Hi David,

Did you already try sysutils/iichid on 12? (its functionality was merged into 13 not too long ago).

Cheers,

Turns out that the touchpad on the Precision 7520 (and likely several
other "newer" (last few years) laptops uses I2C.

For stable/12, I had built/installed the sysutils/iichid port;
iichid is part of base FreeBSD in stable/13 and head. And while
the mouse works (under X11 -- not on a vty) in stable/13 & head;
it still does not work under stable/12.

I had appended:

hw.usb.usbhid.enable=1
iichid_load="YES"

to /boot/loader.conf for each of stable/12, stable/13, and head. For
the latter two, I see several additional kernle modules brought in (such
as hms.ko, hidmap.ko, and hkbd.ko); I don't see them either in base
stable/12 or in ports (though I may not know where to look).

But it's progress!
