command AT+QCFG="usbnet",[ 0 | 2 ] which make the modem enumerate with
the following interfaces, respectively:

"RMNET"	: AT + DIAG + NMEA + Modem + QMI
"MBIM"	: MBIM + AT + DIAG + NMEA + Modem

USB: serial: pl2303: add support for more HXN (G) types 2022-06-22T06:52:03+00:00 Johan Hovold johan@kernel.org 2022-06-21T08:58:55+00:00 ae60aac59a9ad8ab64a4b07de509a534a75b6bac Add support for further HXN (G) type devices (GT variant, GL variant, GS variant and GR) and document the bcdDevice mapping. Note that the TA and TB types use the same bcdDevice as some GT and GE variants, respectively, but that the HX status request can be used to determine which is which. Also note that we currently do not distinguish between the various HXN (G) types in the driver but that this may change eventually (e.g. when adding GPIO support).
