NotImplementedError is_kernel_driver_active on some Linux systems

There seems to be a regression in PyUSB 1.0.0b2 on some Linux based operating systems, downgrading to b1 should solve this issue.

If you already have BlinkStick Python package installed, please run the following commands:

sudo pip uninstall -y pyusb
sudo pip install pyusb==1.0.0b1

If you don't have BlinkStick Python package already installed on the system, run the following commands:

sudo pip install pyusb==1.0.0b1
sudo pip install blinkstick

Test by running the following command:

sudo blinkstick --info

If you don't want to run BlinkStick command script with sudo, please follow these instructions:
