Here's two out of three for you to look at. They're all listed in drivers/usb/serial/mdm6600.c in at least the Motorola Mapphone Android kernels, see for example the LineageOS kernel at [0] if you want to look at the USB serial driver. I don't have a device with 9600 with 0x2e0a id.

Yes, the wrong lsusb output is for the flash mode that we're not adding here and can be ignored for now. > Could you post the output for the two devices you have in "modem" mode? Yes correct lsusb -v output below with five UARTs with ff/ff/ff and two QMI ports that are already handled with an earlier commit 4071898bf0f4 ("net: qmi_wwan: Add USB IDs for MDM6600 modem on Motorola Droid 4"). > How do switch modes by the way? The flash mode gets enabled with the control GPIOs. I just did a quick test patch for phy-mapphone-mdm6600 using module param for that. Then additionally the modem USB can be multiplexed to the PC by configuring mode in phy-cpcap-usb but I don't have a patch for that.

FYI, below is the test patch against next I used for switching between normal mode and flash mode with a module param flash_mode if somebody wants to play with it. For flashing the modem, Android update-binary does it to deal with the signed modem firmware, I don't know of the details what happens there. Kishon, is there maybe some phy framework sysfs property we could use for switching phy modes?

On Motorola Mapphone devices such as Droid 4 there are five USB ports that do not use the same layout as Gobi 1K/2K/etc devices listed in qcserial.c. So we should use qcaux.c or option.c as noted by Dan Williams <dcbw@redhat.com>. The ff/ff/ff interfaces seem to always be UARTs on Motorola devices. And we should not add interfaces with 0x0a class (CDC Data) as they are part of a multi-interface function like for example interface 0x22b8:0x4281 as noted by Bjørn Mork <bjorn@mork.no>. The ttyUSB ports on Droid 4 seem to be: ttyUSB0 DIAG, CQDM-capable ttyUSB1 MUX or NMEA, no response ttyUSB2 MUX or NMEA, no response ttyUSB3 TCMD ttyUSB4 AT-capable To enable the MUX or NMEA ports, it seems that something needs to be done additionally to enable them, maybe via the DIAG or TCMD port. Who knows, maybe it's just some NVRAM setting.
