Here is what I am trying to accomplish:
I have three rooms in my house (living room, bedroom, basement) that have tv's and I want to be able to have each set up such that all I need to do is bring just the wii (nothing else) to a particular room, hook it up, and play. I already have additional power supply's, wiimotes, IR sensors, and a/v cables in each room. The only problem is that i have one USB hard drive in my living room that has all of my wii games/apps/emu's/etc. on it. Running cable through the wall or in the basement to each room is not a problem. The only problem is the length limitation of the USB cable (max =15 feet). I have a manual USB switchbox to switch from room to room.
Ideally, I need to have a way to hook a USB hard drive up to the wii from a length of around 60 feet way. The usb/cat5 extender adapter works great but as discussed earlier, it acts as a USB hub, and as a result I can't use it to load anything from a cios. Moving the hard drive every time i wanted to play in a different room would be to cumbersome and not really worth it since it has its own usb cable and a power supply plug which are neatly tucked behind my tv stand.
