Eth0 and USB with webcam disconnecting.

[JChen27]

What RPi? What OS? What kernel version?

Is your power supply beefy enough to drive your RPi and your webcam?

[JChen27]

I believe that my supply is handling it i do have quite abit connected on pi via 3v3 and 5v bars but the amp draw is minimal. It seems to disconnect and reconnect, I'm running a python opencv program and if I restart the program it connects to the webcam no rpi restart needed. If I cant figure out the issue I might just write into my main program to restart the python child process if it does not have an output.

I do have a 2 Variable Frequency Drives running off the same mains and I grounded the RPi ground pin to a ground bar that leads to the grounding of the mains. Maybe that is an issue? I can also try to unplug my keyboard and mouse and run for an extended period to free up some power on the usb ports.

4.9.28-v7+
2.4amp 5v power supply from Canna kit

[DougieLawson]

You shouldn't ground any part of your RPi to your household PNE earth or any ground spike. You could destroy your RPi that way.

[JChen27]

Where should the rpi be grounded to? Or should I leave the rpi grounds isolated.

[DougieLawson]

Don't ground it. Let it float. The ground plane on the RPi is zero volts relative to the 3V3 and 5V0 pins. The power supply doesn't have an earth pin because it doesn't need it.

[JChen27]

Without grounding it I am getting a lot of noise most likely from the motors and VFD's and my 1 wire bus fails to read, however with a ground the issue is not present.

[DougieLawson]

Then you need to find a way to suppress the noise from those devices without grounding the GND plane of your RPi.

I unplugged the HDMI cable and there is no longer sensor interference issues, I will test for an extended period of time and see if the usb disconnect persists.
