虚拟机挂载USB设备/USB serial 连接开发板

**虚拟机挂载USB设备/USB serial连接开发板**

在软件开发中，使用虚拟机（Virtual Machine）是一个非常常见的做法。然而，当我们需要与外部硬件进行交互时，例如连接开发板、读取数据或控制外设等，就会遇到一个问题：如何让虚拟机识别和访问这些外部设备。

在本文中，我们将讨论如何在虚拟机中挂载USB设备/USB serial连接开发板。我们将使用QEMU作为虚拟机的基础，并使用libusb来控制USB设备。

**环境准备**

首先，我们需要准备好一个支持USB和USB serial功能的虚拟机环境。这里，我们选择使用QEMU作为虚拟机的基础。
