调研方向
Read can/interfaces/socketcan/socketcan.py around lines 589-602, starting with the socket.bind((channel,)) call and its surrounding error handling. Verify that binding failures retain the channel context in the OSError, then inspect nearby areas of the python-can codebase for similarly context-free Python errors and check that the resulting exceptions remain useful to client code.

描述
Is your feature request related to a problem? Please describe.
When you hit an OSError, unless you have debug log level tracing enabled your client code may wind up with a bare OSError with little context for what bus was responsible. When more than one bus is involved in your system you're left to disambiguate with some custom code of one's own.
Describe the solution you'd like
I'd like the OSError to have a note added to it with the necessary context to identify what bus channel was involved with the error. A perfect solution would be to augment the logic defined here

and replace it with
601c601,607
< sock.bind((channel,))
---
> try:
> sock.bind((channel,))
> except OSError as exc:
> exc_msg = f"Error binding socketcan bus at {channel=}"
> log.exception(exc_msg)
> exc.add_note(exc_msg)
> raise

Additional context
Consider any other areas of the python-can codebase that similarly raise naked python errors without context. Those should also benefit by injecting notes with the surrounding context that was being attempted.
