USB peripherals not working on hub after reboot

Hi All,

Here's my setup: I have a Mac Mini mid 2011. Three of out the four USB port on the back are used for keyboard and 2 external hard drive. One is being used for a powered USB hub (Trust 4 port Pyramid USB hub, it's powered).

On that USB hub I have my headset, webcam and using 2 ports for external DVD drive/burner.

Now here's the issue. If I start from scratch, i.e. plug the usb hub, plug the webcam, then headset then the dvd burner everything works fine.

On shutdown and restart the hub is completely toast. I have to unplug the hub and start from beginning again.

Anyone has any idea how to fix this issue? It's rather annoying because I do shutdown the Mac on regular basis.
