USB Hubs freezing.

So at work, I have a USB Hub. It connects about 4 devices together. Total bandwidth is probably a few megabytes per second.
The problem is that these devices seem to freeze... frequently. I have tried several models of Hubs and they all freeze. The computer seems to be fine and doesn't have these problem when the individual devices are directly connected. Data communication will continue for days with the direct USB connections.
Are Hubs really this shitty? Are there any Hubs designed to be robust? Perhaps a watchdog timer or an external, software controllable reset?

I have external power for the hub and many of my devices require external power.
I have a test running wit this scenario, presently. Hopefully it will be much better.
As a side note, I am trying to get some interest in switching the National Instrument's Compact DAQ for this stuff. I can do everything with a single USB device. It'd be a lot easier and when stuff goes bad, I can normally reset the cDAQ where it can be hard to reset multiple devices (or impossible when a hub is involved) through software.
Cost kinda sucks since it is about 4 times as expensive, but it is much, much more stable.
