Locate USB and serial devices

PolySync requires the mount point (commonly an absolute path) to the USB sensor or hardware device stored within the PolySync SDF. For Linux based systems USB devices enumerate within the /dev/ directory. Note that there can be a large number of other devices in this directory. With 1+ USB devices it is best to use discovery applications for identifying the mount point of each device.



The simplest method of determining the directory path of a mounted USB camera is to use the linux application v4lt.

$ sudo apt-get install v4lt-util
$ v4l2-ctl --list-devices
UVC Camera (046d:0821) (usb-0000:00:14.0-2):

Integrated Camera (usb-0000:00:14.0-8):


If you're unable to connect to a USB device, ensure that you have permissions to access the devices enumerated in the /dev/ directory:

$ sudo adduser [username-goes-here] dialout
