I tunneled the USB device to it:

That works fine... until I have to go into the office. Once I
disconnected the USB go away for 10 hours and come back, it
fails to re-engage. The USB seems to get grabbed up by the
laptop itself instead of the VM. The only way to get it to
work again is to halt the VM and do a cold boot of it. This is
annoying to say the least because I lose 'state' when I boot,
ie the set of windows and files open that remind me of where
I left off on a project before going to work.
Any suggestions how to get around this annoying issue?
I could be wrong. But I believe you want managed='yes' so that libvirtd
detaches the device from the host automatically.
