Thanks!

I have been testing the patches for a while now and they work without
issue. I'm also testing the libhinawa and hinawa-utils code in the
process. I haven't tested the channel level values from the isochronous
packets as I haven't a need for that so far. I see that the data
changes as expected, but I have not verified if the values are
accurate.

But my primary need was the control surface. Between what you already
had hinawa-utils and the kernel patches to pass the isochronous data to
userspace, I'm able to react on all input from the controls as well as
set the fader positions and light the LEDs. I will submit a pull
request to hinawa-utils for controlling the LEDs and Fader positions
for the FW-1884.

Thanks for your help!

Regards,

Scott
