I-O Data GV-USB2 not working on new PC/Win 11

I cant get the GV-USB2 to work on my new pc. The device shows up in vdub but when I select it, I get an error popup that says that virtualdub cannot connect to capture device drivers.

Ive tried both the current and previous version of the drivers, and different versions of vdub and vdub2 but no joy.

I have enabled camera in privacy settings.

The dongle shows up in device manager and in vdub but for some reason vdub just cant connect to the drivers.

This briefly happened when i first tried to use it with my old pc but then it just started to work for whatever reason.

Luckily I still have my old pc that I can use for capturing, but its a bit of a ball ache transferring the video from pc to pc so I want to be able to use my new one for capturing.

Just wondering if anyone has any ideas?

You may have already tried any of these:
- unplug / replug the dongle
- reboot the PC
- in Vdub select device 0 Microsoft WDM .....
- Use AmarecTV instead of Vdub
- Download and install VirtualVCR and configure from there

Yes already tried 1st 3 suggestions with no success. I havent tried AmerecTV and VirtualVCR though as I want to be using capture software that has a histogram.

Yes its turned on.

There is a special switch for DESKTOP apps which must also be ON

Ive had that turned on as well.

The working driver I am using with W11 is
1.1.0.93.5, 2010.06.28

Good call, thanks. I tried it on the usb 2 port on the back and it works . Strange though as Im sure that it works on a usb 3 port on my old pc.

Yes, my works on USB 3 here. I recall a poster saying the USB 2 standard was rigorously applied, whereas USB 3 has become a bit of a free-for-all.

So it was an under voltage issue hehe. (Card detected but not enough juice to actually work) What can i say, not surprised. I've always avoided usb cards and lived happy. Actually i lie i got an hauppauge Nova-T (Dvb-T) working daily for + 10 years now. Must be a world record.
