0.17. When I connect the Mini board to the Pi using a USB cable, the Pi doesn't register "seeing" the connection at all. Clearing dmesg after boot, but before connecting, then running dmesg after connecting produces nothing. Checking lsusb only shows the four ports. I can connect the Mini to my PC and communicate via Repetier Host just fine, so I have it narrowed down to a possible linux driver issue on the board, maybe? Or some settings in one of the files used to compile firmware.bin?

In theory, the two USB 2.0-compatible connectors would be the most like the Raspberry Pi 3B in behavior. I wonder if anyone has tried this with Raspbian Buster on the 3A+.

Anyone able to respond? BigTreeTech???

Pi 3b+ is fine for me. I've gone down the route of using the TFT pin 5 connector with TTL converter as it fits better in my Wanhao i3 plus clone. Have you confirmed it working on a PC? Is the have you got the shunt in the correct position for power on the board?

I have the same issue, Pi4B + SKR mini 1.1. Also tried setting over_voltage in rpi boot/config but it did not help. Other devices recognize the board, rpi4 doesnt, dmesg empty. Other usb devices work well with raspberry.
