常用的USB轉串列埠下載晶片驅動可以參照我這篇文章USB轉串列埠 FT232/PL2303/CH340 驅動以及使用體會 ，今天有找出了那根串列埠線打算使用，由於系統已經換為Windows8.1 X64所以又去官網找驅動去了，一看悲劇了。官方資訊如下：

上面已經包含最新1.9版本的驅動，支援xp-8.1的32和64位系統，但是PL-2303HXA和PL-2303X已經不支援了，拆了我的串列埠線一看果然是HXA的，這下悲劇了，還是裝下試試看看，驅動能夠安裝，線也能夠識別，但是無法啟動。
下圖是HXD的晶片，注意第一行後面的HX和第二行後面的D，現在淘寶也已經能夠買到PL-2303TA的晶片了，和之前的2303是完全相容的，所以如果使用windows8的朋友還是稍微注意下。
我在虛擬機器的XP中用驅動中給的工具檢查了下，果然是HXA。算了，還是換FT232的吧。
