LMR SDR 1.1: Achieved CAT Control!

I was planning to use a refurbished desktop computer for my homebrew LMR SDR 1.1. But that computer became out of order and could not be recovered in spite of all my efforts. Then I purchased and external stereo sound card for my laptop and connected it using a USB hub as I was short of USB ports on my laptop with several peripherals already in use, like external monitor, key board, mouse and printer. I connected the LINE IN of the LMR SDR 1.1 board to the mic input of the external sound card and the Arduino Nano was connected to the laptop using a USB Mini-B to USB cable. Installed PowerSDR 2.8.0, downloaded form YE3CIF’s website and configured it as suggested in VU3ZOF’s website.
