I should have suggested this to you initially instead of the unusual_devs patch but I got a brain fart
when seeing the switch message Windows used and the result
"Could not claim interface (error -6). Skip message sending" from usb_modeswitch.
The USB Id 0846:0fff will be included for switching by usb_modeswitch in the next update.
This does of course only solve the switching problem, the device USB Id must still be included
in the qmi_wwan and qc_serial drivers.
