Hello! I am working on designing USB audio class 2.0 device, based on stm32f722 with high speed USB external PHY USB3300. In USB audio class 1 mode the device works fine, but in UAC 2.0 mode device enumeration fails. Device descriptor and USB analyzer screenshot are attached.
Any ideas would be very useful. Thanks!
