Description of problem: There are several reasons why a plugged USB device may fail to enumerate: - Exhaustion of xHCI resources (see http://plugable.com/2015/09/08/not-enough-usb-controller-resources) - Not enough power on the bus - Not enough bandwidth of the bus - Broken/buggy device Right now, the device will silently fail, leaving the user confused. An advanced user will know to look at journalctl or dmesg, and browse the text logs for clues. The kernel should have a notification mechanism for USB and other device failures, and this should broadcast in a structured way to interested user clients. It is possible that udev could emit events for dead devices plugged into a port. Once the kernel has such a mechanism and drivers are modified to support it, the desktop environments should be extended to notify the user when a device is malfunctioning. I've assigned to gnome-desktop3 but this is a more general problem and should be handled in all desktop environments. Probably a bug for each environment should be made. There are also kernel and driver changes needed as well. Version-Release number of selected component (if applicable): gnome-desktop3-3.18.2-1.fc23.x86_64 How reproducible: Always. Steps to Reproduce: 1. Plug in a broken USB device, or a device that uses too many power or other resources. Actual results: Silent failure. Expected results: A user notification with a recommended course of action. Additional info:
Note that USB-IF has an explicit policy around this kind of thing: http://compliance.usb.org/index.asp?UpdateFile=Embedded%20Host&Format=Standard#10 "No Silent Failure"
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.
