1) Try this example Dual Hi-Speed USB Host/Device Solution. Removed all audio functions. Showed write speed 1 mb/s, reading level 4 mb/s. Is this the limit of performance for this controller?

2) What powered the controller? I put usb0 in computer usb slot and board' s pin 5V showed voltage 3.7V, and at pin 3.3V showed voltage 2.6V. Very large voltage drop is not known what is the reason?
