Description Marcel Holtmann 2014-09-12 17:34:18 UTC 
The i2c-hid driver tries to attache to a device, but fails:

[   12.330045] i2c_hid i2c-MSFT0002:00: Fetching the HID descriptor
[   12.330076] i2c_hid i2c-MSFT0002:00: __i2c_hid_command: cmd=20 00
[   12.330361] i2c_hid i2c-MSFT0002:00: hid_descr_cmd failed

Is there are I2C HID device that we enumerate that is actually not present or what is this intended for.

The device in question is platform/80860F41:06/i2c-1/i2c-MSFT0002:00 with firmware path \_SB_.I2C7.TPD1.

Interesting, somehow this was had escaped my notice. We do have a couple bugs opened for a list of ACPI errors, but as this one is very device specific, let's keep it as a separate bug. Thanks for reporting Marcel.

\_SB_.I2C7.TPD1 will be removed in the upcoming open source release which should be available next week.

Hi Marcel and Darren,

This device was just removed by our open source release. Could you verify it and close this bug?

Confirmed resolved in 0.74 release.
