description:
Huawei K3765 requires another kind of magic to get it out of CD mode.
It also changes product id after being configured. Without this
change the device just lingers in u3ginit forever. With this change:
u3ginit0 at uhub0 port 1: Switching to 3G mode
u3ginit0: detached
u3ginit0: at uhub0 port 1 (addr 2) disconnected
u3g0 at uhub0 port 1 configuration 1 interface 0
ucom0 at u3g0 portno 0: 3G Modem
u3g1 at uhub0 port 1 configuration 1 interface 1
ucom1 at u3g1 portno 1: 3G Modem
u3g2 at uhub0 port 1 configuration 1 interface 2
ucom2 at u3g2 portno 2: 3G Modem
u3g3 at uhub0 port 1 configuration 1 interface 3
ucom3 at u3g3 portno 3: 3G Modem
(tested with rump)
