Subject: Re: [PATCH 1/2] Alps HID I2C T4 device support

Hi Masaki,

Yes, I think I have a 044E:120C. Is there a way to find out for sure?
It's not listed by e.g. lspci.

The touchpad is definitely not reacting to anything. evemu-record does
not show any events either.

I have attached the dmesg output.

Best,
-Nikolaus
