That would help a lot. The working dmesg shows a line with: hid-generic 0018:0457:10FB.0002: input,hidraw1: I2C HID v1.00 Device [SIS0817:00 0457:10FB] on i2c-SIS0817:00 and then hid-multitouch 0018:0457:10FB.0002: input,hidraw1: I2C HID v1.00 Device [SIS0817:00 0457:10FB] on i2c-SIS0817:00 But these 2 lines do not appear on the 6.1.4 logs. So the device is not properly enumerated by ACPI or I2C. Hans might have an idea on how to debug/solve that issue. Also there were no changes between v5.15 and v5.16 in i2c-hid.ko, so it's unlikely to be an issue there (unless '5.16' means '5.16.x').
