Hi I have been running W7 Beta w/ an Edirol FA-66 firewire sound card with great success until the Beta expired yesterday. The key to making the Edirol sound card work was to go into Device Manager and select the Legacy firewire driver. I since installed W7 RC and the legacy firewire driver is no longer an option. Where did it go? The button to roll back driver is grayed out. If I try to search for drivers it just tells me I have the latest driver installed. This is no good since the latest firewire driver does not work with the Edirol (or PreSonus for that matter). HELP!
