PL2303 Windows8.1驱动
常用的USB转串口下载芯片驱动可以参照我这篇文章USB转串口 FT232/PL2303/CH340 驱动以及使用体会 ，今天有找出了那根串口线打算使用，由于系统已经换为Windows8.1 X64所以又去官网找驱动去了，一看悲剧了。官方信息如下：

上面已经包含最新1.9版本的驱动，支持xp-8.1的32和64位系统，但是PL-2303HXA和PL-2303X已经不支持了，拆了我的串口线一看果然是HXA的，这下悲剧了，还是装下试试看看，驱动能够安装，线也能够识别，但是无法启动。
下图是HXD的芯片，注意第一行后面的HX和第二行后面的D，现在淘宝也已经能够买到PL-2303TA的芯片了，和之前的2303是完全兼容的，所以如果使用windows8的朋友还是稍微注意下。
我在虚拟机的XP中用驱动中给的工具检查了下，果然是HXA。算了，还是换FT232的吧。
