[LAU] Motu AVB devices/Firmware update issues/better DONT update to 1.2.9

[Anders Hellquist]

I filed a support request about this new limitation and the quick response
was unfortunately  not that hopeful.

The guy just stated that more than 24 channels over USB is only avaliable
when using the Windows or Machintosh driver and I would need to downgrade
to be able to use more.
I told him that there are a lot of users that are using Class compliant
OSes and this is a problem. Also told him to update the firmware Change log
to include a Warning that this will happen and also to update the FAQ

Asked him if we can expect more limitations for Class compliance mode down
the road and that this was something that had been nice to know before
purchasing in my case 2 interfaces.

No information on why this have changed or if it will be reintroduced later
on.
