I am working with an embedded Linux device (Raspberry Pi, Debian) with two identical USB cameras connected. The two cameras are attached on different physical location: one on front of our machine, one on top of it. So it is important to distinguish them.
However, what I can see in system is only
/dev/video1. Suppose I always connect the two cameras on fixed USB ports, how can I know which device file corresponds to which USB device?
I have tried lsusb, but it don't give information about the device files.
