Touchpad on Tong Fang GK5CN5Z

Created attachment 277801 full dmesg output I have a Tong Fang GK5CN5 laptop, branded as a PC Specialist Recoil II. The device has an integrated touchpad, which, according to my reading is an i2c hid device. There was a problem that closely matched the symptoms of bug #199911, but it turns out that although the patch included there gets rid of some of my errors, the touchpad is still not showing up as a device. I'm still running the patch from that bug because I'm pretty sure it's solving a problem that I have. I'm not sure where to look next, but there are some errors that may be of interest: If I press the physical button that enables the touchpad, after disabling it, I see this in dmesg: [ 254.890450] i801_smbus 0000:00:1f.4: BIOS is accessing SMBus registers [ 254.890459] i801_smbus 0000:00:1f.4: Driver SMBus register access inhibited I am also seeing these errors from i2c_hid: > dmesg | fgrep i2c_hid [ 4.872189] i2c-core: driver [i2c_hid] registered [ 21.154505] i2c_hid i2c-UNIW0001:00: probe [ 26.229183] i2c_hid i2c-UNIW0001:00: failed to reset device.
