Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 kernel[0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Status in “linux” package in Ubuntu: Incomplete Bug description: # Summary On an Asus n55sf laptop running 64-bit Ubuntu, USB ports gradually fail more and more until none of them works. # Expected * USB devices work at all times. * Plugging optical mouse shows light under the mouse, the mouse works. * Plugging USB memory, hard drive, phone, work and lsusb reports them. # Observed, summary To summarize: * total (all USB port totally unusable) but progressive failure (first one, them more ports, progress can take weeks), * rebooting provides partial relief (but symptoms come quicker, e.g. within days then within hours), * can go on till all USB ports fail, * booting Windows for a minute solves (no problem for weeks). # Observed, details Observed with all sort of devices. Not device dependent or trigger by any specific device. Partial fail: * sometimes some port works but things behave like hard disk or USB key was unplugged/replugged -- can happen several times within minutes. Total fail: * if a device is plugged at failure time, Linux behaves as if it was unplugged (as shown in logs) * plugging device into a failing port, device is not seen by Linux (nothing in dmesg or any log). * port will continue to fail after un/plugging devices. * port will continue to fail after suspend/resume to RAM (have not tried suspend to disk) * port still provides power to e.g. recharge a mobile phone Workarounds: * rebooting the machine have ports work again (but symptoms come quicker, e.g. within days then within hours), * boot Windows (see more below) then Linux, then everything works again in Linux for weeks. Additional information: * for months, the bug was thought to affect only USB3 ports, it actually affects USB3 ports first, then extend to USB2 ports. Machine has 2 USB3 ports on the left, 2 USB2 ports on the right. * I have seen 2-3 times in months a temporary hang of the whole system (with audio still playing the last fraction of the audio in a loop), staying like this for about 20 seconds then everything becomes normal again even audio continues at the point it was. Not known if related. * In one episode of erratic hardware behavior I have seen at least one device still appear in lsusb after being unplugged. * The laptop is used daily with Ubuntu, put to suspend sometimes at night, seldom switched off. * 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. * Booting Windows fixes the USB problem! Just boot Windows then reboot to Ubuntu. All ports work again on Ubuntu, and work very well for weeks! * laptop has internal components which Linux reports like they are connected via USB. No problem observed with them. # Detail technical information lsusb output with no device in any of the 4 ports: Bus 002 Device 002: ID 8087:0024 Intel Corp.

Current kernel 3.11.0-20-generic #35-Ubuntu SMP Fri May 2 21:32:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux but bug has been happening for 6 months, so it's not specific to this kernel. # Possible duplicate * This may be the same bug #1132129 but I'm not sure so reporting here after reading https://help.ubuntu.com/community/ReportingBugs about duplicates . There are differences : #1132129 mentions crashes, which happened for months but no longer. #1132129 affected only USB3 ports not USB2. # Next step * Check BIOS version. Reference http://www.asus.com/Notebooks_Ultrabooks/N55SF/HelpDesk_Download/ * Test with latest upstream kernel as per the sentence "Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds ." * Test with Ubuntu 14.04 ? Thank you for your attention.
