Thanks, this works for ucycom.
I also just learned how to build the module only
thanks to the help from a list member:
cd /sys/modules/ucycom (or ugen); make; make install.
But as I said, ucycom is actually not what I wanted. I'd like to
use Silabs CP210x (which is only supported by 8-Current)
and generic cdc-acm.
For example, even if I load ucom and umodem, the generic
CDC device (LPC-P2148 example from http://jcwren.com/arm/)
still show up as ugen device.
[mcuee at freebsd7 ~]$ sudo kldload ucom
[mcuee at freebsd7 ~]$ sudo kldload umodem
[mcuee at freebsd7 ~]$ dmesg
ugen2: <LPCUSB USBSerial, class 2/0, rev 2.00/1.00, addr 3> on usb0
The same steps seem to work under NetBSD 4.0. The Silicon Labs
CP2101 device I have seems to work under NetBSD 4.0 as well.
But PICkit 2 and PICDEM FS USB demo work under FreeBSD 7.0-Release
and HPS USB stack Revision 711 but not NetBSD 4.0 (libusb related
problem). So I might want to try out the HPS stack with NetBSD 4.0
but I am too new to NetBSD.
