None of the USB ports work anymore on my Acer Aspire E1-571G laptop which is running both Windows 7 and Fedora 21. It can’t detect anything. For example flash memories, USB mouse, my Android phone which connected with USB cable. The phone is charging but Windows and Fedora can’t mount it.
I also tried the suggestions in this answer but nothing happens.
This is dmesg output in my Fedora Linux install:

I found this link How to fix "device not accepting address" error . I think there should be some power issues but i don't know what i should do !
