The Alcatel TD10 USB to Serial converter cable (for use with a Alcatel
OT 535 or 735(i) mobile phone) seems to be a repackaged Alcatel
version of the Prolific 2303 adapter.

And as such, simply adding its product/vendor id (0x11f7/0x02df) to
drivers/usb/serial/pl2303.c seems to be enough to make it work.
