Seems that locating drivers for this USB TV Tuner is difficult now. Kaiser Baas does not seem to keep any legacy devices anymore and they no longer make TV Tuners.
My Google-fu didn’t seem to come up with anything either so I had to go on the hunt for the original disk that came with it nearly 10 years ago. Seems that this is now pretty rare? Luckily in a dusty CD case I was able to located it.
Anyway here are the files Kaiser Baas USB TV Tuner. This hardware is also 32bit.
