[PD] high speed usb3 camera can not be found

[Csaba Láng]

I am a step closer to what find the devices. Looks like they appear in
/dev/bus/usb/busnumbers and when I click on the [device
/dev/bus/usb/006/002( for example, this is what pd prints out:

videoctl: device /dev/bus/usb/006/002
Cannot open '/dev/bus/usb/006/002': 25, Inappropriate ioctl for device

What does it mean exactly?
The device works on 227fps

Best,
Popesz
