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).
The "MBIM USBIF" label comes from on-device help:
---8<---
AT!USBCOMP=?
!USBCOMP:
AT!USBCOMP=<Config Index>,<Config Type>,<Interface bitmask>
<Config Index> - configuration index to which the composition applies, should be 1
<Config Type> - 1:MBIM USBIF, 2:PCIE USBIF, 3:Legacy-Generic, 4:RNDIS
<Interface bitmask> - DIAG - 0x00000001,
NMEA - 0x00000004,
MODEM - 0x00000008,
RMNET0 - 0x00000100,
MBIM - 0x00001000,
e.g.
10D - diag, nmea, modem, rmnet interfaces enabled
1009 - diag, modem, mbim interfaces enabled
The default configuration is:
at!usbcomp=1,3,10F
OK
