Retrieve it from the HID descriptor when it is available

Were you going to use touch_max for something (since its not referenced)?

Related to Bamboo's and pressure, does this happen to report 4 touches
on the newer Bamboo's that do not support pressure?  I haven't looked
at my 0xd1 Bamboo but I suspect  either contact count is not returned
or returns 2 (or maybe 3) contacts.

I'm hoping there is a way to detect differences in touch packet format
besides resorting to a quirks list.
