How to identify USB failure in VMVirtualBox in Ubuntu

So the first time I used USB, I found that I could not recognize it. After searching online, I finally solved the problem.

I have installed a VM VirtualBox in Ubuntu and an XP operating system in VM VirtualBox. Because sometimes I need to copy files in XP through a USB flash drive. So the first time I used USB, I found that I could not recognize it. After searching online, I finally solved the problem. [LINUX community www.LinuxIDC.com] the solution is published as follows:

Go to System> Administration> Users and Groups-then "Manage Groups", then:

1 double-click "vboxusers" then check/enable your account in there, OK.

2 Click Add> enter group name: usb, group id: 85, add your account in there too, OK.

3 Restart your computer.

Okay, it's that simple. Don't believe you can try it yourself.
