Some more observations: - saving "on" and "auto" to /sys/bus/pci/devices/0000\:00\:14.0/power/control result in the same as reloading xhci_hcd module - blinking of mouse led light and latency switch messages in dmesg Created attachment 132191 [details]

Hello, with new version of Lenovo BIOS - 1.66 - problem is fixed. Thank You. |
Created attachment 132181 [details] dmesg, lsusb, lspci outputs Symptoms: USB ports stop working (power off) just after boot loader loads kernel. Observations: - with acpi=off this doesn't happen - USB ports are turned on - in Windows usb also work - regular boot, removing and inserting xhci_hcd module result in few seconds of switching usb power on and off (observed on connected optical mouse) and after that remains off (several "xhci_hcd 0000:00:14.0: setting latency timer to 64" messages in dmesg) - when laptop-mode-tool is active, switching "tunable" in powertop of USB xHCI controller to "bad" and back to "good" results in turning USB ports on stable, recognition of mouse device and starts working - does not depend on arch (i686, amd64), firmware (bios/uefi), kernel version (tried 3.11 and 3.14 in openSUSE 13.1, 3.2 in Ubuntu 12.04) - tried on live usb stricks of these distros Configuration: HW: laptop Lenovo ThinkPad Twist 3347-26G, BIOS v1.65, Core i5-3317U Ivy Bridge SW: as is written above, do not depend on distro or kernel version. For testing, I am running OpenSUSE 13.1 with kernel 3.11.10 My questions is, since it is somehow SW related, where I can look for some log of changes made that lead to turning usb power on? How I can enable some more verbose logs? But anyway, I will appreciate any suggestions what to try to discover what is happening and how to resolve it. Thanks
