Motu AVB devices/Firmware update issues/better DONT update to 1.2.9

Peter Venus
Dear List!

this is my first post to this list, but the issues and solutions i faced
with the MotuAVB devices plus the light push of a fellow linux-user made
me subscribe to this list to share my experiences.


I am a happy user of a Motu 24ao and Motu Ultralite AVB under
Linux(Ubuntu 16.04) in combination with jack/cadence.

almost everything went rather fine until i updated the firmware last
week on my UltraliteAVB:


the current firmware v1.2.9+479
<http://cdn-data.motu.com/downloads/audio/AVB/firmware/io/170621/MOTU%20AVB%201.2.9%2B479%20for%20UltraLite%20AVB%20and%20Stage-B16.update>
(Release Date 2017-06-21) removes the possibility to change the USB-mode
(44/48; 44-96; 44-192) ultimately disabling me to use more then
24channels via USB/class compliant.

With the previous firmware v1.2.8+378
<http://cdn-data.motu.com/downloads/audio/AVB/firmware/io/160901/MOTU%20AVB%201.2.8%2B378%20for%20UltraLite%20AVB%20and%20Stage-B16.update>
(Release Date 2016-09-01)this feature is still available, allowing for
64ch USB-i/o(44/48), 32ch USB-iO(44-96khz) or 24ch (44-192kHz).

According to Motu and tested by myself, a downgrade of the firmware is
possible without bricking the device.

The sad truth is, that the users are locked to this firmware until motu
brings back the feature to change the USB-Mode- unless one loves to
settle with 24ch i/o between computer and device.


regards,

Peter

Thanks for the heads up.

I have not noticed this since I have not needed a lot of channels but I don't like unnecessary limitations. Ultralite AVBs

Do you know if this is registered as a formal feature request or do we have to accept MOTUs way of changing things?

Best regards, Anders

In reply to this post by Peter Venus
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.
