Jim Weirich wrote in to say that he has it on good authority that the KeySpan USA-19HS will properly drive a Firecracker. The Keyspan adapter comes with Mac OS X drivers that speak the handshake signals the Firecracker listens for. Huzzah! That means you can remotely control your lava lamps from your Mac.

Enjoy!
