I'm trying to move away from adding such defines for new devices as they
do not really add any value so I dropped them from the patch.

Also, would you mind posting the "lsusb -v" output for this device for
reference? Do you know what each interface is used for?

I've applied this one locally, but I'll await your reply before pushing
it out.

The lsusb from busybox on this system doesn't support the -v option it seems.
Here is the output from /sys/kernel/debug/usb/devices:

I can rebuild my rootfs with the usbutils lsusb tomorrow when I have
physical access to it again if needed.

The second tty responds to AT commands. The others don't do anything so far.
The hardware documentation doesn't say much aside that there is a usb interface.

Thanks,

Daniel

That's ok, the above will do just fine.

It looks like we must not try to bind to the first two interfaces
however:

{ USB_DEVICE_INTERFACE_CLASS(0x2df3, 0x9d03, 0xff) }, /* LongSung M5710 */

Ok, thanks. I'll apply this one with the above change now.
