Can’t use the USB ports on Virtual Box

Asked By Alexander Stevens 20 points N/A Posted on - 06/24/2011

Hello,

I installed Virtual Box on a PC running with Windows 7. Unfortunately, I can't use the USB ports on the machine guest (Windows XP).

In the configuration of the virtual machine, I turned on the EHCI controller for USB 2.0, but when I add a USB device filter (+ button), UBS no device is available, while a USB Drive connected to the PC.

I tried everything I could read in the documentation of Virtual Box, but there must be an installation error somewhere.

I therefore appeal to you to find a solution.

Thank you.

• ln -s .usbfs/devices /dev/bus/usb/devices
• mount –rbind /dev/bus/usb /proc/bus/usb

3. Change it to this:

• Magic to make /proc/bus/usb work
