Many thanks Martin. Trawling through the linux-usb and distro kernel mailing list archives shows that the kernel blocking problem has been around for some time and discussed at length.
What it seems to boil down to is this: https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/tree/drivers/usb/core/hub.c#n67 The fact that parameters exist to force or fallback to the old initialisation scheme indicates the kernel devs. are aware there could be problems with the way USB devices are initialised, depending on the USB device. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1546641 Title: unity-settings-daemon crashed with SIGSEGV in up_exported_daemon_get_lid_is_closed() To manage notifications about this bug go to: https://bugs.launchpad.net/upower/+bug/1546641/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
