    Interface IHidChannel

    This is a wrapper for a stream of incoming IHidReports from a device and a callback to output IHidReports to the device.

    Each instance of IHidChannel is associated with only one device, and additionally, only one of its physical/wireless connections to the system.

    interface IHidChannel {
        descriptor: IHidUsage[];
        input: Observable<IHidReport>;
        getFeatureReport(usagePage: number, usage: number): Observable<number>;
        output(
            usagePage: number,
            usage: number,
            value: number | number[],
        ): Promise<void>;
        setFeatureReport(
            usagePage: number,
            usage: number,
            value: number | number[],
        ): void;
    }
