Here's my problem, the system processes takes all the CPU and USB ports are unusable; whenever I plug something into it.
I'm on HP Pavilion zv6279EA laptop that runs Windows XP SP3. In fact all the drivers are up to date and Windows too.
I, at first, thought of a hardware problem. So I tried to boot from a live CD that contains a version of Windows XP and the problem is the same. But, with a version of Linux live CD at hand, I do the test. Of course, impossible to see whether the "system processes" takes all the CPU but my USB mouse works like a miracle. I then decided to connect my external USB hard drive that also works perfectly.
Finally, I am in the dark because a total test tells me that hardware and other software.
