That sounds to me very much like an electrical problem rather than an electronic
problem. Your USB enclosure device is creating a ground loop or a short that
is causing your modem to disconnect. Your modem is apparently the only device
that you have that is sufficiently sensitive to be affected by this.
Try switching the modem to a different electrical circuit and see if anything
changes. (Note that "different circuit" doesn't just mean a different plug-in
in the same room as they might be on the same circuit.)
My next step, were I you, would be to call an electrician and have him check
things out. Aside from the inconvenience, something like this could also be
hazardous to your house and your life.
I know this is usually used to refer to DC circuits, but you can run
into problems if the phases on an AC circuit are reversed on one or
more outlets. I don't know if you are using grounded outlets, but if
so, make sure you have a good ground. In the US, they sell cheap
circuit testers with 3 neon lights that tell you right away if you
have an outlet wired wrong. Well worth the $2 price.
