Failed to forward mouse event: Failed to write to HID interface #892

Closed void4main closed 2 years ago

void4main commented 2 years ago

Hi all, not sure what's wrong or how to debug this:

Description

Keyboard and mouse do not work.

Both devices are present /dev/hidg0 /dev/hidg1

USB-A cable male-male connects the Tinypilot (rpi4) either to a Raspberry Pi 3 or Jetson Nano. Both do not work. I have no problems with the webinterface nor video. Powersupply is 3A and no errors in the logs.

Thanks for reporting this!

Are you connecting to the Pi's USB-C port or one of the USB-A ports?

void4main commented 2 years ago

Thank you!

Only the USB-A ports for the connection (only power is over USB-C on the Tinypilot)

mtlynch commented 2 years ago

Oh, the USB-C port is the only one capable of emulating USB devices, so you need to connect to that port. See this tutorial for details:
