I've had Yosemite running with the Clover bootloader for about two weeks on my ProBook 4530s and everything was working just fine. Now it seems that my USB ports won't operate correctly once I've booted into OS X. Plugging in a hard drive results in the the drive's icon popping up on the desktop and then disappearing followed by a "Disk Not Ejected Properly" message. Leaving the disk plugged in just results a continuous cycle with disk icon appearing on for a couple of seconds and then disappearing for a couple of seconds. Disk shows the same behavior in Disk Utility. USB sticks show the same behavior. I've plugged this disk into my other hack (Yosemite/Chimera) and it works fine.

Try EC reset.
