Hi,
I wrote a simple port of the NetBSD ugensa(4) driver: USB generic

I would like for you to review the "ported" kernel module. The

Hi,
I added the defs for my Sierra 875, but the box panics up
when I connect to the port

The files are as follow:
- Modified kernel module for FreeBSD based on src/sys/dev/usb/uplcom.c
ugensa/ugensa.c
- Original NetBSD kernel module
ugensa/ugensa.c.orig
- Some header definitions while usbdevs is not updated
ugensa/ugensa.h
Unfortunally, I haven't been able to test this module since it
means that I have to buy one of the supported devices. It is a
chicken-n-egg problem..... Nevertheless, I would like to know if I
made any obvious mistakes on the module porting.
Regards,
