嗨埃里克， 请尝试重新安装最新的USB 3.0驱动程序包。 进入设备管理器中卸载USB 3.0主机控制器驱动程序重新启动您的计算机安装最新的驱动程序包。 注：您从任何蓝天/萨格尔或从USB 3.0控制器制造商下载并安装驱动程序更新（：瑞萨对于如）是很重要的 如果你仍然有问题，坚持使用原来的2.0.34.0驱动程序。 祝你好运， 詹姆斯

Hi Eric, Were your USB 3.0 devices being recognized properly before the update? If so, then you can try any of these options: OPTION 1. You can try uninstalling and re-installing USB 3.0 version 2.1.36.0 (10-May-12)... OPTION 2. You can try contacting Sager or Clevo to ask for the most updated USB 3.0 driver version for Windows 7... OPTION 3. You can try rolling back your version 2.1.36.0 (10-May-12) driver update to version 2.0.34.0 (10-Feb-11)... OPTION 4. If you can\'t roll back the version 2.1.36.0 (10-May-12) driver update to version 2.0.34.0 (10-Feb-11), then you can try uninstalling it and re-installing version 2.0.34.0 (10-Feb-11). If you don\'t have the installer for this driver version, try these Sager NP7280 (Clevo x7200) USB 3.0 driver installers: *** Clevo USB 3.0 Driver Update Version 2.0.34.0, Apr 29 2011 for Windows 7 -- ftp://usftp.clevo.com.tw/X7200/OTHERS/USB30.zip *** Sager USB 3.0 Driver Update Version 2.0.34.0, May 12 2011 for Windows 7 and Windows Vista 32-bit and 64-bit -- http://www2.sagernotebook.com/Sagernotebook/misc/06USB_NP7280.exe Let us know if any of the options above works.
