 mode of operation
 =================
 
-an NOR-gate-based SR-latch is used.
-the RESET button triggers the R signal to reset the latch.
-when a USB cable is plugged, power is provided by the battery to the cable.
-if an integrated circuits is present, current will flow through.
-a 1 k Ohm resistor on the low side (e.g. ground) will create a voltage.
-if the plug draws more than 1.6 mA, the resulting 1.6 V will trigger the S signal to set the latch.
-the BUG LED will indicate when the SR-latch is set.
-the latch remains set until the RESET button is present.
-thus, even if the plug stops drawing power, the LED remains on.

-this minimum 1.6 mA current draw is often caused by the decoupling/bypass capacitor required by integrated circuit, or accompanying voltage regulator.
-when charging, the capacitor acts as a short for a small time, allowing current to flow.
-on USB plugs with just resistors, or LEDs, the resulting current flow is not large enough.

-because of the 1 kOhm inline resistor, and limited 3.3 V provided by the battery, a maximum of 3.3 mA can be drawn by the USB plug.
-this is often not enough to power up integrated circuit properly, particularly if they use a radio interface.
-thus it is safe to use the USB bug detector on bugs, without activating it.
