Issues hooking up a USB/Zigbee device

I have a USB FunkStick (Silicon Labs BV2010/10), which it says has
support in uslcom since January, I'm on 12.1-RELEASE-p6 so that should
be covered.   It shows up on `ugen5.3` if I check `usbconfig` which is
what I'd expect.  I think I should have some `/dev/cuaU` and
`/dev/ttyU` devices so that I can point OpenHab at - but I'm not
seeing them.

I've added the following tweaks to loader.conf that I think cover what
I need:-

    usb_template_load="YES"
    hw.usb.template=3
    umodem_load="YES"
    ucom_load="YES"
    uslcom_load="YES"

I'm new to this end of BSD so if my noobs are showing then feel free
to point them in the direction of the right docs.  I'm not scared of a
little RTFM time.

You should be able to use `usbconfig dump_device_desc` to show the
device identifiers. The idVendor and idProduct shown should match what
the driver is expecting.  It may be a bit tricky as you have to expand
the vendor/product tables from here
https://svnweb.freebsd.org/base/release/12.1.0/sys/dev/usb/usbdevs,
but this is the list of devices the driver will attach to https://svnw
eb.freebsd.org/base/release/12.1.0/sys/dev/usb/serial/uslcom.c?revisio

Thanks, `usbconfig dump_device_desc` shows the identifiers

  `idVendor = 0x10c4`
   `idProduct = 0x8b34`

which tally up with the changes listed in
[bugzilla](https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=243494)
and included in revision
[357430](https://svnweb.freebsd.org/changeset/base/357430). The
revision is higher than the 354377 which you referenced, so does that
mean that I've misunderstood something in the build process and that
revision is not in the build I'm using (or need to build uslcom
myself, assuming I can do that without rebuilding the whole OS?)

Hello Motific,

I know it has been 2 months already but have you managed to solve
this? I am having exactly the same problem and can't sort it out.

The version info u/thompsa gave was the clue.  I'd wrongly assumed
that things like device IDs would be included without needing to wait
for the point-release.

I jumped over to 12-stable and it's recognised there.
