Yeah they certainly haven't made it easy on us. And they have responded with, "We're getting to it" since the beginning of AS3. Thanks for sharing.
As a matter of fact that's the main "seriously Adobe?"

You are not alone there. I think one of the things preventing this from getting implemented was that nobody speaks up about it, they just move on. Hopefully this lights a fire under them to get it done.
Keep in mind that this is only for AIR at the moment. I'm sure there is a ton of security they would have to look into for something that looks for USB input for web-based Flash.
