Thanks. Your right. The only thing is that currently that line is a blank
string which means until now that system wasn't depending on that in order to
run. It's been loading the module from elsewhere. I'm going to change that
line for the network card. The USB mouse, however, looks like a more
complicated problem. I found on the web the following howto instruction:
~~~~
USB Human Interface Device (HID) Configuration
General HID Configuration
There are two options for using a USB mouse or a USB keyboard - the standalone Boot Protocol (HIDBP) way and the full featured HID driver way. The Boot Protocol way is generally inferior, and this document describes the full featured way. The Boot Protocol way may be appropriate for embedded systems and other systems with resource constraints and no real need for the full keyboard and mouse capabilities.
It is important to remember that the HID driver handles those devices (or actually those interfaces on each device) that claim to comply with the Human Interface Device (HID) specification. However the HID specification doesn't say anything about what the HID driver should do with information received from a HID device, or where the information that is sent to a device comes from, since this is obviously dependent on what the device is supposed to be doing, and what the operating system is. Linux (at the operating system kernel level) supports four interfaces to a HID device - keyboard, mouse, joystick and a generic interface, known as the event interface. These are implemented by the Input device level.
HID Mouse Configuration
In the kernel configuration stage, you need to turn on USB Human Interface Device (HID) support in the USB support and Mouse Support in the Input core support. You don't need to worry about the screen resolution entries for a normal mouse - these are for mouse-like devices such as a graphics tablet. Do not turn on USB HIDBP Mouse support. Perform the normal kernel rebuild and installation steps. If you are installing as modules, you need to load the input.o, hid.o and mousedev.o modules.
~~~~
there is no input.o or even input.ko in the mouse or usb source tree let alone
module library tree.
