Hi,
I just acquired one of these cards, it attaches as a USB cardbus device.
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?
cheers
BMS
