+	   Some devices need to draw power from USB when they are

+	   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.
