So, they do but it seems selective. On my 2008 iMac I would plug in my thumb drive and it was near instant but on my MBA ill plug it in on the right side and it rarely works but my mouse works fine there. On the left side it takes a few seconds then it works but it seems longer than my older macs. This computer isn't old about a week old, so ideas. Its not a mounting issue it dosen't show up in the disk utility, until it works.
