I wrote a patch to send special request to enable modem function of
E220 deivce. It seems to work well (I use OEM version of E220 /
Emobile D02HW). (special thanks to ichiro@netbsd.org)

Once the device is plugged in, this patch act as
attach -> send special request -> re-attach -> attach as ucom.

Following is dmesg:

ubsa0 at uhub0 port 2
ubsa0: HUAWEI Technologies HUAWEI Mobile, rev 1.10/0.00, addr 2
ubsa0: HAUWEI E220 need to re-attach to enable modem function
ubsa0: at uhub0 port 2 (addr 2) disconnected
ubsa0 detached
ubsa0 at uhub0 port 2
ubsa0: HUAWEI Technologies HUAWEI Mobile, rev 1.10/0.00, addr 2
ucom0 at ubsa0

This patch is send-pred.
