ADB devices cannot find a workaround for the device

1. Find the vender ID of the device

Windows methods: Pending additions

Mac OS:

Command line input: System_profiler spusbdatatype

My Nexus 7 has the following output:

       7 :           0x4ee2 0X18D1 (  Google Inc.)                       2.28           Serial Number:08bb6ada          480 MB/          sec          manufacturer:asus  0x14100000                     

Remember vendor ID:0X18D1

2. Modify ~/.android/adb_usb.ini (if not, create the file)

Add two lines

# Android 3RD Party USB VENDOR ID LIST--don't edit.# use ' android update adb ' to generate.# 1 USB VENDOR ID PER line.10 X18d1

Here 1 means the first device, if there are multiple devices in order plus one; 0X18D1 is the vendor ID. be careful not to have extra empty lines

3. ADB kill-server; ADB devices
