+ Some devices need to draw power from USB when they are
+ configured, perhaps to operate circuitry or to recharge
+ batteries. This is in addition to any local power supply,
+ such as an AC adapter or batteries.
+
+ Enter the maximum power your device draws through USB, in
+ milliAmperes. The permitted range of values is 2 - 500 mA;
+ 0 mA would be legal, but can make some hosts misbehave.
+
+ This value will be used except for system-specific gadget
+ drivers that have more specific information.
