What you refer to as begin working properly, are enumeration problems. The big difference between EHCI and XHCI, is that certain commands like the initial SET address is now a high-level command, and some controllers don't provide an ACK on that message, leaving you with a TIMEOUT stalling the command queue on the host controller: http://svnweb.freebsd.org/base?view=revision&revision=264294 > > P.P.S.
