Ubuntu No devices permission

---

How do I fix this issue?
I am a linux n00bie

giovanni@giovanni-laptop:~$ adb devices
List of devices attached
???????????? no permissions

You need to create a file named

/etc/udev/rules.d/51-android.rules

containing the line:

SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"

you need to be root to create the file, use

sudo -s

to become root, then

gedit /etc/udev/rules.d/51-android.rules

will open the new file for editing.

You'll have to reboot when done.

Thank you for your help and please excuse my ignorance in linux.
I just installed ubuntu today

The above didn't seem to work after a reboot.
I did successfully create the file however.

Any ideas?

Thanks.

There is another Vendor id for NexusOne. "0bb4" is not for Nexus but G1:

Working record for Nexus is:

SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", MODE="0666"

As stated by DEEsx1 the following is correct:

SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", MODE="0666"

However, it has been a mystery as to why the following location/file does not work for everyone:

/etc/udev/rules.d/51-android.rules

I am running Ubuntu 9.10 on my laptop with nothing special, just a straight load. the 51-android.rules code did not work for me.

I searched around on a few linux/android forums and found that some people had luck with creating the following file:

/etc/udev/rules.d/90-android.rules

However, that did not work for me. I had to create the following file:

/etc/udev/rules.d/99-android.rules

Now, if you are still getting the error, you don't need to reboot, you just need to restart udev:

sudo /etc/init.d/udev restart

You may also need to restart the adb daemon:

adb kill-server
adb start-server
adb devices

Now, worse case that I have seen, make sure the phone is not plugged into the computer, reboot the system AND the phone then try again (I have only seen this once).

Hope these tips help!

You are correct, I didn't realize I had two udev files and I opened the wrong one.

thanks for your help! I'll try this out when I get home.

Yay! it worked. Thanks for your help.

Just out of curiosity how in the hell would I have otherwise known to create a file with a seemingly random name in a random folder?

and why 51-android.rules? why not 1-android or 5000000-android?

What's the logic there?

thanks again

Welcome to Linux!

Actually, the more you use it, you'll find that you'll pickup these bits along the way, just like this.

The files are processed in order of their name so 51-xxx is mid-way through, 99-xx is at the tail end of the processing order. Sometimes, the order is important.

Also, after posting the wrong info to you earlier, I deleted the entry I posted. But, it turns out, the Nexus one poses as both id numbers. While in Android its VendorId=18d1, but in the bootloader (waiting in fastboot usb), the VendorId=0bb4.

So, I put both lines in one file today and all is well again.

I.e:
SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"
SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", MODE="0666"

and I changed my filename to 99-android.rules

then ran:
sudo restart udev

and now I can access the phone as a non root user again, either from adb or fastboot-linux.

Thanks for this! You're a life saver. Actually a hair saver, I get to quit pulling mine out now!
