This is just mass storage which comes with the adapter and I guess it  
holds Windows drivers/software for installation.

A u3g driver is part of the new (non-default) usb4bsd stack but like all  
of the new serial drivers it needs the ucom module and that hasn't been  
ported yet, unfortunately. So right now we don't have support. If you'd  
like to take a look at it, the source is in  
/usr/src/sys/bus/u4b/serial/usb_serial.c. The rest of the serial drivers  
(including u3g) compiles and usb_serial.c is the only remaining file that  
has not been ported.

Sorry to have no better news for you.
