USB devices aren't working

Recently i had a problem with my usb mouse not working, and i thought it was just a problem with that mouse. However i recently discovered that no usb is working on my computer.

dmesg | grep usb

ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
ehci_hcd 0000:00:12.2: new USB bus registered, assigned bus number 1

I've tried the following: Removed modules ohci, uhci, and ehci and tried modprobing them seperately. I've reinstalled ev-dev and tried a previous linux kernel. However none of these things are working.

Does anyone have a solution?

Re: USB devices aren't working

Perhaps there is a legacy USB item in your bios.  Enable legacy usb if it is.......

Re: USB devices aren't working

Check your kernel version:  I think this may apply:
