Week Ten

This is the tenth week of being an intern at Aeste Works. Continuing from last week,  I found a way to separate normal USB packets and networking packets. This can be done by checking the twelfth and thirteenth byte of the payload found in the readBuffer. Protocols such as IPv4, Read more…
