9600 indicates it's not one of the tablets we support, that's for sure. I think the old Intuos 1 and 2 had 9600 baud, so _maybe_ it's one of them. the format with the highest bit set in byte 1 but not in the others is similar to ISDV4. the button flags in the first byte are a different layout though. so it's similar to some extent, but definitely not the protocol we currently support.
