Synaptics TouchPad disconnects on ThinkPad T14

Hi,

I am running stable/13 on ThinkPad T14 AMD laptop. Every few boots my touchpad gets disconnected. Rebooting brings it back.

Xorg.0.log just states "SynPS/2 Synaptics TouchPad: device removed" (see attached file). I have also attached dmesg.

I know this laptop is fairly new, that's why I run stable/13, to get modesetting driver through graphics/drm-devel-kmod.

I have dual-boot with Windows, problem is not present there, so it shouldn't be faulty hardware.

Is there anything I can do except to wait for a fix?

Try this:

Find this Touchpad device on the usbconfig(8) output.

Example output from my system:

Code: 
% usbconfig
ugen1.1: <0x1033 XHCI root HUB> at usbus1, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=SAVE (0mA)
ugen0.1: <Intel EHCI root HUB> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA)
ugen2.1: <Intel EHCI root HUB> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA)
ugen0.2: <vendor 0x8087 product 0x0024> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA)
ugen2.2: <vendor 0x8087 product 0x0024> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA)
ugen0.3: <Chicony Electronics Co., Ltd. Integrated Camera> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (200mA)
ugen0.4: <Logitech USB Receiver> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (98mA)

The lets assume your device is at ugen0.2 device.

Disable power saving for it:

Code: 
# usbconfig -d 0.2 power_on

Not sure that would help but worth a try ...
