USB device has exceeded the power limit

The USB ports on my computer a Dell Precision 390 failed. I inserted a new USB PCI 2 card inside my commputer after I recieved the above thread notice. Everything was working fine until I received this error notice again and my computer froze up. Any suggestions?

  1. Looks like you may have a short in a USB cable / component. I'd pay attention to what was plugged in and try to eliminate the item.

    Either that or you have a few IPADs or high draw devices plugged in at the same time.
