So I put it down to a hardware issue. All other ports work as expected. Is it an external hard drive, as opposed to pen drive etc? Have you tested with the supplied cable plugged directly into a usb port (no extender cable) including with the secondary power cable if it has one? Have you tested all your usb ports? Have you tested on other machines running FreeBSD? Finally, given your remark about windows 98, does your motherboard actually have USB 2? FreeBSD 8.0-RELEASE-p1 regards Chris
