>Description:
Nokia 6630 does not work as modem when connected by USB cable.
It is defined as ugen device:
ugen0: Nokia Nokia 6630, rev 2.00/0.00, addr 2
It seems that this phone return ACM descriptor to umodem driver,
but does not return CM descriptor.
It's work fine after patching:
ucom0: Nokia Nokia 6630, rev 2.00/0.00, addr 2, iclass 2/2
ucom0: data interface 9, has CM over data, has break
ucom0: status change notification available
