Hello there! It's been over a month since I last inquired about this, but I have an update and need some more guidance.
I installed Windows 7 on another computer I had and captured packets from when I pressed the 'Scan' button in the CanoScan tool. Now that I've got the packets captured in a .pcapng file (https://drive.google.com/file/d/1E0zErjd0PB3Ggmeop6iI43Gi0SCZ8K9m/view?usp=sharing), how do I analyze the packets and figure out the USB chip model? Thanks, -[K] IMSOASIAN (This is a continuation of a previous thread.
