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.
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

I just got that hub and ran into the same problem. Any solution? Get another hub?

Yes I ended up getting another hub and haven’t seen the issue since. I’m glad I wasn’t the only one seeing the problem!
