./adv devices gives me the following result. How do I get rid of the “no permissions”
Thank you.

Hi kvrao,
open the terminal and login as root, see if this helps (it should work)
sudo apt-get install android-tools-adb android-tools-fastboot
try to install adb and fastboot

Ramesh,
Thank you, I installed latest adb and fastboot. However, my laptop with ubuntu recognize the dragonboard 410c device with the same result “no permissions”.
Is there another way around this.
Regards,
kvrao
have you tried rebooting the adb server with superuser priviledges?
$ adb kill-server
$ sudo adb start-server
$ adb shell
or maybe modify the device udev rules if you are using a linux host?
Result of the third step that you suggested:“insufficient permissions for device”.
Yes jro, I am trying to work the dragonboard 410c with ubuntu 14 on my laptop. This is my second attempt at Coursera’s IoT. I had quit at this point in the past when I tried with windows. I resumed attempting with ubuntu this time, and am still struggling as an amateur on this topic.
kvrao@kvrao-Satellite-C55D-B:~/Android/Sdk/platform-tools$ adb shell
- daemon not running. starting it now on port 5037 *
- daemon started successfully *
error: insufficient permissions for device
kvrao@kvrao-Satellite-C55D-B:~/Android/Sdk/platform-tools$
Are you sure you followed the steps as I wrote them? Is it possible that you have missed
$ sudo adb start-server
before executing adb shell
Beg your pardon: a correction on my part. The result is as below.->
kvrao@kvrao-Satellite-C55D-B:~/Android/Sdk/platform-tools$ sudo adb start-serverkvrao@kvrao-Satellite-C55D-B:~/Android/Sdk/platform-tools$ adb shell
shell@msm8916_64:/ $
Having done the above,I went back to the terminal to see if all was good. The unsuccessful result is below:
kvrao@kvrao-Satellite-C55D-B:~/Android/Sdk/platform-tools$ ./adb devices

you seem to have two adb servers installed
if you want to use the one provided by the SDK then
~/Android/Sdk/platform-tools$ ./adb kill-server
~/Android/Sdk/platform-tools$ sudo ./adb start-server
~/Android/Sdk/platform-tools$ ./adb shell
if you want to use the one in your path:
$ adb kill-server
$ sudo adb start-server
$ adb shell
kvrao@kvrao-Satellite-C55D-B:~/Android/Sdk/platform-tools$
kvrao@kvrao-Satellite-C55D-B:~/Android/Sdk/platform-tools$ ./adb kill-serverkvrao@kvrao-Satellite-C55D-B:~/Android/Sdk/platform-tools$ sudo ./adb start-server

- daemon started successfully *
kvrao@kvrao-Satellite-C55D-B:~/Android/Sdk/platform-tools$ ./adb shellshell@msm8916_64:/ $
Both give the result as above. My novice question would be: Does this solve my problem of “no permissions” where I originally started this thread?
Thank you jro
yes.
the way you have setup your device means that you need to make sure the server is started with superuser privileges.
Maybe it would be a good idea to remove the adb server that is on your path and use only the one on the SDK since it seems to confuse you more than help (so add the path to the SDK/tools to your bashrc)
Hello jro,
This permissions thing is hounding me again. This time I enabled the dragon board 410c to wireless communicate with my laptop host. Following your guidelines I checked it does connect and communicate.
I am perplexed, when you say “the way you have setup your device means that you need to make sure the server is started with superuser privileges.”
I followed the video instructions of coursera.org and am unable to access the device with a basic command of ./adb device. This time wireless way.
Pray correct me, so I can follow the simple path. Thank you kindly.
kvrao
After doing the following that is listed below. I cannot communicate with the dragonboard 410c after the usb connection is removed. The command adb devices does not work wireless. Please advise how I can get the wireless part working.
Thank you.
kvrao.

Dear jro,
When I try to fastboot the dragonboard 410c. I get the same “no permissions” message as you see in the snapshot below. Please show me a way to get rid of the “no permissions” message permanently.
Thank you,
