ATI 750 USB crossbar gone?
 

Been using the ATI 750 USB for years and even successfully moved from Windows 7 to Windows 10 on it. Last week though I was using it and got a BSOD as the unit fried on me.

OK...so I found a replacement for cheap because this has worked well for years and I use graphstudionext for it.

Got the new one plugged it in and...the saved graph I had won't work because the crossbar ("AVStream Analog Crossbar") doesn't find a device. As a matter of fact I don't even see one to add in the filters.

I even went to another win10 machine and followed my own instructions for how I got the first one to work and still have the same issue.

Does any of this make sense? I still have the ksxbar.ax file.

The 750 is a known-bad card, multiple issues, especially overactive AGC.

Windows treats almost all capture cards like webcams now, especially Win10 and Win11. So for capture cards to not work properly, or at all, is the new normal for at least 5 years now. So many cards have stopped working with each new Win10 update (as each "update" is more like a whole new Windows, not just a small update).

Did you upgrade from Win7 to Win10, when the card was working on Win10? It's an old trick to install something on an OS, and then upgrade the OS, and it still works. But natively, it will not install correctly, or at all. I've not seen this done much since the 90s-00s, but I know it still works.

Or perhaps you just need a new installer disc? Perhaps the CD file is corrupted enough to not work, yet not corrupt enough to open/run from the CD? I've see that.

So you were right there with this!! I had indeed upgraded that machine, which explains why the new machine wouldn't work. Doesn't explain why this one quit, but that's beside the point. :)

Found this post which made sense.

Went to the new machine, deleted the device (Cali TV Card??) and then set compatibility to XPsp3 on the 64 bit driver setup on the CD and ran it as administrator.

And I'm back in business!
