uftdi support for "extended functions"

["Martin Hinner" <martin%hinner.info@localhost>]

Hi,

 I am working on FTDI's FTD2XX.DLL support for Linux (as an
open-source project, I am not connected with FTDI in any way) and I
was thinking about making something similar also for FreeBSD/NetBSD since my
code is easily portable and requires  only few changes to ftdi serial
driver (uftdi in *BSD case).

Some results of my work (basically only patch to Linux kernel driver)
is here: http://martin.hinner.info/ftdi/

The point is that userspace application needs to send custom USB
requests to the device in order to enable BigBang mode, read internal
eeprom, etc. Do you think this would be possible to do with uftdi ?
One way is via ioctl, but I am not sure if this is way BSD would
accept to go with...

Let me know,

Martin
