Hello, I have the same system (Lenovo ThinkPad X220 Tablet, model 4299W5Y) and probable the same problem.
The firmware loaded in the tablet gets garbled. I blacklisted the wacom module to load it manually. Begin test: root@vir:~/tablet# lsusb | grep Wacom Bus 002 Device 004: ID 056a:00e6 Wacom Co., Ltd root@vir:~/tablet# modprobe wacom root@vir:~/tablet# lsusb | grep Wacom Bus 002 Device 005: ID 056a:0094 Wacom Co., Ltd shutdown -r 0 ... reboot into windows Run fwdigi01.exe, the Digitizer Firmware Update Utility Ver.1.0.0.3, it shows: Current Version : ???? New Version : 013 P006 After a shutdown and boot, the firmware is back and the tablet works again. End test Regards, Bernard -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
