I'm finally going to upgrade to Windows 7. My son recommended that I check first to see if the drivers for Presonus Firebox are stable. I couldn't find much of anything on the internet to say one way or another. Do any of you have experience with this and and what is your opinion? Thanks!

I see this is an old post but I just did this upgrade last week.  Figured someone else may take comfort in my reply before undertaking the PITA of an upgrade with all the uncertainty that comes bundled with it.   Anyway...  So far, so good with my old presonus firebox and windows 7 playing nice together.  Using asio drivers.
 
Cheers,
 
Gil
