Comment 23 for bug 1884981

Interesting find indeed when doing
sudo modprobe -r i2c_hid
sudo modprobe i2c_hid
The "controller timed out" messages stops. Although that does not fix the touchpad it does suggest that this module is at cause.

After further digging, I got another set of log after booting on mainline (appended below). Basically, I see that the following shows up first before the "time out spamming" starts:

i2c_designware AMDI0010:00: i2c_dw_handle_tx_abort: lost arbitration
i2c_designware AMDI0010:00: controller timed out
i2c_hid i2c-MSFT0004:00: failed to retrieve report from device.

Now, I found these 3 exact log messages in this commit to fix another DELL Win8 touchpad in 2015:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.8-rc2&id=6d4f5440a3a2bb2e9d0d582bbf98234e9e9bb095

Maybe some learning from this commit can lead us to fix this for the MSFT touchpad.

Here my latest log on mainline:
