There are only two prerequisites that need to be achieved for USB to work with a Linux host.

• 1) the extension pack must be installed How to install Extension Pack
  2) your user name must be in the hosts vboxusers group.

You must at least log off and in before permissions take effect.

This is also explained in your VirtualBox users manual

Ok, can you explain me to create vboxuser group on linux and to add my name with this group please ??

[KaneYukio]

I have find the way :

sudo apt-get install gnome-system-tools

Well done ! Thanks i will try if that's works.

In a host terminal run this:

Code: Select all

sudo usermod -aG vboxusers <your username>

Replace <your username> with the name you use to log in. Type your user password when prompted.


Be sure to log off and back in to finalize the change in permissions

Please help me, my account name is now on NORMAL and no ADMIN. I have lost admin power with my account !

[Perryg]

Can you tell me why this is? Why can you not use sudo to run elevated commands?

[KaneYukio]

Before typing command on terminal my account was ADMIN, now is on NORMAL i have lost ROOT and ADMIN account, i have typing a bad command on terminal, i don't now what append to my computer, how to change my account to ROOT please ??

[Perryg]

Well you must have made a mistake in typing. But you can recover the root password from the recovery console if that was changed, or you can also fix your login from there. Here is a help link to get you started. http://askubuntu.com/questions/24006/ho ... t-password.
If it is just your login then you can find your user ID and add it to the admin group by using the same information I gave you before. Just be careful this time and type it exactly as shown. Linux is case sensitive so you must be sure.

Hello, i have worked hard to rescue my account but it is okay now, i have write this in the shell in recovery mode :

mount -o rw,remount /

ls /home

passwd

addgroup admin

adduser ***** admin

Thanks you for your help virtualbox works fine with usb.

I have lost my admin account with a virtual chinese livecd (win xp) and not with a bad typing in the shell.
