troubles with a usb2 external hard disk

[dave]

Hello,
    I'm atempting to get a USB2 external hard disk working on my 5.3-stable
box cvsupped as of about an hour ago. The startup messages from dmesg are at
the end of this message, i'm not sure if they're errors or what. The
controller is a ehci controller, USB2, my first complaint is it's only doing
1.00 mb a sec, that sounds like usb1 to me, this controller and device are
both 2.0 capable. Secondly, fdisk, newfs, bsdlabel, mount, the procedure for
adding disks in the handbook, all return read input/output errors. Any help
appreciated.
Thanks.
Dave.
