在介绍设备端驱动前，我们先来看看 Linux USB子系统。这里的子系统是相对于整个Linux kernel 来说的，而非单一设备。从整体概括了USB主机端和设备端的通信框架。 Linux kernel 中早已集成了较为完善的USB协议栈，由于其规模庞大，包含多个类别的设备驱动，所以Linux ...

USB drivers included in the Linux kernel are rife with security flaws that in some cases can be exploited to run untrusted code and take over users' computers. The vast majority of these ...

In theory, writing a Linux device driver shouldn’t be that hard, but it is harder than it looks. However, using libusb, you can easily deal with USB devices from user space, which, for many purposes, ...

Running Linux from a USB drive is possible. You can boot just about any distribution you want from USB. There are some things you should consider before going this route. I've used Linux in just about ...

In Part I of this article, I briefly mentioned the generic USB driver in the context of getting a USB device to communicate through it easily, with no custom kernel programming. Unfortunately, I ...

In my last column [see LJ December 2002], we covered the serial layer in the 2.5 (hopefully soon to be 2.6) kernel tree. We mentioned in passing that a USB-to-serial driver layer in the kernel helps ...

Editor's Note: Embedded Linux has consistently ranked among the top operating systems used in embedded system design. With the rapid growth in interest in the Internet of Things (IoT), the ability of ...

[Johannes 4GNU_Linux] has been filming a video series on how to write Linux device drivers for a couple of years now, but luckily, you won’t need that long to watch them or to create your own driver.

In previous articles, we looked at how to configure the kernel as well as the key components of an embedded operating system (OS). This new article focuses on the hardware components of embedded Linux ...
