Mavericks USB Hub Oddities

I have the strangest glitch happening with Mac OS X Mavericks and I can’t find anyone else describing the same issue.  I have a D-Link DUB-H7 USB 2.0 hub connected to my Thunderbolt Display which is in turn connected to my retina 15″ MacBook Pro.

USB Hub

If I cold boot with this hub connected to my Thunderbolt Display, both the USB external keyboard (not connected to the hub) and the built-in keyboard have a number of keys that do not function.  I, J, M and a few others I know of offhand that don’t work.  As soon as I disconnect the hub, both keyboards work perfectly.  Also, after I log into Mavericks, the keyboards work fine regardless of the hub being connected or not.

WTF
