NUC前置C口，是个多功能口，除了连接usb设备，还支持“一线通”的功能，这得益于龙芯3B6000M处理器提供了USB3.1的满功能支持。

所谓“一线通”，实际上利用的是USB3.1 Type-C 传输视频，核心原理是 ‌USB 3.1 的 DisplayPort Alt 模式‌，它通过复用接口的差分信号线来实现视频、音频和数据的同步传输。

更详细的说，利用4对 TX/RX 差分线中的 2 对传输 DP 信号，剩余 2 对用于 USB3.1 数据传输，实现同时传输视频、音频以及usb接口的触摸功能。

中科云 3B6000M NUC 对该功能，进行了全面支持！

通过实际的测试，它的实现大致包含以下细节：

1、3B6000M有两个DC通道，适配HDMI、DP和EDP三种连接器，一线通连接的是HDMI这个通道。

2、当使用NUC的DP连接显示器，TypeC口连接触摸屏时，系统开启两个DC通道，提供屏幕克隆和扩展两种模式

3、当使用NUC的HDMI连接显示器，TypeC口连接触摸屏时，实际上使用的是一个DC通道，不推荐这么用。

4、触摸屏在2、3两种连接模式下，都可以使用。

推荐使用双DC通道模式，NUC预装的Loongnix20.7提供了驱动支持，诚鸿的开鸿社区OS系统，实测还未提供相关驱动支持
