It would be better to have a new rule that matches Vendor name.
Section "InputClass"
Identifier "Wacom Vendor class"
MatchVendor "Wacom"
MatchDevicePath "/dev/input/event*"
Driver "wacom"
EndSection
For "wacom" USB kernel driver, the phrase "Wacom" is hard coded into
Product name in by driver and it ignores the Product field from HW.
If it came purely from USB, it would look just like your seeing. For
example, the Product value in USB Device Descriptor for my Bamboo
shows "CTH-670".
For "wacom_w801" serial touchscreen driver, "Wacom" is also hard
coding Product name in driver.
hid-wacom is doing the reasonable thing of letting the base HID logic
set the Vendor and Product values from HID report.
I think its safe to assume Vendor will always be "Wacom Co., Ltd" for
Wacoms since there are little options on were to get that info from
but that Product name may or may not contain phrase Wacom.
