For usb2 bMaxPacketSize0 is "n", for usb3 it is "1 << n", so it must be 9 not 64 ... rom "Universal Serial Bus 3.1 Specification": If the device is operating at Gen X speed, the bMaxPacketSize0 field shall be set to 09H indicating a 512-byte maximum packet. An Enhanced SuperSpeed device shall not support any other maximum packet sizes for the default control pipe (endpoint 0) control endpoint. We now announce a 512-byte maximum packet.
