Remote access to an USB drive

I purchased recently a MV-4000 Mvix Media Center from newegg.com. This is Mvix’s lowest end product and the cheapest you can find. It lacks Ethernet connection in favor of USB connection. At the beginning it looked like a good deal, but the hassle of moving the device back and forth between the living room (where the TV) is and computer room became annoying.

So I start looking for ways to access this device remotely, without disconnecting it from my entertainment center. Until now I found the following solutions:
