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

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
