So , effectively you are limited to 48000.
I supposed that the linux kernel chooses this first valid configuration descriptor.
This behavior can be modified in the kernel with adding a quirk in the code.
If my usbPre2 has the good device descripton, I can devlop and test this patch.
But my devices does not offer the UAC2 configuration descriptor.
I have write a post on the Sound Devices Forum. Perhaps I will have help to understand why my device has this strange behavior and correct it.
In this case, I think I can patch the kernel to have the UAC2 mode...
