Is there an icon in the systray? Down by the clock? Right click it if there
is, see what you can do there.

I would focus on putting a switch on the lamp, not the port.
However, there is maybe a way... Check your motherboard
and/or motherboard manual for a 5V/5VSB jumper. It might be
called the wake-on-USB jumper or something to that effect
instead (though 5V/5VSB is the more accurate description).
Without that jumper in place, neither power rail goes to the
USB port. This is how it is done on all boards, AFAIK,
except maybe some of the more elaborate boards where Intel
fiddled with a mosfet or something (I forget the exact
details). Anyway, if pulling that jumper off disconnects
power, the rest is easy- Just get a 0.1", 2.5 mm spaced pin
header socket (like the ones that plug into the motherboard
front panel connector rows), 2 position with leads going to
a switch mounted wherever you want it.
Next of course is deciding where you want it. A round
switch is easiest, since you can use a drill bit (split
point type bits may work best) to make the appropriate sized
hole in the case, wherever... just be sure the switch is not
momentary as a lot of round switches are. I could go on
with mundane details about switches but it might be a waste
if you already know what you need. A couple examples,

.... or there's the typical toggle types but they look so
20th century. Some Toggles are a bit shorter though, good
for areas with little clearance while still having a
relatively sturdy switching mechanism.
Another switch option might be if your case uses the std.
(8mm ?) micro switches for power and reset. That is, IF it
has a reset switch you could swap out that switch with the
"Turbo" switch cannibalized from some old AT case from a
mom-n-pop computer shop. Takes more time, is cheaper, but
you loose the reset switch functionality.

If using XP find the port in device manager and disable it.z21 said:Anybody knows how to "switch" on/off an USB port?

I would think the lamp uses only the power from the port, not the data
aspect of it. Switching off the port probably would not do anything at
all. What I would have done, is buy a lamp with a power switch on it.
If you cannot find a lamp with a power switch, and you are good in
electronics, you can buy a miniature power switch from any of the
electronics parts suppliers. You would have to choose one from the many
types available to fit how you would like to modify the lamp.
I personally would not want to use a USB lamp. I would buy a nice small
independent desk lamp, instead of using a port on the computer for this
type of application.

Please don't toppost. Your answer belongs after, or intermixed
with, the material to which you reply, with non-germane portions
snipped out.
A possible reason for such a device is to get temporary lighting
during power failures, with the power source being the UPS (if any)
supplying the computer system.
