Hi @sisaha9, if you run /usr/doc/canlib/examples/listChannels do you get the same response?

Can you try uninstalling and then re-installing the kvaser-drivers-dkms via apt? Recently I've seen the kvaser dkms driver fail after what I suspect is a kernel update, it seems like the DKMS portion fails to rebuild itself properly after the kernel changes.

Reinstalling worked. Thanks!
