Sorry for the delay in responding - I'm travelling and attending LCA2010 in
Wellington NZ at present.

I missed the release of the hybrid series from MOTU (mostly due to
Christmas, travel and the like). Having both USB2 and firewire on the same
device is an interesting approach.

The current state of play regarding all the Mark3 devices is that we need to
complete the discovery of the control protocol. There is unfortunately no
easy way to do this by simply running test programs - one needs to intercept
the control packets and this requires special hardware (a PCILynx-based card
in a second PC on the firewire bus) in the simplest case. I've outlined the
process in earlier posts to the ffado-devel list - perhaps contact me
privately if you have difficulty tracking these down.

Ah. If you're using this device through USB2 then the ffado project cannot
help. FFADO is relevant if you're using firewire to connect to the device;
FFADO does not support USB and, due to the very different structure and
operation of the two buses, is unlikely to in the foreseeable future.

To obtain USB2 support for this device FFADO is the wrong project,
unfortunately. I'm not certain where you should go to enquire about this.
At the moment most if not all USB-audio devices supported by Linux are done
through ALSA, so it might be worth posting a message on the alsa-devel
mailing list to see if they have any thoughts as to where this device might
As an aside I'd be interested to hear how well this device works under USB2
(under any OS). USB2 traditionally has had technology-related issues with
applications such as high channel count audio interfaces. It would be
interesting to see if MOTU has found ways around those issues and can drive
the mybrid via USB2 as hard as you can via firewire.
Once again, sorry for the delay in responding to your original post.

That would be truly awesome! I'll ping you off-list and we can discuss
