You can't. It needs the MBox2 interface.
Pro Tools LE (up to version 8.0) will only work with Avid (Digidesign) hardware, ie. MBox, Digi 002, 003 etc. Pro Tools M-Powered works with approved M-Audio USB and Firewire audio interfaces, not the USB microphones. It is not possible to use multiple USB or Firewire audio devices in Pro Tools LE or M-Powered.
I think the best recirding software is Pro Tools LE
I think it needs at least Vista. Check from the manual.
