The linux-can mailing list (linux-can@vger.kernel.org) is the right place
to discuss such things.
Concerning the support for your device, as Pierre stated in the thread,
there are two families of Kvaser devices: "leaf" and "usbII".
Currently only the "leaf" family is supported by the driver in the kernel.
Pierre did a copy of kvaser_usb.c and adapted it to make it work with work
_only_ "usbII" devices. He sent the adapted driver as an attachment
(kvaser_usb2.c).
If you compare the two drivers (kvaser_usb2.c and kvaser_usb.c), you will
see that there are not a lot of differences between the two. I think
the best would be to adapt kvaser_usb.c to support both "leaf" and "usbII"
devices.
I've one such device at home but I have not had the time yet to have a look
at this... So if you want to adapt the driver, you're welcome :-)
Kind regards,

Olivier
