While I got some success with ZTE MF112, with the cold boot configuration
problem left, (see other message in the thread), I can get no satisfaction 
with D-Link DWM-222. Looking at usb_modeswitch and FreeBSD code, it seems 
it is supposed to switch its product ID from ab00 to 7e12 on plain disk 
eject, there is no special handling compared to other devices.

But even after umodeswitch removed the scsibus/sd devices, it gets 
stuck as ab00 as reported by usbdevs:
 port 10 addr 3: high speed, power 500 mA, config 1, Mobile Connect(0xab00), Mobile Connect(0x2001), rev 2.28(0x0228), serial 25052a63011b
    umodeswitch0

I got more information using usbutil:
