While working with the library, we found that on a Linux system (Ubuntu, Rasperry Pi, etc.), the USB connection failed with an error such as:

File "hid.pyx", line 72, in hid.device.open_path
OSError: open failed

Firstly, be sure that you have installed all of the required dependencies for using godirect over USB. The proper command is:
pip install godirect[USB]

Secondly, on Linux systems, you will probably need to provide a udev rule to grant the proper permissions to the Go Direct devices. You can create such a rule in the proper directory with this command:
sudo su -c 'cat <<EOT >/etc/udev/rules.d/vstlibusb.rules SUBSYSTEM=="usb", ATTRS{idVendor}=="08f7", MODE="0666" SUBSYSTEM=="usb_device", ATTRS{idVendor}=="08f7", MODE="0666" EOT'
