It is actually interesting to create something like a USB key with a single button in which the string will be sewn.
When you press the button, the line is spat out in the form of "line + pressing Enter" (as Chinese EM Marine card readers do).

The keyword is BadUSB, they do this based on a flash drive. If you really want to get confused - study microcontrollers, the principles of operation of USB, C for writing firmware. Then there will be more specific questions.

If you make your own USB device: study the specs, study the HID device spec. The toaster has tips on using the AVR lib to implement a USB stack and HID devices as an example. Look.

Buy some KIT with USB, such as stm discovery or similar (thousands of them). the examples will be all you need. and HID, and MSD, and CDC, and the devil is bald.
