I'm working on a custom device driver. I've created my source files in the /usr/src/sys/dev tree as well as created a corresponding directory in /usr/src/sys/modules with a Makefile, and updated the parent Makefile. I can indeed generate a kernel object and load it into the active kernel, but it doesn't appear to get called when my device (USB in this case) is attached. If I add my device to the kernel conf file and build a custom kernel, it works fine. I've used other device drivers as a template and have included all the declarations the appear to be necessary : USB_DECLARE_DRIVER(ulabjack); DRIVER_MODULE(ulabjack, uhub, ulabjack_driver, ulabjack_devclass, usbd_driver_load, 0); During my development it's a lot easier to load/unload/modify the driver without recompiling the kernel. So what step am I missing? Chris
