I investigated issue by capturing USB packets on different systems (windows,
macos) and discovered that there is no communication with synchronization
endpoint. I commented psync_xfer calls, but the problem persisted, but when I
commented usbd_open_pipe call the problem is gone. What I can collect for this
issue? Info about device: uaudio_process_as_ep: addr = 0x8, async/data,
maxpktsz = 400, ival = 1 uaudio_process_as_ep: addr = 0x84, unk/feed, maxpktsz
= 4, ival = 4 mode = play, ifnum = 1, altnum = 1, addr = 0x8, maxpkt = 400,
sync = 0x84, nch = 4, fmt = s24le4, rates: 44100 48000 88200 96000 176400
