I just bought a second hand Samsung LE32B555A5W. It's very nice, but I wanted to see if I could enable Movie playing throught the USB port. After reading the Samygo wiki and googling a bit, I decided to try my luck and change my B550 model to B650. I know this is not recommended in the Wiki but it worked for me. I just wanted to share my success in case anyone searches for the same thing in the future.
My model details from the back label:
Model Code: LE32B555A5WXXE
Type No: LE32B555
From the Service Menu:
