gouri, did this problem not occur in a release prior to Saucy? ** Tags added: latest-bios-207
** Tags added: kernel-bug-exists-upstream-3.15-rc5 regression-potential ** Description changed: - # Summary + 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. - 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.
