HPS, Not sure whether this is actually a problem, but you might want to have a look at the switch command for ZTE devices in the FBSD7 code base. it uses a ZTE specific command. The ZTE 636 device here switches properly using that command sequence. On another note, that device presents alternate interfaces, as in, interface 0 and 2 have alternates 1 and 3 resp. How does the new stack handle that? Can you set these alternates during attach? If so, you might want to do that for ZTE devices, as the alternates probably contain the additional serial ports. Below the descriptor dump for those devices.
