My host OS is Ubuntu 15.04 and my guest OS is Windows 10. I'm running VirtualBox 5.0.2 r102096.
When the guest OS is running in the VM, right-clicking on the little USB icon displays a context menu with a single disabled menu item that says No USB devices connected.
When the machine is powered off and I go into its settings, on the USB tab, the Enable USB controller option is checked and USB 3.0 (xHCI) Controller is selected. In the USB device filters list some of my previously created (from when it still worked) filters are present and when I right-click there and select Add filter from device, I am greeted with a similar context menu with a single disabled menu item that says No devices available.
My USB flash drive is inserted into the host computer, but other devices should be visible as well, namely the integrated webcam, the touchscreen and stuff. They were previously, before either upgrading Ubuntu or upgrading VirtualBox, I cannot pin point precisely when it stopped working as I run the guest OS sporadically.
When I run sudo adduser tomashubelbauer vboxusers
, I get The user tomashubelbauer' is already a member of
vboxusers'. When I log out and log in again, the same thing happens.
Are there any other knows issues with VirtualBox being unable to enumerate USB devices? Are there other options for me to troubleshoot the issue further?
