Comment 52 for bug 1372609

So I took a stab at turning @Mathias's work into DKMS driver for Ubuntu 14.04, but I can't get past one issue.

You can see my work here (FYI, this is my first time mucking around with Linux drivers / Kernel stuff):
https://github.com/markmandel/psmouse-focaltech-dkms

But when I run `sudo dkms build -m psmouse -v focaltech-dkms`, I get the following error.
/var/lib/dkms/psmouse/focaltech-dkms/build/src/psmouse-base.c:473:36: error: ‘struct serio’ has no member named ‘firmware_id’
  if (!strncmp(psmouse->ps2dev.serio->firmware_id, "PNP:", 4))

Full version: https://gist.github.com/markmandel/40e92f7bf8b1c2ba4ffe

If anyone can provide me with any direction, that would be great. I'm wondering if the firmware_id member is not available in this driver version?
