I can confirm that USB Mass Storage causes kernel panics ~50% of the time. This happens during detection/initialization of the device. Leaving the drive in during boot has the same chance of panic. It is not 100%, as sometimes I can get the drive to register and use it. I've yet to see any other USB device have an issue though. I'm actively using a USB-3 hub with keyboard, mouse, and ethernet without issue.
