This change was discovered and tested using author's own EM7565 device.

This "MBIM USBIF" configuration corresponds to the `AT!USBCOMP=1,1,xxx`
on-device USB composition setting. When activated, the VID:PID resets
to 1199:90b1 ("application" mode) + 1199:90b0 ("boot" mode, i.e. QDL).

Hi Ivan,
for the whole series 1-5, please include an lsusb -v or usb-devices listing for any device that you add support for.
What you find in device firmware or in Qualcomm SDK drivers does not necessarily reflect what has actually been manufactured and consequently how those Id's could be used for a future different product.

The 1199:90d3 is already supported by the option serial driver and that is where devices with interfaces supported by their unique interface attributes belong instead of being supported by interface number in qcserial.

thanks
Lars
