(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.

PL2303USB转串口驱动，win7,xp,64/32全支持

PL2303 WIN10驱动。先安装USB-to-Serial Comm Port.exe，如果串口驱动依旧带有感叹号，请继续安装YH-340文件夹下的驱动，一般都可以解决。亲测有效。

win10 64位系统 PL2303驱动。亲测可用，安装前先把老的2303驱动卸载，再安装就可以了

本人电脑系统win7，需要使用USB-to-Serial Controller USB转串口驱动，安装了N个版本都有问题，一直提示“INF中的服务安装段落无效”。有类似问题的网友可参考一下我的解决方法。 解决办法： 压缩包中有1个驱动软件，1个inf文件，2个sys文件。 1、将mdmcpq.inf复制到c:\windows\inf 2、将usbser.sys和serenum.sys复制到c:\windows\system32\drivers 3、运行驱动软件PL2303_Prolific_DriverInstaller_10311,exe，进行安装。 说明： 1、上述inf文件和sys文件都是必不可少的，但是不同电脑所缺少的文件不同（我的电脑是缺少serenum.sys文件），缺少什么就复制相应文件到指定文件夹。 2、以上方法确实解决了我自己电脑上串口驱动不能正常使用的问题，但对于不同的电脑不能保证一定可行。
