Folks,

Any help will be appreciated. I'm using a Microsoft LifeCam HD-3000 on my 3d printer (Creality Ender-3/V3 KE). It is a proper V4L2 device, but whatever I try, I only get a protocol error. I've been searching around, but can't seem to find info on that specific error message. See info below.
