That seems misleading on the part of MOTU.  There is no mention of that 
anywhere on the product web page, and the readme file for the "pro-audio 
driver" even has this note:

USB audio class-compliant operation on macOS
All of the MOTU interfaces listed on page 1 of this document are USB 
audio class-compliant on macOS. This means that you can connect them to 
any Mac running macOS 10.11 or higher using USB for multi-channel audio 
I/O without having to install any drivers.

No mention of reduced features when using class-compliant operation.

Is that actually a device limitation, or a linux usb audio driver
