Device Driver
============
======================
This folder contains a minimal **out-of-tree** Linux kernel module that acts as a USB **boot-protocol mouse** driver.
A collection of USB device drivers for Linux kernel, demonstrating how to interact with various USB HID devices.
It supports:
- Left and right buttons
- Scroll wheel
- Relative cursor motion (X/Y)
## Current Drivers
Important notes
---------------
### Mouse Driver (`mouse/`)
A USB HID mouse driver that supports 16-bit coordinate tracking for high-DPI gaming mice. Tested with Cooler Master MM710.
- This is an **educational** example. Real USB mice are normally handled by the kernel HID stack (e.g. `usbhid` / `hid-generic`).
- This driver binds to HID **Boot Mouse** interfaces (class=HID, subclass=BOOT, protocol=MOUSE). Many mice work, but not all.
- To use it on a running system you typically must **unbind** the existing driver from that USB interface first.
Files
-----
- `usb_bootmouse.c` kernel module (USB driver + input device)
- `Makefile` builds against your running kernel headers
Build
-----
Install kernel headers/build deps (examples):
- Debian/Ubuntu: `sudo apt-get install build-essential linux-headers-$(uname -r)`
- Fedora: `sudo dnf install @development-tools kernel-devel-$(uname -r)`
Then build:
**Features:**
- Left, right, middle, side, and extra button support
- 16-bit X/Y movement (high-speed tracking)
- Scroll wheel support
- Binds to HID Boot Protocol Mouse interfaces
**Building:**
```bash
cd Device-Driver
cd mouse/
make
```
Load
----
## USB Driver Manager
The `usb_driver_manager.py` tool simplifies the process of binding USB devices to custom drivers.
**Usage:**
```bash
sudo insmod usb_bootmouse.ko
dmesg | tail -n 50
# Search for .ko files in current directory
sudo python3 usb_driver_manager.py
# Search in specific directories
sudo python3 usb_driver_manager.py ./mouse ./keyboard
# The tool will:
# 1. List available USB HID devices
# 2. Show available kernel modules (.ko files)
# 3. Unbind the device from its current driver
# 4. Unload existing module (if already loaded)
# 5. Load the new module
# 6. Bind the device to the new driver
```
If you want to restrict binding to a specific device:
## Future Drivers
```bash
sudo insmod usb_bootmouse.ko match_vendor=0x046d match_product=0xc077
```
- **Keyboard**: USB HID keyboard driver
- **Racing Wheel**: USB racing wheel driver with force feedback
(Replace IDs with your mouse vendor/product from `lsusb`.)
## Requirements
Bind it to your mouse (unbind/bind)
---------------------------------
1) Find the USB interface path.
You can use `dmesg` when plugging the mouse in, or inspect:
```bash
ls -l /sys/bus/usb/devices/
```
Typical interface names look like `1-2:1.0` (bus-port:config.interface).
2) Unbind the existing HID driver (commonly `usbhid`) from that interface:
```bash
DEVIF="1-2:1.0" # <- change this
echo -n "$DEVIF" | sudo tee /sys/bus/usb/drivers/usbhid/unbind
```
3) Bind this module to the interface:
```bash
echo -n "$DEVIF" | sudo tee /sys/bus/usb/drivers/usb_bootmouse/bind
```
At this point, the driver should create an input device (via `evdev`).
Test
----
List input devices and find the new one:
```bash
cat /proc/bus/input/devices
```
Or use `evtest`:
```bash
sudo apt-get install evtest # or your distro equivalent
sudo evtest
```
You should see events:
- `BTN_LEFT`, `BTN_RIGHT`
- `REL_X`, `REL_Y`
- `REL_WHEEL`
Unload
------
```bash
sudo rmmod usb_bootmouse
```
If you want the original HID driver back, bind it again:
```bash
echo -n "$DEVIF" | sudo tee /sys/bus/usb/drivers/usbhid/bind
```
- Linux kernel headers
- Python 3.6+
- Root/sudo access for driver loading and binding
