Bug Description
On my Asus n55sf laptop running 64-bit Ubuntu, USB ports gradually fail more and more until none of them works, progress can take weeks.
Rebooting provides partial relief (but symptoms come quicker, e.g. within days then within hours. Observed with all sort of devices. Not device dependent or trigger by any specific device. actually affects USB3 ports first, then extend to USB2 ports. Machine has 2 USB3 ports on the left, 2 USB2 ports on the right. The laptop also has Windows 7 64-bit which is rarely used (say, 20 days in 2 years). All USB ports always work on Windows, no disconnect, no glitch, USB2 as well as USB3 ports fully work.
WORKAROUND: Booting Windows for a minute solves (no problem for weeks).
