Subject: libftdi bitbang for CH341

Good day,
 Can libftdi be modified to work wit the CH341 (and similar) devices in bitbang mode?
findal_pp failed as:

find_all_pp -v 0x1a86 -p 0x7523
Found devices ( VID: 0x1a86, PID: 0x7523 )
------------------------------------------------
FTDI (0x12a5710): , ,  (Open FAILED)

I am trying this in the context of an LIRC IR transmitter. I have tried transmitting and libtdi complains it cannot connect to the device.
I assume that something as simple as modifying lines 334-336 in src/ftdi.c in git to include the VID/PID will not be enough.

Cheers,

Jasper
