It is running high speed, because it is attached to your ehci controller.

The OS version might also influence throughput. > Controller /dev/usb3: > addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), > Intel(0x0000), rev 1.00 > port 1 powered > port 2 powered > port 3 addr 2: high speed, self powered, config 1, USB2.0 Storage > Device(0x6830), Cypress Semiconductor(0x04b4), rev 0.01 > port 4 powered > port 5 powered > port 6 powered -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
