I brought this issue up over a year ago. I tried everything and even putting in a additional USB hub and tried all 7 of my PC's. They are Asus mother boards. I finally went to XIPAR and that solved it. Don't know if going to the Fedora OS had anything to do with it or not. The new XIPAR build is under Centos so I will test this again this weekend and report back.
