MAC M1 Pro Kvaser Leaf Light v2 Timeout error.

[dextertravispp]

I downloaded and built v0.3.1 and seem to be stuck with an interface timeout error. I get a similar error with the can_moni and can_test programs. Below is the result of kvl_test TEST INFO which i saw was the most informative from other posts/issues.

Any help appreciated.

Update. It appears this may be related to the particular Kvaser device. When i tried with a newer Kvaser of the same model it functions correctly with the both kvl_test and can_moni.

Is there possibly a minimum FW version we need from the Kvaser?

Comment: Yes, it looks like an issue with incompatible firmware.
