9094,"'Failed to access the USB subsystem' error,  when accessing settings for an image and no USB devices",bikehead,,"My windows7 guest is running pretty well on my Fedora 15 host, but I cannot get Vbox to access any of my USB devices.  This F15 is a fresh install as is the VirtualBox rpm and the Windows 7 guest.

At guest start everything looks normal with no error messages.  However, when I use machine->devices->USB I don't see any attached USB devices.  When I access ""settings"" for the machine I get the following pop up:
  Failed to access the USB subsystem.
  Could not load the Host USB Proxy Service (VERR_FILE_NOT_FOUND). The service might not be installed on the host computer.
