(Sorry for top-posting; I'm on my phone)

I suggest you to use Unetbootin.
This utility let you transfer almost any LiveCd to a usb key and make it bootable. Please note that sometimes it doesn't work on first try.

On this website, in the download section, you will be able to find a selection of livecd. If you use my PCLinuxOS remaster, all the needed firmwares are installed stock. Probably on the Ubuntu livecd too.

Good luck!
