>Description:
Huawei E303 USB 3G modem is considered as an unknown device. It is possible to
use camcontrol and/or sysutils/usb_modeswitch port to manually force it to
become a 3g modem recognised by cdce, u3g and ue drivers, but no /dev/cua* and
/dev/ttyU* /dev-entires are created.
After usb_modeswitch* there is a message in dmesg stating
May 19 16:05:03 avantgarde root: Unknown USB device: vendor 0x12d1 product
0x1506 bus uhub1
*usb_modeswitch command used was 'usb_modeswitch -v 0x12d1 -p 0x14fe -V 0x12d1
-P 0x1506 -s 20 -M
