I want to mount an external usb20 HD. I try this:
#mount_msdosfs /dev/da0s1 /mnt (yes it is in Fat32 for windows
compatibility, I need it)
and it works, but I think that it is mounted like an usb1.1 device
because the transfer speed is very low.
# diskinfo -tv /dev/da0
/dev/da0

200049647616 # mediasize in bytes (186G)
390721968 # mediasize in sectors
24321 # Cylinders according to firmware.
255 # Heads according to firmware.
63 # Sectors according to firmware.
