[efh] USB storage device workaround

[Drake Wilson]

The reaction between the Windows bogosity of "installing" drivers
whenever you attach a new device and the UT IT (semi-)bogosity of
locking down the machines as tightly as they do seems to fill the
ACTLab with an explosive and sulfurous gas every time anyone wants to
use USB mass storage devices on the Windows machines in the ACTLab,
causing much strife thereby.

It might be possible to work around this by acquiring and connecting
transducer devices.  Each such device would stay permanently connected
(thus avoiding the driver loading issues), speak USB mass storage
protocol to the computer, and claim to be a removable disk drive of
some stripe.  The "medium" that the "storage device" would take would,
however, consist of another USB mass storage device on the other side,
with insertion and removal being mapped to appropriate "medium
present" and "medium not present" signals, and such.

Drawbacks would of course be the resources expended on finding and/or
building such devices in the first place, and then on keeping them
connected.  You'd also still have trouble if you wanted to connect
more than one "real" USB mass storage device at a time, unless you
wanted to find/build twice or thrice as many transducers.

Any Extreme Freestyle Hackers with more hardware knowledge than me
feel like picking up the baton on this one, or partially picking it
up, or something?  Interns?  Anyone?  :-)
