Ubuntu下adb默认无法识别,得到error: insufficient permissions for device,使用adb devices得到no permissions.解决办法有两种:
1.使用root账户(su到root账户)
su
cd Android-tools-dir
./adb kill-server
./adb start-server
./adb devices
2.修改udev的权限,猛击这里,添加/etc/udev/rules.d/50-android.rules
SUBSYSTEM==”usb”, SYSFS(idVendor)==”18d1“, MODE=”0666″
然后修改执行权限
chmod a+rx /etc/udev/rules.d/50-android.rules
重启udev
sudo restart udev
经测试,第一种方法成功,第二种方法失败.
On Ubuntu Linux
1.Plug-in your device then exec command ‘lsusb’ then you will see the list of current usb devices
Bus 003 Device 023: ID 18d1:d00d
We will see a device is appeared when it plug-in and disappeared when it plug-out. That device is we wanted and take my environment as an example it is located at line 1, “Bus 003 Device 023: ID 18d1:d00d”, without device provider.
2.Login as root and create this file: /etc/udev/rules.d/50-Android.rules
For Gusty/Hardy, edit the file to read:
SUBSYSTEM==”usb”, SYSFS(idVendor)==”18d1“, MODE=”0666″
For Dapper, edit the file to read:
SUBSYSTEM==”usb_device”, SYSFS(idVendor)==”18d1“, MODE=”0666″
P.S. the “18d1” is hard coded in android/kernel/drivers/usb/gadget/android_adb.c
#define DRIVER_VENDOR_ID
3.Nwx execute:
chmod a+rx /etc/udev/rules.d/50-android.rules
4.Restart udev to make the rule active.
sudo /etc/init.d/udev restart
