Describe your issue:
full error:
mcu ‘mcu’: Unable to open serial port: [Errno 5] could not open port /dev/serial/by-id/usb-Klipper_stm32g0b1xx_3E0012001150415833323520-if00: [Errno 5] Input/output error: ‘/dev/serial/by-id/usb-Klipper_stm32g0b1xx_3E0012001150415833323520-if00’
This happens on cold start of the co-processor, and on firmware restart. I am able to get everything connected with the following steps:
1:) unplug eddy probe
2:) send a RESTART command to klipperw
3:) re plug in the eddy probe a few seconds later
This method does not have a 100% success rate, and is quite annoying to have to do every time I change something.
The issue goes away completely when switching to a rpi4b running mainsailOS.
I have already checked that ModemManager is masked, and brltty.service does not exist.
I have no issue running the printer without the eddy probe on the thinkpad.
Does anyone have any idea what could be causing this?
