Thunderbolt USB not working in Yosemite
I updated to the latest OS Yosemite and now on both my Thunderbolt displays none of the USB's work at all. I have external hard drives connected to them and they wont turn on at all. They are not getting any power from the USB's. I have tried restarting multiple times. Unplugging an plugging everything back in but nothing seems to work. Apple needs to send a patch for this ASAP. It is a huge part of my work life.
MacBook Pro with Retina display, OS X Yosemite (10.10)
