Since your patches deals with Option cards I'll just let you know that
all(?) Option based devices can be switched perfectly safe from
user land, without patching ubsa, using camcontrol.
The command to switch Option devices is a SCSI REZERO command.
This should be enough to switch the device, given that pass0
is the modem (use camcontrol devlist)
camcontrol cmd pass0 -c “01 00 00 00 00 00″ -i 1 i1
camcontrol might give you an error but the device will be switched.
Note that this is ONLY for Option based devices, I don't know about
the Sierra ones but the linux usb_modeswitch tool might be a good start.
