Well, I've got a situation regarding USB 3 but haven't really had time to get it resolved.
I bought a 1TB Toshiba Canvio external HD, labeled as USB 3.0 and 2.0 compatible. I used it in my 2009 iMac (Lion) and all was well (but obviously at USB 2.0 speeds). Then I bought a new 2012 MBP, and the drive does not work. An indicating light on the drive that is normally white when connected lights up a pretty azure blue, but the drive never shows up in finder.
After a little internet research, I found this problem to be fairly widespread, and came upon a crap-tastic solution. The business end of a micro USB cable fits into a portion of the drive's connector. Plugging the other end into the MBP results in instantaneous white light and drive mounts in finder, ready for use at . . . USB 2.0 speed. Fun.
I've been scanning these forums for anyone else having this problem but didn't see anything of note.
Anyone have any ideas what's going on here? Apple's fault? Toshiba's fault?
