USB Question

I just installed the homebrew channel (off a SD card) and was wondering if I need to keep it in there? I have a 8gb USB stick I wanted to us but not sure if you can load channels and stuff from it.

Do I need to keep the SD card with all the files from the install in there? Or and I switch to USB now?

You can run homebrew from a USB stick if that's what you're asking.

You dont launch channels off either SD or USB. You don't need an SD card in to load HBC if that's what you want to know.
