检查adb 配置

在手机上插入usb后，如果想确认host是否识别该usb设备,可输入lsusb,如下：

BJS\lisa.liu@lisaliuubtpc:~/code/4.1_3.4x$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 004: ID 1782:5d04 Spreadtrum Communications Inc

如遇到“error: insufficient permissions for device“ ,可按如下方法解决：

BJS\lisa.liu@lisaliuubtpc:~/code/4.1_3.4x/out/target/product/sp8830eb$ sudo adb root
error: insufficient permissions for device
BJS\lisa.liu@lisaliuubtpc:~/code/4.1_3.4x/out/target/product/sp8830eb$ sudo adb kill-server
