Query: Runs hot, died after a year

I was initially really excited about this as well, since the metal construction seemed really solid and reliable. But, it may be for a reason. The device generates a lot of heat, and it's performance degraded over time. A couple of months ago I started getting warnings from Vista that the hub was no longer running at 2.0 speeds, and transfers to my disk drive were getting slow and unstable. Then, last week, it died entirely, showing up as "unrecognized device" in the OS.
