Comment 9 for bug 1506704

Recently I had a bad USB hub. The computer had a problem with going past the POST phase and apparently Ubuntu had a problem loading as well. After it did load, the problem in question occurred EACH TIME, and furthermore, mouse cursor would momentarily be replaced with an ugly cross. Apparently the problem may be occurring when Ubuntu cannot properly load due to other hardware failures. Three days after I replaced the USB hub I haven't noticed the problem.
