Here all details (dmesg, lspci etc): https://bugzilla.kernel.org/show_bug.cgi?id=94261
The machine is: LENOVO 90BX0018IX/Aptio CRB, BIOS O07KT49AUS 12/18/2014 OS is a Debian Wheezy amd64. The issue is that USB ports work only starting the kernel with "pci=noacpi" parameter. Without it, nothing plugged into usb ports is detected. In particular, "lsusb" returns "unable to initialize libusb: -99". The same happens with a 3.13.11 kernel (same config). I've tried newer kernels (3.18.8, 3.19) and they show the same issue. With the difference that, with "pci=noacpi" they don't start at all. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
