Hello Alexander,

Thanks for your email!

Unfortunately, the MF192 I have does not present with a
pseudo-ethernet interface. Just the ttyACM* interfaces.  Dmitry
Morozhnikov patch works for me. Do you have a suggestion that can help
me expose a pseudo-ethernet interface if the device has one? Also,
note that my device has the ID: 19d2:1519, and the latest
usb_modeswitch data packages switches it to a device with ID:
19d2:1519.

I see that the original report I sent to this mailing list failed to
go through because I attached a full USB trace of the device working
in Windows (in VirtualBox) and captured using wireshark. I will resend
that email without the original attachment shortly.

Many thanks!
