The code consists of usbio.c and usbio.h and they are both located in "/usr/src/linux/drivers/usb". I added a line to Config.in, which auto-magically adds the necessary stuff to build and install the module. > > Do you want this driver included in the main kernel tree? > I don't know.

That's what generates the > module.usbmap file that the hotplug system uses to match up devices to > modules. depmod is run auto-magically by "make modules_install". As I said before, grep'ing the modules.usbmap file gives this result: usbio 0x0003 0x0fc5 0x1222 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00 0x00 0x00000000 which should tell "usb.agent" to use only the vendor ID and product ID (mask = 0x0003) to select a device driver. However, as I said before, the function "usb_map_modules()" in "usb.agent" is not being called. David Cullen May God bless you, and keep you, and may you one day experience eternal life, and all the joys that accompany it, in this life and the life to come, for eternal life is to know God, and the one whom He has sent, Jesus Christ, the Word manifest in the flesh. ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
