Power Surge on Hub Port

Hi. I've had a USB-UIRT for a few weeks now and I'm using it with SageTV. I'm using a trial of Win2k3 on an older AMD Thunderbird with an MSI motherboard. The USB-UIRT is the only item I have plugged into the USB ports.
Every few minutes to few hours, my USB-UIRT will stop working. I won't be able to change channels and I don't see the red light flashing on the front of it. When I exit SageTV, I'll see the "Power Surge on Hub Port" error message. When I reset the port, my USB-UIRT works again. I don't think it's coincidence.
What might be coincidence is that the Hauppauge remote that came with my PVR-250 card will also stop working intermittently, but I'm just throwing that in here as info, since I don't think it happened before installing the USB-UIRT.
What can I do to solve this problem? I'm using a USB2 port plugged into the motherboad via daughter card, provided by MSI with my motherboard. I'm wondering if buying a USB2 PCI card might solve this problem, but I don't really want to spend the money and time if it's not going to solve anything.
Thank you very much!
