Camera reconnection

Open alexandruradovici opened this issue 3 years ago • 3 comments

I am trying to disconnect and reconnect to a Alvium 1800 U-1620 USB camera. It seems that the camera returns error -12 unless I restart the application. I have attached a video showing the behavior in VimbaViewer. I am using Ubuntu 20.04 LTS.

yes this is my problem too. Sometimes though closing the program does not solve it and I have to disconnect the USB Cable and connect it again for it to work. Same issue in VimbaPython, if I connect the USB cable and run the example code asynchronous_grab.py. I get the frames. but if I run it again I get the error: vimba.error.VimbaTimeout: Frame capturing on Camera 'DEV_XXXXXXXXXXXX' timed out. I am using Ubuntu 20.04 in a virtual machine.

Hi, The above issue is because of the Virtual Machine because the VM takes more CPU performance and the USB drivers cannot communicate to the PC and causes the camera timeout. I request you to test it on a Ubuntu system running not from Virtual machine.

Thanks Arun Prakash

@arunprakash-avt Thanks a lot, yes using the camera without a virtual machine solved the problem.
