Hello, 

I have a quick question, and I cannot find answer anywhere on the web (including Reference Manual for MCU). I'm preparing for a new project, picking master unit, where one of most important feature is USB audio input (and if possible output). I already know that M3 based devices have too small buffers to run 96 khz / 24 bit so I went for STM32F429 (yeah, I know go big or go home, but I need extra SDRAM) with external PHY for max speed avaliable. 

However when I try to configure middleware with CubeMX for Audio Class with 96000 Sa/s i tells me that maximum frequency is limited to 48 ksa/s. Is it cubemx bug or usb core is really incapable of 24bit/96Khz mono input?

/edit: I suppose it is CubeMX bug, therefore I posted in this forum.
