Yes, the basic usb2 hub support that was added to FreeBSD in August has recently looped around via OpenBSD to NetBSD and picked up some enhancements along the way (OpenBSD added improved suspend/resume support, and NetBSD have begun adding transaction translation support). There's a patch against FreeBSD -CURRENT at http://people.freebsd.org/~iedowse/usb2_sync.diff that attempts to sync up our USB stack to include the latest USB2 changes from NetBSD. If you've been having trouble with EHCI it would be worth trying it. IanReceived on Sun Oct 31 2004 - 10:59:53 UTC
