魅蓝note 不出现 允许 usb 调试的 对话框

first ensure you have adb_usb.ini exist if not refer to :

http://www.crifan.com/adt_android_can_not_find_adb_usb_ini_file/

briefly you create one:

# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.
0x1949
0x18D1 

vendor id can be found at:

USBVID_2A45&PID_0C02&REV_????&MI_00
USBVID_2A45&PID_0C02&MI_00

then issue following command:

adb kill-server

adb start-server
