資源簡(jiǎn)介
Usb設(shè)備插拔檢測(cè), 方法:利用檢測(cè)USB設(shè)備的PID, VID的方法進(jìn)行設(shè)備識(shí)別。
1.原型在codeproject, 原來(lái)版本是vs2005, 我改成了vs6.
2. 改成vs6后,在設(shè)備串比對(duì)的地方改了下。
整理時(shí)間: 2010/06/06 20:18
用途:做gina程序時(shí),有的Key驅(qū)動(dòng)不支持多進(jìn)程訪問(wèn)。我們只在必要的地方使用Key驅(qū)動(dòng)(讀寫(xiě)Key),在檢測(cè)key狀況時(shí),不再用讀Key的方法,來(lái)判斷Key設(shè)備是否在線。減小了沖突的可能。
當(dāng)然,如果Key驅(qū)動(dòng)做的好,就不用這種檢測(cè)方法。比如HaiTai的Key.
