Hi, I think that the problem is a little bit different. After some tests perhaps it is a problem related to the permissions of the file. The problem is present before that the OS is executed. I attach a screenshot that shows the problem and VBox.log.
Even if the screenshot shows you that are not present attached devices, there are some USB attached devices! VirtualBox can not access to some /dev or something else and do not show the attached devices! Please write me ifd I can provide you more information, I really would like to resolve this problem! ** Attachment added: "VIRTUALBOXBUG.png" https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1576768/+attachment/4660273/+files/VIRTUALBOXBUG.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576768 Title: user can not access USB devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1576768/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
