What exactly do you refer to from this thread?

???

Does can0 apprear in dmesg or in /proc/net/dev

??

Pls post the dmesg output of the relevant lines here.
And the lsusb output.

I'm still not the right person to ask these kind of questions - that's why I
tried to forward your request to Olivier (not Oliver) last time (see below in
this mail).

The only I know about the Kvaser driver and it's supported hardware is what
you can determine yourself from the Kvasers Kconfig section or the driver itself:

http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/drivers/net/can/usb/Kconfig?h=linux-3.14.y#n16

http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/drivers/net/can/usb/kvaser_usb.c?h=linux-3.14.y#n33

Regards,
Oliver
