Hi Eddy, sorry I’m an old guy so don’t fiddle with shields or anything but will try whats’ been suggested.
All I know is if I uninstall Avast everything works great which is what I have done on the laptops.
On my development desktop PC I’ve got Avast in Passive mode.
Yawcam btw works tottaly different to any other webcam app in that it uses Java as it’s GUI.
I develope in C++ for over 30 years now and every program I’ve written for webcams do not work unless I remove Avast.
I did try AVG before I made any post but that too did not work.
I’ll just wait till Avast fixes the problem then I’ll enable it again.
Oh btw as I said, I use Win7 Pro 32 bit + Sp1 with all latest updates on all computers.
** Edit **
Ok I tried the Shields and with all 4 turned off and a reboot, the problem is still there.
I do not know how to disable the ‘usb checking’ as you suggested.
Btw, I’m running Avast version 2294 but the problem was there with 2291 also.
