Hmmm, I guess I'll not be able to fully understand the ISD logic for these IDs for now. The code reads to me that if no serial ID is found then only enables support for pen.
Is it not instead that it shares same serial ID's as 0x92 series of tablets and you can only detect at query time if it also supports capacitive touch or not? Anyways, I'm about to send the patch but it will be lacking some it-would-be-nice-but-doesn't-hurt cleanups to wcmISDV4.c. Setting tablet_id for all cases but 0x9a and 0x9f case is now redundant as best I can tell. Also of interest, it seems like the logic to set packet lengths in isdv4GetRanges()'s is duplicate of logic in wcmReadPacket() to set packet length. Since I've no way to test this code path, I'm reluctant to clean it up. I'll have to leave those two items for others.
