A few days ago someone posted info about what happened when a couple of Apple devices were plugged into a USB port on an OpenBSD system. I just had the opportunity to try this with an iPad2 and an iPhone4S on an amd64 system running current (source tree updated to about 2200 EST 2011/12/20 before rebuilding the system); here are the results.
