[Ovmsdev] CAN bus logging not working

Wed Feb 8 07:53:15 HKT 2023

Ahh. Makes sense.

I guess one of these days I'll get around to actually installing my OVMS
properly.  I still get the occasional need to get at the device  (like for
fixing a reboot loop due to a botched  updated which requires physical USB
access).  For the moment it sits in the little space under the USB ports.
