Hi,
I think that I'm near solution for my problem. As I mentioned I'm using Option Icon 225 3G modem and that is the problem. This modem need its own driver not the one compiled in pfsense (u3g). I compile correct driver (uhso) on freebsd 8.1 to get uhso.ko file, I put that file in boot/kernel and in kernel.conf I added the line uhso_load="YES". When I attach my usb card it try to use uhso driver but it get detached immediately and than reattached and load u3g driver. Can I, somehow, disable u3g driver? This is driver compiled with kernel.
Thanks,
Nikola
