I wouldn't recommend the latter, because applying 5V (not 12!!) to the USB connector would probably supply the 5V line of the whole board, and I don't think this would do any good.
If you eagerly want to have the receiver of your remote steadily supplied, the only way is to supply the receiver permanently with an external power supply. Do as follows:
You need 1 USB extension cord and 1 power supply 5V (not 6V and not 4.5V, but exactly 5V, commonly not available in every warehouse, but at suppliers of electronic stuff - in Germany like Reichelt or Conrad) 500mA to meet the USB specs (the small ones fitting directly into the wall outlet will do).
Get the extension cord and dismantle 4cm in the middle of it. Locate the wires for GND an 5V (I don't know, which color they have - this may vary) and cut them in the middle. Connect the GND from the new power supply to both ends of the previously cut GND wire. Connect the +5V from the new power supply only to that end of the 5V wire leading to the end of the cable, where the receiver is to be plugged. Leave the 5V wire leading towards the PC unconnected.
Be sure to have the fresh connections well isolated.
Be careful to determine the correct wires - a multimeter will be of great help.
You are done!
Understand, that I cannot take responsability for any damage this procedure may cause.
I explicitly don't recommend this to absolute beginners in matters of electronic stuff. If in doubt ask help from a more experienced mate!
