V4L/DVB (4617): Problem with dibusb-mb.c USB IDs

There seems to be an off by one error in the dibusb-mb.c which causes
the "Artec T1 with AN2235" box to be detected as a totally different
box - but it only happens if the Artec is one with the correct USB
IDs. A patch is attached to the second post. However, even with this
patch, the box still won't tune. It will tune using a 2.6.12 kernel
though.
