Hello Bernd,

many thanks - especially for the flash description above!

Two remarks to your dfu for Linux description:

change "./configure.sh" to "./configure"

A proper patch for removing the vendor check is attached, so that you can
link the patch in your description.

It should appear in this posting e.g. at http://marc.info/?l=linux-can like
the attachment from Gediminas:
http://marc.info/?l=linux-can&m=139036935703648&w=1

here: http://marc.info/?l=linux-can&m=139036935703648&q=p3

Btw. I was not able to update my adapter because it fails at different
percentages of the download - see below. I'll try with another usblib or
another Linux box.

Best regards,
Oliver
