You don't say what kernel version you are using, but devfs is deprecated and there are patches around that remove it from the latest kernel tree. For 2.6.recent, what you want to use is called 'udev'. It comes with most current Linux distros. You can add rules to it for device naming if you need to do that. See http://www.reactivated.net/writing_udev_rules.html and http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev.html > The problem: I have an application I have developed that requires two > USB HID devices.
