USB Modeswitch has nothing to do with it, besides it doesn't work. ;)
Actually the device switches mode by itself. ;) 'pid 140c' is inherited
through a warm state(reboot) from proprietary OS. However if the device
is replugged(cold state) within the Linux kernel, it switches to the
'pid 1436' mode.
And vice versa.

Super duper!
