Just thought I'd share this with everyone. I spent a good few hours this morning trying to get the latest firmware to download to my Hyperion charger. When using their firmware upgrade tool, the trick is to hit the "Program" button when there is no power applied to the charger. As soon as you see the firmware upgrade tool waiting for the hardware to reset, power up your charger. The firmware upgrade will then start.
I spent a good deal of time uninstalling/reinstalling USB drivers, then trying many different laptops. Hopefully someone else can use this information and save a whole lot of time.
