Correction (just now testing again):

For the UltraLite AVB, at least for my very recent hardware version, 
firmware 1.2.8 and 1.2.9 do not install (the Motu claims it is too old 
for the card, try with a newer one).

Firmware 1.3.2+520 does install, and it looks like it does not have the 
"input channels hop over groups of 8 every once in a while" feature. I 
presume 1.3.4+ breaks usb input.
