[Tutorial] ADB on (X)ubuntu

You have a problem with ADB on your (X)Ubuntu? "ADB not found", "No Device connected" even you set USB debugging?
I got the same problems when I started to play around with Xubuntu.
So I wrote a tutorial how to get ADB running properly under my Xubuntu installation.
Maybe it helps some people.
ADB on (X)ubuntu

I've enabled "USB debugging" under Settings-->Applications-->Development.
And when I directly connect the USB cable to my Ubuntu machine "lsusb" shows nothing.
I also get no USB icon in notification area on my tablet.
What am I doing wrong?!
Please help!

Worked beautifully
Thanks for the adb tutorial. I am running xubuntu on an old Dell Inspiron 1318.
Some tips I found help:
1. I used leafpad to create the 51_android... File
2. I added both "0x1949" and "1949" vendor IDs
3. As soon as I did this adb recognized my device in TWRP with a regular usb cable.
4. I had to execute each adb command with the "./" prefix, state such as "./adb devices"
5. I side loaded cm10 zip and rebooted in TWRP
6. Then I side loaded gapps zip and rebooted
Voila!
Thanks Hascode, PowerPoint 45, and others!

[Q] ADB not showing device

Hi, my problem is this: my phone is recognized as an ADB device but I cannot see it under adb devices.
Currently running PA RC2 3.99
Fastboot and Recovery do recognize it but ADB does not.
I have the drivers from here installed them as described in the instructions with uninstalling + deleting the old ones and rebooting.
I also have the most updated version of ADB from Android SDK.
One weird thing is that if i uninstall + delete the current drivers and try to install the ones i got from the SDK and not from the thread I mentioned then it does not install them. So maybe that is where my problem...
Any advice??
Thanks in advance.

Did you enable usb debugging?

Also check that you have an option selected under Settings>Storage>USB Computer connection, not having either MTP or PTP selected there will also bork adb.

If you still can't get it to work, try Koush's universal drivers: Link

still not working...
1. Yes, usb debugging is on.......
2. Already tried toggling MTP/PTP/None - When on MTP driver installs successfully but I cannot see the device under adb devices. on the other two options (PTP/None) I am unable to install the driver (tried both the ones on XDA and the ones from MDK)
3. Tried Koush's universal driver - on PTP/None still not able to install drivers. On MTP didn't do much except for changing device name from Android ADB Device to Google Nexus ADB Interface
Thanks for all the quick replies,
Any other suggestions???

what does it say when you issue the "adb devices" command? Please write it out here so we can help you. Does it say "device offline"? If yes, then your device is not registered by digital fingerprint by Android SDK.

Ok, so I'm with my Nexus connected as an MTP device, with the driver from XDA installed (see attached image), USB Debugging enabled:
Code:
C:\>adb kill-server
C:\>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
C:\>adb devices
List of devices attached
C:\>

Any advice???
Anyone has any advice??
I really have not idea what to do. Tried everything...
Thanks

Works on a different computer
I've connected the phone to my borther's PC and installed the drivers from the SDK. It worked without any problem.
I really can't figure out why it's not working on my laptop.

[Solved]
OK...
So as I said before I tried connecting when PTP is checked and when neither PTP nor MTP are checked and on both couldn't install the drivers properly (neither from xda nor from sdk).
What worked for me:
1. Uncheck both PTP & MTP
2. Device Manager -> Nexus 4 -> Update Driver Software -> Browse my computer for driver software
3. Now instead of browsing to the location I went to "Let me pick from a list..."
4. It should show a list of devices/manufacturers. Clicked "Show All Devices"
5. On the bottom right click "Have a disk"
6. Point to the android_winusb.inf file from Android SDK
7. Choose Android ADB Interface from the list
8. Let driver install

Thanks to everyone that tried to help. :good:

ADB does not prompt to accept any USB debugging authorization after root

Hi,
I recently rooted my Samsung Galaxy Tab A thanks to the wonderful folks of this forum. However, now that it's rooted I can't seem to connect to it via adb. For example, I see the device listed when I run "adb devices", but it is listed as "unauthorized". I no longer received the prompt to allow USB debugging. More precisely, I can still access the developer options and see that "USB debugging" is enabled, I just don't receive the pop-up prompt to "Allow USB debugging?" that list my local computer's RSA fingerprint/etc after I plug in the usb... the device just remains unauthorized and never asks me to click ok to allow usb debugging.
As suggested elsewhere, I tried removing the adbkey and adbkey.pub in the .android directory on my local computer and the killing/starting the adb server to generate new keys on the local machine, but that also doesn't seem to help...
Additionally, I noted that there is also no longer a button under developer option to "Revoke USB authorizaiton" (maybe because there are now no longer any keys in /data/misc/adb/adb_keys ?)
Any idea how to get adb shell to work again? Or maybe it not possible after rooting?
Thanks!

I finally solved this problem.... I don't think it was particular to the Galaxy Tab A.
In order to get adb working again I had to put the device into recovery mode (power down, then power up while holding power, up-volume, home button). I then went to the terminal application of the Team Win Recovery. In terminal I issues "stop adbd" then "start adbd". At this point the device now shows up on the local host PC when I run "adb devices" (it shows up as "recovery" rather than unauthorized). I can adb root/shell to the device now. This is really all I need to do. I expect this will solve my problem in non-recovery mode as well. Or, at this point I can push my PC pub key to the device and it should be fine.

Nexus 7 2012 bricked, adb/fastboot connection ok but unauthorized. Can You help?

Hi.
I have a nexus 7 2012 edition which turns on with The Google written logo and under the screen with a padlock. After that it will be in bootloop with a black screen ( I can see the backlight turning on/off). This is also if pressing the power+volume down combination. Seems bootloader is corrupted. Anyway I installed everything on pc plus I'm using the WugFresh Nexus Root Toolkit and here are some examples which show what errors I'm encountering when trying to flash stock firmware .
Log:
Checking ADB/FASTBOOT Connectivity
adb devices
015d4a5ed8500c01 unauthorized
fastboot devices
There is also a notification popup which tells me:
"An ADB Interface device was found but it was listed as "unauthorized"
-Accept the RSA security prompt and check "Always allow from this computer"
At this point I don't know what to do, can you help me?

Same issue - following
I have the same issue now after trying to flash a kernel to fix the slow charging issue. Following this post for any update.

Hi, Sunil_511...
Bit speculative this, and I can't say for certain if the following solution would work, because I've never had this problem myself. It also requires that your Nexus 7 be in a fully bootable state.
Go to your Nexus 7 Developer Options in the devices settings and tap on 'Revoke USB debugging authorisations'. Tap on OK to confirm. See attached screenshot.
This, theoretically, should wipe the slate clean.
Reboot both your N7 and your PC/laptop and when you next reconnect your N7 to your PC/laptop, you'll be asked to authorise this new USB connection when you perform some action that requires it.
Well, that's the plan anyway.
Good luck?.
Rgrds,
Ged.

Nope, in my case my tab is not booting to recovery or system. The only option is adb and it is showing unauthorized. My last option what i think off is to change the motherboard.

Google search is your friend. I found the following two methods which seems to have worked for some people.
1. If you are using OS X*:
Reboot your phone into recovery mode.
Connect it to your computer.
Open the terminal and type:
cd ~/.android
adb push adbkey.pub /data/misc/adb/adb_keys
All done! Just adb shell reboot and feel the power!
*For Windows 10, .android directory is located in your the base of your C:\User\user_name directory.
2. Go to where you have stored adb files, open that folder and press "CTRL+SHIFT+Right Click" and select and click on Open Command Prompt option
Now enter following command
adb start-server (Enter)
adb usb (Enter)
After that your device is no longer unauthorized and you should be able to use any command in your Android Mobile using PC/ Computer.
If these fixes don't work, SEARCH.

thanks buddy, i have tried pushing the adb keys but no luck. I will try tge second option. Will let you know after trying.

No difference still the same

Tried your suggestion.. Which i might have tried eventually from googling.. Doesn't make any difference.

Fixed
After doing all the researches, i had to buy a new motherboard and then replace it. Installed new rom and now using it. Spared about 1400INR for a 32 gig version.

Nothing unfortunately :/ the prompt never shows, no matter what i try.

Bump

Bump. Im in the same boat

Try
1) unplug v20
2) go into developer options then click Revoke USB debugging authorizations
3) plug v20 in, unlock v20 screen
4) type adb devices
5) authorize the popup you see on the phone
You should be good.
