Hi,

I just acquired one of these cards, it attaches as a USB cardbus device.
I have similar problems with Huawei E630, and not just me

Panics are fixed with usb4bsd ... :)
I didn't find time to get the card actually working and receive a lot of those:
ubsa_cfg_request: device request failed, err=USBD_ERR_STALLED (ignored)

This is just to say that I can reproduce the problem described here:
   http://www.rinta-aho.org/docs/option3g/option.html

The driver support was originally committed here:
   http://www.freebsd.org/cgi/query-pr.cgi?pr=112161&cat=

...the ubsa driver attaches to the virtual modem port.

If I unplug it, the kernel panics.

The panic is in kobj_delete() (a null pointer reference) and it's on the usb detach path. Unfortunately I wasn't able to get a backtrace this time around.

PS Does anybody know if ubsa will be ported to the new USB driver framework?
I think it is because ubsa works with usb4bsd and it's basically the same?

cheers
BMS
