Linux和mac下都能够直接连接，可是windows下必须下驱动。
官网上的driver无论用。管用的是 https://drive.google.com/uc?id=0Bw8B2a85Qa1jSldjc3RIM3pkNWc
然后在device manager里，Update Driver Software -> Browse for the driver software on your computer -> Let me pick from a list from ....
-> 选择Android Device -> 选择Have Disk -> 选择下载文件夹中的inf文件。然后在Manufacturer能够看到ASUSTek COMPUTER INC. Model选择ASUS Android ADB Interface
然后在tablet里面在Developer option里勾选起Allow USB debug，而且在Storage的右上角取消全部的选项！！！
这样tablet就会提示是否连接电脑，就能在adb devices看到设备
