>Description:
NetBSD-current does not support the Sierra Wireless USB305 (aka AT&T USBConnect 
Lighting) USB dongle. It is a USB HSPDA serial device with a U3 CD image for 
driver installation. It is also a umass device with a port for mini-SDHC cards.
>How-To-Repeat:
In NetBSD-current, the device comes up as unconfigured. 
Currently, it will connect as u3ginit and announce that it is switching to 3G 
mode. After that, it will connect as a ugen device. 
>Fix:
The Sierra Wireless USB305 works as a ugensa device.  The USB ID is 0x68a3. I 
was able to connect to the AT&T HSPDA network by modifying the following files 
to add in the USB ID and use it as ugensa device.

u3g.c
ugensa.c
