openlogi_device/
write.rs

1//! HID++ reads and writes per feature — DPI, SmartShift, wheel modes,
2//! lighting, backlight, and diagnostics.
3//!
4//! Each entry point takes a [`DeviceRoute`] and resolves it to an open channel
5//! through `open_route_channel`, so the same call works whether the device is
6//! behind a Bolt receiver or attached directly (USB cable / Bluetooth). Each
7//! route-addressed call re-enumerates and re-opens, while the corresponding
8//! `_on` entry points reuse a [`crate::SharedChannel`] already owned by
9//! inventory or a standalone capture session.
