Hi, I am running current, and I just tried installing this for my i2c trackpad:

github.com

GitHub - wulf7/iichid: Generic HID layer for FreeBSD. Including I2C and USB backends.

Generic HID layer for FreeBSD. Including I2C and USB backends. - wulf7/iichid
github.com github.com

the driver compiled and loaded from kld_list in rc.conf.

I see the following output in dmesg:

This leads me to believe, perhaps incorrectly, that devices hms2 and hmt0 were registered for my trackpad.

However, I cannot find any device nodes corresponding to these devices.

For /dev/ums* there is only /dev/ums0 which is my wired mouse.

None of the /dev/input/* devices correspond to my trackpad either.

I have devd installed and running.

Apologies if I'm doing something stupid, I am very new to FreeBSD.

With the current iichid version you will not find any device nodes except /dev/input/eventX, so now the driver works with X server only.
Since you don't see them at all, I would suggest opening an issue on the project page and submitting your dmesg() output there.
