I/m new to FreeBSD (but not Unix in general) and I am setting up an embedded
server to acquire data from a weather station. The data comes from the weather
station console via the USB port on the server. The USB device is a Silicon
Labs CP2102 USB to UART Bridge Controller. Apparently this driver has been
added to FreeBSD 7.0-STABLE -
http://people.freebsd.org/~bmah/relnotes/7-STABLE/relnotes.html. I tried
installing the update, e.g. "freebsd-update -r 7.0-STABLE fetch", then
"freebsd-update -r 7.0-STABLE upgrade". Seemed to work. But I do not seem to
have the device driver loaded when I plug in the USB device. I get the
folowwing in the messages log:
Jun 10 16:48:02 wx kernel: ugen0: <Silicon Labs CP2102 USB to UART Bridge
Controller, class 0/0, rev 1.10/1.00, addr 2> on uhub0
But I don't see a device that I think I should see, like /dev/ttyU0. If I do a
"uname -a" I see the following:
FreeBSD wx.dennis-flynn.net 7.0-RELEASE FreeBSD 7.0-RELEASE #0: Sun Feb 24
19:59:52 UTC 2008 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/GENERIC i386
That doesn't seem right to me. Shouldn't I see something like 7.0-RELEASE-p1
or 7.0-STABLE? Did I do something wrong in my update to RELEASE? How do I
know if I'm running the STABLE kernel with the driver I want? How can I tell
if the driver (uslcom) is there and/or loaded?
Thanks in advance for all help.
