"When installing the Presonus Firestation on Windows, "New Hardware Found" keeps popping up - is this normal?"

This is normal. The system is simply installing 3 sets of drivers: MIDI, WDM, and ASIO. If 3 New Hardware Founds does not pop up upon first installation, you will need to reinstall drivers. If 3 installations do not automatically come up, audio will not work, and you need to force it to install the other drivers. Luckily, it is simple to do this. Go to your MLAN control panel, check WDM, hit SET, uncheck WDM (forces it back in ASIO mode), hit SET, and it should find new hardware twice. Simply point it to the driver CD ROM for the drivers, and this should solve the problem.
