Steps to reproduce

  1. connecting two cameras and trying to use them

Expected behaviour

  • there should be two streams that should work

Actual behaviour

  • only one stream work and I get this error for the second camera in the logs Can't start capturing: No space left on device

Extra details

  • I was looking for a solution and I found that USB cameras declare too much USB bandwidth usage and that it can be solved this way:
  • sudo rmmod uvcvideo; sudo modprobe uvcvideo quirks=128
    but I get this error rmmod: ERROR: Module uvcvideo is builtin.

I know I’m impatient, but could someone give me some advice on what to do?
