LIke said already: post as much info as you can. This is so minimal. Yet: try switching of USB 2.0 support. Does not work in the openSUSE version (not openSUSE’s fault, Oracle cripples the open version).

you have probably mixed versions of VBox and Extension pack.

soni_shrikant · January 13, 2012, 6:04pm

No both the pack and extention are of version 4.1
my operating system is opensuse 12.1
and i m using gnome3

That’s not enough precision. E.g
VirtualBox-4.1.8_75467_openSUSE114-1
Oracle_VM_VirtualBox_Extension_Pack-4.1.8-75467.vbox-extpack
virtualbox-4.1.4-3.2.3
Oracle_VM_VirtualBox_Extension_Pack-4.1.4.vbox-extpack
