1) Played a 192/24 pcm sample from the NAND. No improvement. The result was the same as playing from a usb storage.
2) Measured Freescale's USB bandwidth by copying a file from one usb storage to another (with USB hub). The speed was about 50 Mbits/second which should definitely be enough or 192/24 content playback - it needs approx 20 Mbits (192kHz * 24 Bits * 2 channels * 2 paths - one for reading data from USB storage and other for sending them to USB DAC).
