VirtualBox USB subsystem: KDE racist bug

[Shunyata]

Hi,

when I start VirtualBox (4.0.8 r71778) I get

Failed to access the USB subsystem.
Could not load the Host USB Proxy service: VERR_DISK_FULL.

Result Code: 
NS_ERROR_FAILURE (0x00004005)
Component: 
Host
Interface: 
IHost {…}
Callee: 
IMachine {…}

But this only happens on KDE. When I enter the same VM's settings in Gnome it works fine. Does anybody have any idea why this happens? What does VB require, which isn't available in KDE? Also: What about the expansion pack? It doesn't seem to be in the Oracle repository. Do I really have to install it manually after I installed VB PUEL?

Thanks in advance.

Best regards,
Shunyata

yes, just download the files and install it from the GUI or via command line

VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.1.6-74713.vbox-extpack
