Install the latest version of vbox in ubuntu 11.10 to solve USB, video, and other device Solutions

Ubuntu 11.10 installs the latest version of vbox to solve the problem of USB, video, and other device solutions. I am talking about 11.10, not other versions. After installing vbox, install the enhancement package, and then install the system in vbox, every time I open the vbox, I am prompted that the USB cannot be connected. Many posts on the Internet have many methods.
Most widely used: Add a user group usbfs $ sudo groupadd usbfs to www.2cto.com to view the gid $ cat/etc/group of the usb fs user group | grep usbfs: x: 1002: add the current user to the usb fs group $ sudo gedit/etc/group and change usbfs: x: 1002: To usbfs: x: 1002: joson to reset permissions for the USB device, edit the/etc/fstab file and add the following two lines, note that your gid may not be 1002 $ sudo gedit/etc/fstab. Add www.2cto.com #1002 is the USB group IDInone/proc/bus/usb usbfs devgid = 1002 at the end, devmode = 774 0 0 after restarting, you should be able to use the USB device in the client. I tried this method. No, it's wrong. Later, I used the following method: Open the terminal, enter sudo adduser xxx vboxusers xxx, which is the user name I have to log on to, restart it, and then add a filter from the device list in your vbox-settings-usb, you can see external devices such as the video header.
