Remote USB switch

I have a high speed USB v2 widget which is a distance from my PC. I also run
different O/S (i.e. Linux) which don't like to see my widget and can cause
crashes. So I have to constantly plug/unplug my widget depending on what I'm
doing. I am concerned about the constant plugging/unplugging and the
mechanical wear/stresses on the connection - I have had a few memory sticks
fail as a result of this.

What I would like is a little circuit which sits in line with the USB widget
and I can turn it on and off via a simple switch. My first thought is
something like a tri-state bi-directional buffer with an enable facility -
or rough it and use a four-pole relay. Whatever, it must not interfere with
the data speed of the widget, so we are talking about something with a high
bandwidth.

Any ideas?
