I couldn't find the answer anywhere, so I called Startech. They said "they would get back to me" regarding Win7 64-bit compatibility. They never did, so I took the leap and bought it anyway. Bam! Worked first time out. I got this USB adapter because it has an optical Toslink IN, which is rare on a device like this. I'm transferring over old DAT tapes to WAV files.. and this works just handy-dandy-perfectly with my Win7 old DAT machine. Cheap, works, excellent.
I've installed many cards in many computers. This card does not work correctly period. Tech support is horrible they keep asking me do do the same thing you have to do any time you install any card. The card is cheap and you get what you pay for.
