I found a really good deal on a 24" LED Cinema Display on CL. I got it home, it looks nice and all. Everything works except the two outer USB ports. I've tried this connected to both of my MBP's USB ports and one on my new (to me) mini. It looks like the inside one might work as it makes an external drive's light flicker, but won't read it. Middle one seems to work fine. It's not a power issue, I don't think, because a USB keyboard won't work on them either. Is there a way to reset firmware or is this maybe a known issue for this or do I just do without? I really don't care for them back there since they're a bit of a hassle to get to.
