no chance , i tried everything, different OS versions (XP SP2, SP3), different firewire-drivers (from SP1 to vista etc...) , all drivers from Focusrite-website (up to 1.4beta) , different FW-cables and adaptors , but i didnt get it to work. Sometimes it crashes, sometimes it does not appear as audio-device, but i didnt get any sound out of my Saffire-LE under Bootcamp-Windows on my new 2009 Mac-Mini.
Under OSX it works without any problem.
I contacted Focusrite , but only got "it works under Windows, read our FAQ"...
What more can I do ?
