I would really appreciate it if someone would share their USB 3.0 experience under W7 host/guest.  Shortly after my USB 3.0 test failures I installed a new copy of W7 in my guest.  The mouse pointer preformed very strangely until I change the USB back to version 2.0.  It behaved like the focus was not in the VM window.  Most of the time the mouse pointer was a pointing hand not an arrow and left or right clicking did nothing.  If I clicked many, many times it would change to an arrow until I did something, then it would change back to a pointing hand.  There must be some knowledge/fix of/for this.  I am running W7 x64 in both my host and guest and Player 6.0.1 build-1379776.  Thanks and enjoy, John.
