cap.available_modes empty

[enlightment84]

I had successfully connected to the cam, but the available_mode is empty. I slightly modified the example.py.

from future import print_function
import uvc
import logging

logging.basicConfig(level=logging.INFO)

dev_list = uvc.device_list()

for index, cam in enumerate(dev_list) :
print("[" + str(index) + "]" + str(cam));

cap = uvc.Capture(dev_list[0]["uid"]);

print(cap)
print(cap.avaible_modes)
print(cap.frame_mode)
cap.get_frame_robust()

---

RESULT :

This indicates that either the drivers are not installed correctly (on Windows) or the user is not part of the plugdev group (on Ubuntu).

Thanks for your fast response @papr. I have actually double checked the installation of the camera driver. I am pretty sure that I follow correctly the guidance in https://github.com/papr/pyuvc/blob/master/WINDOWS_USER.md. I have checked also the installed driver in the device manager. Below picture shows my confirmation on the status of the installed driver and the steps. Hope you can help. Thx.
