										<content:encoded><![CDATA[<p>這個應該是只有在 Windows 下才會有這個問題.<br />
抓舊版 Driver 就可以了. </p>
<p>20120104 Update: 移除舊版 Driver 的 Link, 留下名字, 大家自己再去 Google 挖.<br />
PL2303_Prolific_USB_To_Serial_Driver%2864BitWin7%29.zip</p>
<p>賣這麼好限制還這麼多, 真鳥. </p>
<p>P.S Linux 下不會有這個問題. </p>
<p>&#8212;- 20120104 &#8212;-<br />
如留言所示<br />
如果是這樣的話, 下次買 USB2Serial 還是要先測試一下. 試用不對再退貨?<br />
有沒有分辨正版 PL2303 的方法?</p>
<p>我是常買 USB2Serial ,  如果照留言講的是山寨版的話,<br />
那我中獎的機率還真高. 大概 30~50%.<br />
之前因為都是用 Linux, 所以都沒有發現.</p>
<p>而且以前 Profilic 也並未提到這件事情 , 請見<a href="http://web.archive.org/web/20110718063957/http://www.prolific.com.tw/eng/downloads.asp?ID=31" target="_blank" rel="noopener">以前的頁面</a><br />
所以 Profilic 最近才告訴大家山寨版 IC 這件事情. </p>
<p>&#8212;- 20120206 &#8212;-<br />
有特別去找 Profilic PL-2303*2 的 Device, 我是找到這個<br />
<a href="http://www.pcstore.com.tw/p6ecl1/M00304383.htm" target="_blank" rel="noopener">P6線上便利購 Prolific 讓 2 * RS232週邊變成USB隨插即用 (9 Pin)，支援最新Windows 7，ROHS無鉛製程，外銷機種，行動環保～</a> $760. 小貴, 不過比 shopping.pchome 上的 A-GOOD 的好. A-GOOD 是使用印度 <a href="http://www.moschip.com/" target="_blank" rel="noopener">Moschip</a> 的 Solution, 一買來就不能用, 我就退貨了. </p>
<p>以下是測試結果<br />

        |__ Port 3: Dev 7, If 0, Class=vend., Driver=pl2303, 12M</p>
<p>Linux 可以直接抓到, Windows XP 也 OK, Windows 7 我不想測了. </p>
<p>這一家也有賣 PL-2303*1 的版本<br />
<a href="http://www.pcstore.com.tw/p6ecl1/M00289747.htm" target="_blank" rel="noopener">P6線上便利購 &#8211; Prolific 讓RS232週邊變成USB隨插即用 (9 Pin)35CM，支援最新Windows Vista，ROHS無鉛製程，外銷機種，行動環保～</a> # $260 我覺得很便宜. </p>
<p>P.S 我還是不知道我買的這二顆 Chip 到底他媽的是不是真的 Profilic 的 Chip.<br />
P.S2 有長輩在 FreeBSD 下試過了, 這二個也可以正確抓到. </p>
