Hello Community, can you help me with this issue in TinyRadTool.

Question

I cloned the git repository for TinRad tool from this link . After successfully installing all the dependencies and the tool they have provided. I went on to run the code. 
 But the code showed some unexpected errors which can be seen in the picture. 
 Can please anyone help me with the following issue?

Ubuntu Version: 20.04 
 ROS Distro: ROS Noetic

Hi Dsachdeva 
 It seems like the PyUSB library couldn't find the TinyRad. Did you connect TinyRad to the USB 3.1 port of the PC? TinyRad uses USB 2.0 protocol for data transfer but for power consumption needs, it must be supplied from a USB 3.1 port. 
 There is a known bug in the source code that it cannot run unless TinyRad is connected. 
 If you like to examine the code/algorithms, there is AppNotes for Python in the V1.1.2 release which is a stripped-down version of the GUI. 
 Thanks,
