Prolific USB-to-Serial Comm Port 安装好后,有个黄色的小感叹号，是驱动安装的不对，可以对应驱动选择安装或者在设备管理器里面端口中更新驱动。

Prolific USB-to-Serial Com Port在win10上经常不能正常驱动。安装这个驱动后，在设备管理器中选择更新驱动->浏览计算机查找->从计算机的设备驱动程序列表类选择->选择2009或者2008的那个

(支持Windows8/8.1)(32位/64位)PL2303_Prolific_DriverInstaller_v1.5.0 Due to EOL (End-of-Life) policy, please note that PL-2303HX (Chip Rev A) and PL-2303X (Chip Rev A) will not have driver support for the coming Windows 8 operating system as it is not a supported OS mentioned in the chip datasheet. So it is advisable to switch to the new PL2303TA chip which will include support for Windows 8.
