I had a similar question but the definition was wrong and i still couldn't find a solution. Actually I am not sure whether this is a hardware or software problem. Here is my problem:
I am using a dual boot system.Windows 8.1 and ubuntu. When i was working on windows suddenly my all usb ports stopped working. Then i switched to the ubuntu. It was working well but if I unplug a device and and plug it to any other port, it kills all the ports. I have three ports including one usb 3 and two usb 2 ports.Let the name of the ports be A,B,C .For example, I plug my mouse to the port A then i unplug it.If I plug it to port B or C. It kills all the ports. But putting it back to port A is no problem. Same situation is valid for B and C too. I use acer v3-571g. No ports are working on windows. I tried almost everything over the Internet. Since the ports working well when I do no not unplug them, can I be sure that this problem is about software? If so why I face with similar problems in ubuntu and windows? Does windows and ubuntu uses any common power management system or something like that?

Moved from Win8 to Linux forum. Appears to be Ubuntu related.
