PTZ control for usb camera's

Hi there,
i am trying to get some control for my Lumens ptz camera’s in touchdesigner.
The camera’s i use are Lumens VC-B11U

I found that it would have to be with a python script of some kind, but i am stuck at it.
Is there an easy way to send commands to the usb interface?
i have the SDK with the command list, they look like this “0xDB” with values “1 2 3 … 4”

Hope someone can get me on the right track…
Thanks in advance!
Kind regards,
David
