Hi, I have a new Tong Fang GK5CN5Z (branded as PC Specialist Recoil II) laptop, and as far as I can tell the touchpad is currently unsupported. I'm running 4.17.13-gentoo with everything mouse-, synaptics- and I2C-related turned on under input device drivers, and I've enabled the 'mouse', 'evdev', 'libinput' and 'synaptics' X input drivers. I don't see any devices under `xinput` other than my external mouse and XTEST. I'm not really sure what I should be looking for beyond this or how to get started, as I've never had an issue with non-working input devices before. Can anyone point me at how to start diagnosing this? If it's of any help as a starting point, here's the output of `dmesg | egrep -i '(hid|input|i2c)'`: [ 4.390953] input: Sleep Button as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0E:00/input/input0 [ 4.391029] input: Power Button as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0C:00/input/input1 [ 4.391960] input: Lid Switch as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0D:00/input/input2 [ 4.392942] input: Power Button as /devices/LNXSYSTM:00/LNXPWRBN:00/input/input3 [ 4.488695] input: PC Speaker as /devices/platform/pcspkr/input/input5 [ 4.497663] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input4 [ 4.502613] hidraw: raw HID events driver (C) Jiri Kosina [ 4.516159] snd_hda_codec_generic hdaudioC0D0: inputs: [ 4.525327] input: HDA Intel PCH Mic as /devices/pci0000:00/0000:00:1f.3/sound/card0/input6 [ 4.525927] input: HDA Intel PCH Headphone as /devices/pci0000:00/0000:00:1f.3/sound/card0/input7 [ 6.432527] usbhid 1-6:1.0: couldn't find an input interrupt endpoint [ 6.434469] hid-generic 0003:048D:CE00.0001: hiddev96,hidraw0: USB HID v1.10 Device [ITE Tech.
