Ah, the MCP2551 SPI CAN controller. The linux kernel guys tend not to be very happy about it's performance/error handling, but it gets the job done and has a proper socketcan driver.
We've been very happy with the canable as well for debugging (semi truck CAN busses). It seems to just work, and is a USB CAN device with a socketcan driver as well.
Take some time at some point to read the manual at https://www.kernel.org/doc/Documenta...orking/can.txt
. It's surprisingly good, and will help you understand CAN bus debugging and what monitoring is available. candump and friends are also very helpful.
