lsmod | grep wacom

try to autogen driver input-wacom-0.11.1 from git, but fails with 

configure: WARNING: kernel version 3.0.0-13-generic-pae not supported

Anyone has a solution ?

Continued with sucessful make in 2.6.36 folder and copied wacom.ko to kernel

$ sudo insmod /lib/modules/3.0.0-13-generic-pae/kernel/drivers/input/tablet/wacom.ko
csschsu@omega:~$ dmesg | tail

looks fine ? But still empty system settings screen ( and wacom.ko is not loaded after reboot, been running depmod -a, and modules.dep is updated )

Tried to use wacom on a fresh installed 11.10 on another machine but same problem there.

Note from syslog when connecting wacom to USB ( indicate loading another module ?)

$ lsusb

is MTP the cause of missing detection, and if so what to do about it.

Wacom board is a Bamboo CTH-670 and it works ok on windows but I don't :-\

Removed libmtp-common and that clears the message in syslog but wacom table usb device is not detected and the wacom.ko kernel module is not loaded.

Best Answer

00df device isn't included in the list of supported devices in wacom_wac.c, check the the post:

Instructions in the post are a bit contradictory but I finally have the wacom tablet working after downloading wacom-bamboo.tar.gz and unzipping the contents into 2.6.36 in the latest gitcheckout of the input-wacom folder. Downloaded wacom-bamboo.tar.gz from

after build, move wacom.ko to the lib/modules/ folder.

wacom is now active, but a warning, there are more diffs between the wacom_wac.c code than just support for the usb device used. How to correctly merge the code changes is not obvious to me. Guess I'm up to new "happy" surprises.
