The result shows driver in upstream and 3.2.20 both work with > TPC2FG. I will ask Nils to test 3.5-rc2 or newer. For reference, he reproduced trouble (the driver rejecting his tablet) using 3.4.2 with the following patches on top: 9fee619505bd Input: wacom - add basic Intuos5 support f860e581fd47 Input: wacom - add Intuos5 Touch Ring/ExpressKey support 9b5b95dd516a Input: wacom - add Intuos5 Touch Ring LED support ae584ca47328 Input: wacom - add Intuos5 multitouch sensor support f393ee2b814e Input: wacom - retrieve maximum number of touch points 1963518b9b1b Input: wacom - add 0xE5 (MT device) support a882c932a628 Input: wacom - return proper error if usb_get_extra_descriptor() fails His machine is a Thinkpad x220t. The built-in tablet has USB id 056a:00e6. 3.4.2 without those patches works fine. (More details at [= 1].) I prefer to start with making sure mainline works well first, and then I'll be happy to work with you on backporting the current driver to 3.2-based kernels if you'd like.
