Description
Upgrading from 2.2.0 to 2.2.4 renders all USB support inoperable. After a reboot, VirtualBox reports this issue: {{{Failed to access USB subsystem.
Could not find the Host USB proxy service (VERR_FILE_NOT_FOUND). The service might not be installed on the host computer.
Result Code: E_FAIL (0x00004005) Component: Host Interface: IHost {926469ca-9091-42ef-928e-582d78b66c70} Callee: IMachine {13420cbb-175a-4456-85d0-301126dfdec7} }}}
The only way to resolve this is to attempt a repair install (not possible in the normal way, see bug 4206) and reboot. This may need to be done more than once.
Even after the USB sub-system has been recovered, USB functionality is not immediately available. The guest will not list defined USB items (i.e. they have filters) under "Devices/USB Devices" until the item has been attached to the host and the VB drivers installed again. After this the guest will need to be restarted from fresh to have the device work (see bug 3033).
