Hi Sures,

Thank you for the reply. As I suspected, the problem is in the Windows 10. I've checked briefly all apps running in the background, but could not find any that use the camera. I need time to check the Win services. I'll do it sometimes later. I do not have much apps installed in my Windows 10. It is dedicated to the robotics with ARC, OpenVINO, MS Visual C++, Python and Java. Plus antivirus app and some Win tools for maintenance. Do not surf the Internet for anything but robotics. The ARC works well with EZ-R humanoid head camera and I am spending most of time on it. Regards

This issue has been gone over by better brains then I. However I have a couple "Shots in the Dark" if your are still up for it. I think it may help to try these in order:

*Try turning off your antivirus protection. See if that helps. Keep it disconnected when testing ARC for now. I know, dont worry. Just don't visit any unknown web sites while you have it turned off.  If you find this to be the issue try using Windows Defender for your antivirus needs. It's free, fast and stays updated. I switched a couple years ago due to DJ's suggestions and have never looked back.  *Make sure your project is saved and in a safe folder, then uninstall and reinstall ARC. *Reboot your computer. *With a new and empty project after the reinstall and reboot, try installing just the camera control in the empty project and try to connect to your camera. *Try different USB port on your computer. *If you are brave enough you can go into Device manager and uninstall and then reinstall the driver for the camera. With the camera plugged in you may be able to find it under the Universal Serial Bus Controllers. Here's a tutorial that seems knowledgeable on how to easily do this:  https://www.addictivetips.com/windows-tips/uninstall-a-usb-device-windows-10/ *Start at step one again and try everything one more time. Ugh. *Try using ARC and this camera on another computer.

Let us know if you try any of this and it helps. Have fun and happy building!

try and plug camera into another computer and install ARC

Thanks guys for the suggestions. I already tried with antivirus disabled, did not work. I installed Windows 10 on new HDD. Did not update it. Installed .NET and ARC. The USB camera worked fine.:D Updated the Windows. The camera still working fine.:D Some other app installed on previous Windows is the "culprit". Will find it.

Phew - that’s good to know. Thanks for the deep dive to resolve the issue, Gale. We were a little panicked on this end wondering what could be the culprit. I was slightly concerned ARC was doing something wrong but none of our tests could replicate the issue.

We are relieved over here

I vaguely remember years ago in the deep recesses of my bad memory that ARC (then ARC) was having connection issues when VLC was installed also. I may be totally wrong about VLC being the culprit back then. It may have been some other program entirely but it was a video editing program if I remember correctly.

If you are able perhaps you can uninstall VLC and see if that make a difference.

i remember that you have to delete averything from that camera . files are in diff places then reboot . folder on C : files in dowloads page . all files in device manager from that cam .

The culprit has been found!xD As it is written: the culprit is the list suspicious! It was the KeyScrambler Personal app ( protects everything you type from keyloggers by encrypting your keystrokes at the keyboard driver level, deep within the operating system). Spent a lot of time uninstalling apps and checking the camera until I noticed the KeyScrambler "hiding in the corner" When I removed it, the ARC was happy with my USB camera.

I could not select all of you from the "This was resolved by:" because all of you helped me to fix the problem. Thank you very much to all of you. I am very happy to be with you!:D
