also have usb issues with 15.10 and asus x99e-ws.

get similar error messages as above:
[ 10.918992] usb 1-3: device descriptor read/all, error -110
[ 11.031084] usb 1-3: new high-speed USB device number 3 using xhci_hcd

consequence is that usb devices take a long time to be recognized.
takes a long time to enter the bios (the press f2 prompt for bios waits an abnormally long time)

a complete power down and bios reset fixes the issue temporarily. (no error message at boot up and fast usb device recognition) however this fix is intermittent.

there is only a keyboard and mouse plugged in the usb ports.
