Subject: "i2c_hid: Could not register for interrupt, irq = -1" on Thinkpad Tablet 10
Date: Sat, 31 Jan 2015 23:01:17 +0800	[thread overview]
Message-ID: <54CCEE3D.9040306@m-labs.hk> (raw)

Hi,

among the many problems that the Baytrail-based Thinkpad Tablet 10 has 
under Linux, the built-in Wacom digitizer does not work. I get the 
following messages in the kernel log (with i2c_hid.debug=1):

[  593.224249] i2c_hid i2c-WCOM0008:00: Fetching the HID descriptor
[  593.224259] i2c_hid i2c-WCOM0008:00: __i2c_hid_command: cmd=01 00
[  593.243080] i2c_hid i2c-WCOM0008:00: HID Descriptor: 1e 00 00 01 ee 
00 02 00 03 00 0a 00 00 00 00 00 04 00 05 00 6a 05 14 01 02 03 00 00 00 00
[  593.243110] i2c_hid i2c-WCOM0008:00: Could not register for 
WCOM0008:00 interrupt, irq = -1, ret = -22
[  593.253422] i2c_hid: probe of i2c-WCOM0008:00 failed with error -22

What should I look at?

Sebastien
