I'm using the latest version of both Virtual Box (4.1) and CentOS (6.2). I would like my Western Digital USB drive to be recognized by my VirtualBox guest operating system.

My host system, Windows 7, recognizes it. It is also recognized when I open the settings of my VM. I've checked both Enable USB Controller and Enable USB 2.0 Controller and I've installed the Extension Pack for Virtual Box.

But when I launch the VM the USB devices icon in the right bottom corner shows "No USB Devices attached" and, of course, no USB drives are detected by CentOS.

  • Does grep usbfs /etc/fstab or mount | grep usb return anything?

  • Haven't got the time right now, but try googling for usbfs, CentOS and VirtualBox... (maybe this?, without the remount)

    @MilesM. can you post it as answer to your own question? How did you know which type of usb-port it is?

I found the answer :

It was because i've plugged my usb 3.0 usb drive on a 3.0 port, and that was he probem, VirtualBox doesn t seem to recognize 3.0 usb drives. but when I put it on a 2.0 usb drive, It works !
