Checking for VL805 (Raspberry Pi 4)...

  • It seems that you don't have VL805 (Raspberry Pi 4).

There should be no problems with USB (a.k.a. select() timeout)

It doesn't look like it's seeing the camera as a video device.

SSH to the Pi and run lsusb and see if it is listed, first

Hi Charlie_Powell
this is what came up from lsusb command:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Please note that:

  • the webcam is attached solely to the raspberry pi via micro-usb
  • there are no other power source to the cam
  • the Raspberry Pi Zero 2 W is connected to the Prusa MK3 via solded pins
  • the cam is working just fine when connected to my notebook
  • between the raspberry and the webcam I attached an adapter USB Micro B male to USB A female

Can I do anything differently?

Thank you again for the help.

Just to make sure, you actually attached the cam to the USB data port, not the USB power in port?

You nailed it. As simple as that!
Tomorrow I’ll switch the port and report the follow up.

Thanks to all.
Ciao

Hi Foosel, you were totally right.
I was mistaken with the USB port.

Thank you again. :wink:
