Tevion USB capture card not recognized? (USB 2861) - The Digital FAQ (2025)

03-27-2021, 10:50 AM

Hi,
I have installed the "eMPIA-Driver(Tevion)" driver provided by lordsmurf, but still after installing the driver, the card isn't recognized on Windows 10. In device manager, I see it is unrecognized as "USB 2861 Video". How do I fix this?

Thanks

This is on Surface Laptop Go by the way.

anyone? lordsmurf will you respond?

Mine is recognized but skips chokes and pukes. Thanks Bill Gates.

I just scored what I believe is a coveted Tevion and the video looks great using a lappy with older W10 on it.
Audio is another thing. Skippy stutter, but audio capture preview is off but I can hear it.
I’m looking through threads for ideas.
At the very least this laptop will be non-internet. No fatal updates.

Clean up thread some...

I have no idea. I know the video hardware and software, but not about every possible computer config out there.

To some degree, you're going about the al wrong. Connecting a video capture card isn't like connecting a printer.

Laptops are usually weak.
And something like a Surface is among the weaker of the weak, barely better than a netbook or tablet. It's meant to be weak, light duty, to extend battery life. OS settings are tuned to cut corners, to help with this. The side effect is that meatier tasks (like video) doesn't always work correctly.

You can capture video on a laptop -- I have a high-end Dell (M6800), and do it all the time. But sometimes that requires tweaking the laptop hardware/settings, so it's not strangling the process.

I confirmed this is a clone. Nice find.

So what you're adding to this thread is this: this card is known to work with Win10 on laptops. That's good. That's expected.

The audio issue is simply related to drivers and VirtualDub setup.
Did you use my driver zip/instructions for it?
I'm about to setup Win10 on a system, but not done yet. I can help folks more when I get my new dev box setup.

VirtualDub2 is almost always the wrong choice for capturing.
Almost.
All rules have exceptions.
The card works better in VirtualDub2. So try it. You still need to do some tuning to the timing settings, but VirtualDub would sometimes completely reject the card's audio input (especially on WinXP).

I have captured on much slower and older laptops with no issues. There doesn't seem to be anyone here that knows much about this issue. If you don't know either, the $90 capture card I bought from you will be a total waste.

Older and slower laptops (1) didn't have Win10, (2) didn't have the same sort of hardware-crippling to save battery life. In ye olden days of laptop, it was about newer and newer batteries to stretch life, not so much about crippling. If you needed longer, you bought extras (including some 3P). Once upon a time, 2 hour battery life was awesome. Now, if you get less than 10, people get out the pitchforks. That Surface Go has 9 freakin' hours, 5-6 under "load" (surely still crippled), and people poo-poo it because of it.

"USB 2861 Video" is the correct driver. It uses the eMPIA generic driver.

I don't know what "I see it is unrecognized" means. If it sees "USB 2861 Video", then it's recognized.

Device manager shows it as "USB 2861 Video" but with a yellow exclamation mark, so the card isn't actually recognized in Virtualdub, Virtualdub2, or any other software.
