I have fixed the driver to handle the error reporting. Also thanks for your tip for generating bus-off by setting the host device at a different CAN bit rate! Below are logs with the updated driver. Let me know if you have any concerns, if not I will submit the v4 patch. berr-reporting on case: http://pastebin.com/qDRLERmW berr-reporting off case: http://pastebin.com/fUn3j7qU Thanks, Akshay
