I've two new USB keys, both claiming on its wrapping USB 3.0: usbconfig -v reads from them: ugen0.4: <Generic Mass Storage> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (200mA) ugen0.4.0: umass0: <Generic Mass Storage, class 0/0, rev 2.10/0.02, addr 5> bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0210 bDeviceClass = 0x0000 <Probed by interface class> bDeviceSubClass = 0x0000 bDeviceProtocol = 0x0000 bMaxPacketSize0 = 0x0040 idVendor = 0x058f idProduct = 0x6387 bcdDevice = 0x0002 iManufacturer = 0x0001 <Generic> iProduct = 0x0002 <Mass Storage> iSerialNumber = 0x0003 <A430786F> bNumConfigurations = 0x0001 ugen0.4: <USB SanDisk 3.2Gen1> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (224mA) ugen0.4.0: umass0: <USB SanDisk 3.2Gen1, class 0/0, rev 2.10/1.00, addr 4> bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0210 bDeviceClass = 0x0000 <Probed by interface class> bDeviceSubClass = 0x0000 bDeviceProtocol = 0x0000 bMaxPacketSize0 = 0x0040 idVendor = 0x0781 idProduct = 0x55ab bcdDevice = 0x0100 Both say on plugin "da0: 40.000MB/s transfers"; the USB port itself says on plugin of an external disks "da0: 400.000MB/s transfers", what is expected for USB 3.0; Why both USB keys only reach da0: 40.000MB/s?
