While the existing calculation for EP OUT capture for async mode yields size+1 frame due to uac2_opts->fb_max > 0, playback side lost the +1 feature. Therefore the +1 frame addition must be re-introduced for playback. Win10 enumerates the device only when both EP IN and EP OUT max packet sizes are (at least) +1 frame.

If left at 0, the UAC2 function is unable to transact data on its playback or capture endpoints in SuperSpeed mode. Since f_uac2 currently does not support any bursting this value can be exactly equal to the calculated wMaxPacketSize. Tested with Windows 10 as a host.

Add a new ss_epin_fback_desc_comp descriptor and append it behind the ss_epin_fback_desc both in the static definition of the ss_audio_desc structure as well as its dynamic construction in setup_headers().

But because of the || vs && bug, it will never time out and instead it will loop a minimum of 30,000 times. This bug is quite old but the code is only used in USB_DEVICE_TEST_MODE so it probably doesn't affect regular usage.

Tests have revealed that Win10 and OSX UAC2 drivers require the feedback frequency to be based on the actual packet interval instead of on the USB2 microframe. Otherwise they ignore the feedback value. Linux snd-usb-audio driver detects the applied bitshift automatically.
