VirtualBox USB enumeration error solved in fedora 40

When opening virtualbox first time in linux you might see a pop up message like

USB enumeration error




This fix will probably solve a lot of the problems you might have with VirtualBox 7.0. For your user to do a number of things with VirtualBox, it must be a member of the vboxusers group. Unfortunately, the installation of VirtualBox 7.0 doesn’t add your user to that group, so you have to do it manually.



Fortunately, this is simple. Open a terminal window and issue the command:

sudo usermod -aG vboxusers $USER

Log out of the desktop and log back in. Start VirtualBox 7.0, and you should see those errors have vanished.
