Thanks for the code! I wanted to cook up a small example program
to send to the list - now I can concentrate on integrating this :)
Storing the value inside the ftdi_context is a good idea. Also we need some
more safety checks for NULL pointers as dev->config might be missing:
http://developer.intra2net.com/git/?p=libftdi;a=commitdiff;h=a56ba2bd557e7c7804b288aee2dcc42c8037b03c
Maybe some fallback value to 512 / 64 is nice, too, if the config descriptor
is not present or contains a bogus value (like zero).
Cheers,
Thomas
