Description

I have a problem with a can bus card SB2209, the two red and green leds have gone off and klipper doesn't restart completely and remains waiting, I checked the power supply and everything is ok (the proximity sensor connected to the SB2209 has the led lit), I tried to remove power to the SB2209 and klipper tells me that it can no longer find the board, I tried to restart everything several times but nothing happened, I tried the reset button on the SB2209 but nothing. do you have ideas?

The report names the SB2209 CAN bus card and Klipper but provides no repository files, tests, logs, or entry points. Start by reproducing the failed restart and collecting the relevant Klipper and board status details; the issue is complete when the failure cause and a verified resolution are documented.
