I know your situation – I tried virtualbox-ose-3.2.8 (~8 yeras ago) and
it's still running on my ancient workstation. Simply works for the one
XP I need to have arround for some of the named reasons.

Regarding USB-related requirements, I always found a device which made
trouble – even with ESXi's generally very well working USB passthrough.
So I use a USB-Device-IP-bridge.  The one I import from USA to Europe,
because of it's yet problemfree design/hardware/(Win-)software, can be
found for ~US$55.- if you search for ID-DS0611-S1 – might be out of
budget for private use though...

I'm very curious about the workaround avg@ posted.
For all server virtualization tasks I switched to bhyve(8) half a year
ago for my local office.  It simply works (for FreeBSD + Win2012R2
guests) and I'm happily finding workarounds for current limitations in
favour of having a bare metal ZFS storage subsystem in parallel to the
hypervisor :-)

Thanks to all coders for this nice OS extention!
