we could add a special case for the FT2232H chips,
that would be easy to do.

When I see code like this in the library

if (ftdi->type == TYPE_2232H || ftdi->type == TYPE_4232H || ftdi->type == 
    packet_size = 512;

I'm wondering if the other hi-speed xxxH devices also support this?


libftdi - see for details.
