No, still having some daily USB freeze. However what I have been noticing is it will freeze on a 'USB Eject'.
For example I have a Lacie USB3 drive with music on - this will get ejected at random and I get the little window telling me it's done so.. need to reboot to be able to do anything.
I've also been playing around with the physical plugging in of and the usb.kext for USB3/USB2 configuration.
All USB2/USB3 devices will now be on separate ports once my new hub arrives.
I had also noticed not only would it freeze on USB eject but also on physically unplugging a cable.
@boob previous comment about the bridge seems like it may be connected and somehow is just ejecting or failing to see the USB.
