I might have a related issue - on my Win7 HTPC, I installed the drivers and updated to 3.0. The flirc was accepting configurations and everything looked like it would work, but when I tested it on a notepad file, the remote would not navigate or type the numbers 0-9, or do anything.
Finally I plugged in an actual keyboard (my normal configuration has NO keyboard installed), and the flirc immediately started working.
Please post back if your issue was resolved.
