The Google Stadia online gaming service is shutting down, and Google have released an update to the game hardware controller to enable it to be used as a Bluetooth device with other platforms. See: https://stadia.google.com/controller/index_en_GB.html Basically, you plug in the controller on a USB port, Chrome detects it, and asks you to proceed. However, on trying to do this I get an error message: Couldn’t connect to your controller because it’s currently being used by another tab or program. Close any tabs or programs using the controller, then try again. Of course I'm not aware of running anything else that could interfere with this, but just in case I repeated the process on a clean account with no extraneous processes and it made no difference. How can I discover what is accessing the USB port? I can see the device details from dmesg but that doesn't translate directly to a /dev file so I can't use fuser on it. poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
