Is 96kHz or higher sampling frequency tested with stm32l4 series?

Hi Dear USB developers!

I would like to ask whether Full Speed 96kHz or higher sampling frequency has been tested for the current dwc2 driver with stm32l4 series or not, thanks a lot for answering my question!

96kHz and 192kHz are possible to implement.

ISO endpoints are not implemented for STM32L4x2 and STM32L4x3.

It should work on STM32L4x5 and STM32L4x6, but I'm not sure if it's been tested or not.

With full-speed USB, you will need to be careful about bandwidth at higher sampling rates.
