With the use of Linux becoming increasingly common, including among the readers of Elektor Electronics, there is growing interest in Linux drivers for Elektor Electronics interface projects. One of the most successful projects in recent years was the USB interface presented in the September 2000 issue, for which a driver for Windows 98 was developed, but not for Linux. It’s time to set that right!Linux supports USB in kernel versions 2.4.0 and above. For kernel versions 2.2.16 and above, there is also limited USB support.
