Sorry for the late reply, failed to notice this topic before ...

It should be fairly easy to add support for your device. There is a limited number of things to try.

Get the latest data package, unpack and see the folder "usb_modeswitch.d". For the first attempts, it's more convenient to use the command line, taking the "MessageContent" string from the respective config file; you can provide it with the "-M" parameter.

Example with the string from "19d2:ffe6":

Code: Select all

# usb_modeswitch -I -v 19d2 -p ffde -M "5553424330f4cf8124000000800108df200000000000000000000000000000"

If that does not work, replace the long string with the one from files "19d2:fff5" or "19d2:0013". It's highly likely that one of those three will do the trick.
Check with lsusb each time. Replug before each new attempt.

I am not sure how usb_modeswitch is called automatically on OpenWRT when plugging in the stick. You may have to figure that out once you found the correct "MessageContent".

You can use this...

Code: Select all

# usb_modeswitch -v 19d2 -p ffde -V 19d2 -P ffdd -M "55534243123456780000000000000011060000000000000000000000000000"

on OpenWRT, you need to modify /etc/modules.d/60-usb-serial first (and reboot before you execute the command above)

Code: Select all

usb_serial vendor=0x19d2 product=0xffdd
