Issue with connecting to AGUC8 device

[guranshmann]

Hi there,
I am trying to use this script to connect and control an AG-UC8 motor however I'm facing issues while connecting to the port.
In the documentation, I was able to install the package successfully but when I run this command, I keep getting errors:

For the port, I tried finding the port using dmesg grep, and for the socket I was using dev/ttyS0 but I keep getting this error:

When I try using ttyUSB0 instead of ttyS0, I get this error:

It seems like I might be using using the wrong port. When I list the devices connected using lsusb, it shows me only the bus and the device ID:

Any sort of help would be appreciated.
Thank you in advance!
