GNU/Linux & USB – Read from USB In Endpoint Type Bulk Transfer in a Linux Driver
#GNU #Linux #Tutorial #Driver #DriverDevelopment
Let’s take a closer look at USB. In this series of tutorials we will learn how to implement an USB device on a microcontroller and interact with it over our GNU/Linux OS from user- and kernelspace.
I will show you how to read from USB Bulk In Endpoints from a Linux Driver. Therefore I will implement a gpiochip-compatible driver for my Atmega32U4 USB device.
