I got an Option Globesurfer iCON 7.2 last week.  I tried the similar
usb_modeswitch program:

http://www.draisberghof.de/usb_modeswitch/

I found out that the driver detach is not needed on FreeBSD, so I just
ifdef:ed out that part of the code (including both *_np calls - see
attached patch).

It however seems that the ugen driver has to be attached to the device
for libusb to find it.  No driver or the umass driver results in the
device not being found.  I am working on another variant which uses
the method for finding the device Rui Paulo wrote in his reply to your
mail to make the program independent of loaded drivers.

Then you need to add the vendor/product id:s to ubsa.c and usbdevs
(second patch - apply in /usr/src/sys/dev/usb & make all install in
/usr/src/sys/modules/{usb,ubsa}, or rebuild kernel if you have it
built-in).

Regards,

Bengt
