usb thermometer - TEMPer - FreeBSD

[Torfinn Ingolfsen]

Hello,

I got a new usb gadget, a TEMPer[1]. According to info on the net, this
thermometer is a I2C device hooked up to a usb serial chip[2, 3]. The
usb-to-serial chip is a WinChipHead 340 / 341, so that should work with
the uchcom[4] driver. There was discussion about MFC'in this driver to
RELENG_7 in february last year[5], but it doesn't seem to have happened.

I tried garbbing the uchcom driver files from cvsweb and compiling the
driver on my RELENG_7, but that didn't work. RELENG_7 as in
root at kg-work2# uname -a
FreeBSD kg-work2.kg4.no 7.1-STABLE FreeBSD 7.1-STABLE #4: Sun Feb  8
20:56:08 CET 2009     root at kg-work2.kg4.no:/usr/obj/usr/src/sys/SX270
i386


Any hints on how I can get this gadget working on FreeBSD?
