🐧 LINUX SETUP INSTRUCTIONS

Copy the contents of our recommended udev rules file:
- Our 55-moddo-hid.rules file
Create the rule file in the correct destination:
You can use an editor of choice instead of nano, but you must create the file as root (with sudo).
```
sudo nano /etc/udev/rules.d/55-moddo-hid.rules
```
Add recommended rules:
Paste the copied text into the editor (use Right-Click or Ctrl+Shift+V to paste in terminal).
Save and Exit:
For nano editor:
- Press Ctrl+O, then Enter to save (Write Out).
- Press Ctrl+X to exit nano.
Reload udev rules:
Tell the system to recognize the new file.
```
sudo udevadm control --reload-rules
sudo udevadm trigger
```
Apply changes:
Unplug and re-plug the USB device to apply the new permissions.

ACCELERATION REFERENCE

CURVE TYPES

Off: Passthrough (m = 1). Sens and Rotation still apply.
Linear: m = min(1 + accel·max(0, v − offset), cap). Constant-slope ramp above offset, plateaus at cap.
Natural: m = 1 + (limit − 1)·(1 − e^{−decay·max(0, v −
offset)}). Smooth asymptotic approach to limit above offset; decay sets how fast.
Inverse: m = min(1 + (accel·max(0, v − offset))^exp, cap). The inverse curvature of Natural: where Natural rises sharply then saturates, Inverse starts slow above offset and accelerates into the cap; exp sets the shape (1 = linear, >1 = slow start with steeper late ramp).
Boost: m = (1/v)·∫₀^v [1 + (limit − 1)·σ((u − threshold)/band)] du, where σ(x) = 1/(1+e^−x) is the sigmoid and band ∝ smooth·(threshold+1). Sensitivity stays at 1 below threshold, then asymptotically approaches limit above it. smooth=0 = hard step, smooth=1 = wide sigmoid blend.
Exponential: m = (1/v)·∫₀^v clamp((1+exp)·u^exp, offset, cap) du. Gain is clamped between offset (floor) and cap (ceiling); sensitivity is the time-average of that gain, so slow flicks sit at offset, mid speeds follow the power curve, fast flicks saturate at cap. Defaults cap=0, offset=0 reduce to m = v^exp. This is the only curve that can output m < 1, slowing precise motions. Smaller exp = gentler curve.

ALWAYS APPLIED

Sens: Flat multiplier on cursor speed, applied after the curve.
Rotation: Same setting as Angle Tuning: rotates the input vector in degrees applied at the sensor. Changing it here updates the Angle Tuning slider too.
Damping: Exponential Moving Average on the curve multiplier. No effect when Curve = Off.

v = raw input speed in counts/ms = sqrt(dx² + dy²) / dt.

Reset Acceleration?

This turns acceleration off and restores all curve and global values to their defaults.

Power Off Mouse?

After pressing Power Off, the mouse will shut down in 3 seconds.

Please disconnect the mouse USB-C within 30 seconds of pressing Power Off; it shuts down 3 seconds later.

To wake it back up, connect the mouse via USB-C.
