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 Thanks, Gabor < Gabor at Zahemszky dot HU >
