Hi 
i have an usb 2.0 external harddisk this is the info 

umass0: Maxtor OneTouch, rev 2.00/2.00, addr 2
umass0: Get Max Lun not supported (STALLED)
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <Maxtor OneTouch 0201> Fixed Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 117246MB (240119808 512 byte sectors: 255H 63S/T 14946C)

Why the speed it's so slow? i have a 2.0 usb card :-(
How can i change the transfer speed
