Writing an ALSA Driver — The Linux Kernel documentation
https://www.kernel.org/doc/html/v4.17/sound/kernel-api/writing-an-alsa-driver.html
strcpy (card->driver, "My Chip"); strcpy (card->shortname, "My Own Chip 123"); sprintf (card->longname, "%s at 0x%lx irq %i", card->shortname, chip->ioport, chip->irq); The driver field holds the minimal ID string of the chip. This is used by alsa-lib’s configurator, so keep it …
Writing device drivers in Linux: A brief tutorial
http://freesoftwaremagazine.com/articles/drivers_linux/
The reason for this choice is that good documentation for writing device drivers, the Linux device drivers book (see bibliography), lagged the release of the kernel in some months. This new version is also coming out soon after the release of the new 2.6 kernel, but up to date documentation is now readily available in Linux Weekly News making ...
Writing USB Device Driver in Linux - Stack Overflow

libusb is useful and easy to get up and running. I would suggest that you start there, especially if you haven't written Linux drivers in a while. Use libusb to understand what the signalling protocol is for the Roland GR-55 and do some experiments. USB supports several types of logical connections over the same physical wire.

This document describes how to write an ALSA (Advanced Linux Sound Architecture) (http://www.alsa-project.org/) driver. The document focuses mainly on the PCI soundcard. In the case of other device types, the API might be different, too. However, at least the ALSA kernel API is consistent, and therefore it would be still a bit help for writing them.

Writing a pseudo-device driver on Linux pseudo-devices are files, usually located in /dev , they're like a device file, but instead of acting as a bridge between the operating system and hardware, it's a device driver without an actual device. they usually serve a practical purpose, such as producing random data, or acting as a virtual sinkhole for unwanted data. examples would be files like …
More Notes on HD-Audio Driver — The Linux ... - Linux …
https://www.kernel.org/doc/html/v4.17/sound/hd-audio/notes.html
The HD-audio component consists of two parts: the controller chip and the codec chips on the HD-audio bus. Linux provides a single driver for all controllers, snd-hda-intel. Although the driver name contains a word of a well-known hardware vendor, it’s not specific to it but for all controller chips by other companies.
Writing a Simple USB Driver | Linux Journal

Software. Since this column began, it has discussed how a Linux driver writer can create various types of kernel drivers, by explaining the different kernel driver interfaces including TTY, serial, I2C and the driver core. It is time to move on now and focus on writing real drivers for real hardware. We start by explaining how to determine what kind of kernel driver interface to …
