Hi, I think you misunderstood my comment. I think that we need some 
trick:

- to tell the u3g driver to use a new quirk (UQ_MSC_NEW) ; that the 
hardware
with VendorID X and ProductID Y *will* need to switch with the next 
message:
ABC - where X and Y are known IDs, ABC is a known message, but ABC is 
not a
defined quirk in the  usb_quirk driver.

So I can tell the system, that the unknown K3772 modem - VendorID=12d1 
and
ProductID=12d1 - needs that message (borrowed from usb_modeswitch 
database)
"55534243123456780000000000000011062000000100000000000000000000"

- to tell the u3g driver, that a HW *will* arrive vith VID X PID Y, and
needs the quirk UQ_MSC_NEW
