BackTrack 5 R2 – VirtualBox Guest Additions + USB Issues Fixes

VirtualBox is of course the most suitable virtualization solution to run BackTrack. Unfortunately, with this latest version of BackTrack, the VirtualBox Guest Additions cannot be installed on a fresh new install. Fortunately after some modifications, everything can be fixed to compile these additions for the 3.2.6 Linux Kernel of BackTrack 5 R2.

Download and Install

If you want support for USB 2.0 devices you must download and install Oracle VM Extension Pack for VirtualBox!
I will not describe the steps to install BackTrack on VirtualBox. A lot of tutorials can be found on the Internet to upgrade to BackTrack 5 R2 or to makea fresh install. But here are some screenshots about the VirtualBox configuration for my MacBook Air i7 1.8Ghz.

Issue #1 (solved): USB device descriptor error

usb 1-1: Device descriptor read/8, error -110
usb 1-1: Device descriptor read/64, error -110


Number of Processor for the Guest OS must be set to 1 or eventually 2…
For example, my MacBook Air has a Core i7 inside, multithreading displays 4 virtual cores. So I have to set a maximum of 2 cores to BackTrack VM Guest to fix this issue. (Even if the recommended number of cores VirtualBox displays is 4).

Issue #2 (solved): VirtualBox Guest Additions

When you try to install the VirtualBox Guest Additions, these two kinds of errors can occur and lead to a vboxguest kernel extension impossible to load.

The headers for the current running kernel were not found. If the following module compilation fails then this could be the reason.


Building the main Guest Additions module …fail!
(Look at /var/log/vboxadd-install.log to find out what went wrong)

Both issues result to:

Starting the VirtualBox Guest Additions …fail!
(modprobe vboxguest failed)



apt-get install linux-headers-$(uname -r) linux-headers xserver-xorg xserver-xorg-core file-roller # file-roller is not needed, but recommended
cd /usr/src/
tar jxf linux-source-3.2.6.tar.bz2
cd /usr/src/linux-headers-3.2.6/include/
rm asm
ln -s /usr/src/linux-source-3.2.6/arch/x86/include/asm asm
cd /lib/modules/3.2.6/
ln -s /usr/src/linux-headers-3.2.6 build

Ready to install VBOXADDITIONS 🙂
