Hi,

Thanks for the replies. I tried kldload ugensa, then to see if it
worked I disconnected the modem and connected again.

Turns out that was a very bad idea, my entire screen was flooded with
this message (again and again and again):
xptioctl device pass not supported by kernel
xptioctl put "device pass" in your kernel config file

I could type into the terminal but couldn't see the output of anything
else because this message flooded my entire screen.

I reboot and type usbdevs to find out that the ZTE WCDMA device is
actually connected to address 5. Well, I still don't know which thing
on /dev it actually is. Is it /dev/sg8, /dev/da8, /dev/cd8? All of
these are ZTE MMC or WCDMA as per the dmesg output.

Are you talking about usb_serial.c in the FreeBSD source? I'll try to
see if I can understand that (I know C programming but I know nothing
about drivers, but I'm willing to fiddle around with it).

Regards,
Rama
