Description
After performing a FIRMWARE_RESTART, the can0 interface disappears. To restore it, I have to reflash the firmware on the lower machine.
In fact, my CB1 not only can't find can0, but the lower machine (M8Pv2.0) with the USB firmware I specifically flashed is completely missing. I can't even see the MCU of the lower machine with lsusb. I am a Chinese player, and I can't find a way to get help. Please forgive my broken English translated by Copilot。

Research direction
Start by reproducing FIRMWARE_RESTART on the CB1 and checking whether can0 and the M8Pv2.0 MCU appear before and after it. Use lsusb to verify whether the lower machine disappears; done means both the can0 interface and USB firmware device remain available without reflashing.
