There apparently are
USB Quickport inserts. All you would do with these is assemble them with M-M USB cables and a
Quickport box or wall plate. The boxes and plates come with 1, 2, 4 and 6 ports. You can also get various other types of inserts and blanks.
This is the closest I think you will get to a "pre-built" solution for this, the only downside being it's not very cheap.
