Do you mean Homebrew Channel?
If so what System Menu are you currently running?
Also what will you be using the Channel for?
This guide is what you need
Nintendo Wii 4.3 Softmod Guide
If you ever update your Wii to a newer System Menu (won't be for ages yet) you will probably have to re-softmod your Wii. But there will probably be no point it upgrading anyway.
As for loading games via USB I suggest using WiiFlow![]()
