Android Debug Bridge (adb) device - no permissions [duplicate]
I have a problem connecting HTC Wildfire A3333 in debugging mode with my Fedora Linux 17. Adb says:
./adb devices
List of devices attached
???????????? no permissions
my udev rules (first rule for Samsung which works just fine and second for HTC which is not):
SUBSYSTEM=="usb",SYSFS{idVendor}=="04e8",SYMLINK+="android_adb",MODE="0666",GROUP="plugdev"
SUBSYSTEM=="usb",SYSFS{idVendor}=="0bb4",SYMLINK+="android_adb",MODE="0666",GROUP="plugdev"
For Samsung devices everything's okay:
./adb devices
List of devices attached
00198a9422618e device
I have been trying all of the answers given in a simmilar thread wthout any luck: Using HTC wildfire for android development
Solution 1:
I just had this problem myself under Debian Wheezy. I restarted the adb daemon with sudo:
sudo ./adb kill-server
sudo ./adb start-server
sudo ./adb devices
Everything is working :)
Solution 2:
The cause of that problem has to do with system permissions (thanks @ IsaacCisneros for this suggestion). Somehow HTC Wildfire (and maybe the others) need something more from the system than Samsung devices. Simple solution is to run Eclipse as a root, but this is not very comfortable with non-sudo Linux systems like Fedora.
I've found another way of achieving the same goal, which seems to be more user friendly and is lesser security hole then running entire IDE with super user privileges. Mind this is still only a workaround of the problem. System root usage should be minimalized only to administrative tasks, and “adb” was designed to work with normal user account without SUID. Despite of the fact that the proper setting of SUID is quite secure, every single permission increase is a potential system security hole.
1.Setting ownership of the adb binary (owner – root, owner group - user_group):
chown root:user_group adb
2.Setting permissions with SUID:
chmod 4550 adb
This should result something similar to this (ls -llh):
-r-sr-x---. 1 root user_name 1.2M Jan 8 11:42 adb
After that you will be able to run adb as a root, event though you'll be using your normal user account. You can run Eclipse as a normal user and your HTC should be discovered properly.

I have a similar problem:

???????????? no permissions
Investigation
If I run lsusb
, I can see which devices I have connected, and where:
$ lsusb
...
Bus 002 Device 050: ID 04e8:6860 Samsung Electronics Co., Ltd GT-I9100 Phone ...
Bus 002 Device 049: ID 18d1:4e42 Google Inc.
This is showing my Samsung Galaxy S3 and my Nexus 7 (2012) connected.
Checking the permissions on those:
$ ls -l /dev/bus/usb/002/{049,050}
crw-rw-r-- 1 root root 189, 176 Oct 10 10:09 /dev/bus/usb/002/049
crw-rw-r--+ 1 root plugdev 189, 177 Oct 10 10:12 /dev/bus/usb/002/050
Wait. What? Where did that "plugdev" group come from?
$ cd /lib/udev/rules.d/
$ grep -R "6860.*plugdev" .
./40-libgphoto2-2.rules:ATTRS{idVendor}=="0bb4", ATTRS{idProduct}=="6860", \
ENV{ID_GPHOTO2}="1", ENV{GPHOTO2_DRIVER}="proprietary", \
ENV{ID_MEDIA_PLAYER}="1", MODE="0664", GROUP="plugdev"
./40-libgphoto2-2.rules:ATTRS{idVendor}=="04e8", ATTRS{idProduct}=="6860", \
ENV{ID_GPHOTO2}="1", ENV{GPHOTO2_DRIVER}="proprietary", \
ENV{ID_MEDIA_PLAYER}="1", MODE="0664", GROUP="plugdev"
(I've wrapped those lines)
Note the GROUP="plugdev"
lines. Also note that this doesn't work for the other device ID:
$ grep -Ri "4e42.*plugdev" .
(nothing is returned)
Fixing it
OK. So what's the fix?
Add a rule
Create a file /etc/udev/rules.d/99-adb.rules
containing the following line:
ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e42", ENV{ID_GPHOTO2}="1",
ENV{GPHOTO2_DRIVER}="proprietary", ENV{ID_MEDIA_PLAYER}="1",
MODE="0664", GROUP="plugdev"
This should be a single line, I've wrapped it here for readability
Restart udev
$ sudo udevadm control --reload-rules
$ sudo service udev restart
That's it
Unplug/replug your device.
Try it
$ adb devices
