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

no /dev/video at all. If I connect a usb2 webcam, that works, /dev/video0 appears.
user has access to the camera as the pylon software from the producer can see it immediately, could change the parameters such as the device name or resolution. But I need it in pd :)

1) do you see /dev/video* when you plug it in 
2) does your user have access to that

just like any other camera?

Dear list,

I use special 227fps usb cameras.
lsusb shows the id and the bus.
Bus 006 Device 002: ID 2676:ba02 Basler AG ace
How can I find the path to it and use with pix_video?
Test software shows device input.
device0-7 can not find it as /dev/video* does not exist.
Best,

Popesz
