I filed a PR with a patch that has been taken into the UHCI driver in -CURRENT : http://www.freebsd.org/cgi/query-pr.cgi?pr=73000 Can you try the patch that's at the end of the PR on your system? (It should patch without a problem on 5.2.1-RELEASE). I'm not sure if it fixes your problem since your problem seems to be EHCI-related, but you never know. Good luck, Daan
