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 ...

[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 ...

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, ...

Microsoft's proprietary protocol, Remote Network Driver Interface Specification (RNDIS), started with a good idea. It would enable hardware vendors to add networking support to USB devices without ...

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 ...
