How to connect Android 7.1 to Ubuntu Linux with USB?

I’m trying to connect a Google Pixel phone, with android 7.1, to a Ubuntu 16.04 laptop with a USB cable using mtp-tools. But the mtp doesn’t see the phone file system and gives the error message «Get Storage information failed». Then trying the mtp tools .

Connect Android and Linux using USB

I have a Samsung Galaxy Tab 2 tablet, running Android 4.1.1 (aka Jelly Bean). I’d like to transfer some files from the tablet to my Linux server running Debian 7.2 (aka Wheezy). The Android tablet connects via Wi-Fi to the same LAN as the Linux server.

There are many ways to transfer files between the 2 devices. For example, you could install an Android app named AirDroid which lets you manage your Android device from a desktop web browser, including file transfer. In this post, I’ll go another route, an arguably more direct and basic one. I’ll connect the 2 using a USB cable.

1. Connect the 2 devices using a USB cable.
2. With the Android device, navigate to the home page.
3. Swipe down from the top of the page. You will see a message «Connected as a media device. Touch for other USB options»
4. Tap on the message. The resulting screen specifies how you want the Android device to connect: as a Media device(MTP) or a Camera (PTP). While Linux has some support for MTP, I found it much easier to connect as PTP.
5. Tap on the Camera (PTP) checkbox.
6. Swipe down from home page again, and you will see that the tablet is mounted as a camera.
7. Reset the USB device under Linux. The simplest way is to unplug the USB cable from both ends, and plug it back in.
8. Make sure that the Android device is mounted on your Linux server. On my Linux GNOME 3 desktop, I clicked on the Computer icon, and the Android device was detected (GT-P3113). Click the device to mount it.
9. Run your favourite file manager application on Linux, and proceed to transfer files.

You can use the above method to transfer files if you happen to have (the right) USB cable around to connect the 2 devices. If cables is not your preference, you may want to look into the Android app Airdroid.

This means your phone is set to the «USB for charging the phone» instead of PTP. You can get at this in settings/bt and device connection/usb.
The usb may not show until it’s actually connected by the cable.

Incidentally the cable must be a «charging and data transfer» type of cable. The newer ones ARE, but if you have an older phone, you’re going to need to find a cable that support data transfer. assuming your phone can do this, of course.

If you’ve had it connected to a Windows computer before, it will transfer data. January 9, 2020 at 4:13 PM Skitnevsky said. I just done this from start to finish. Worked a charm. Thank you.

How to usb-connect android devices with adb under ubuntu [closed]

you probably run into the same problem like me. However, I found on the internet some more or less sub optimal solutions The basic idea is to start adb as root. The solutions I found were cumbersome. One proposal is to start adb per sudo. An other proposal was to set up a boot script in /etc/init.d My solution is to give adb the permission to start as root. To do so, switch to root

sudo bash chown root adb chmod ug+s-w adb 

sudo chown root adb sudo chmod ug+s-w adb 

Please do not do this! The authors of the adb program did not intend for its development machine side to be run as root, but rather to use a udev rule to allow access to listed device types only. Trusting a program more than its authors recommend is a bad idea! Also, voting to close as there’s not actually a question stated, while the topic has already been covered numerous times.

The Google recommended way to deal with ADB device permissions is to create an UDEV rule which would set appropriate permissions on device enumeration.

If you’re developing on Ubuntu Linux, you need to add a udev rules file that contains a USB configuration for each type of device you want to use for development. In the rules file, each device manufacturer is identified by a unique vendor ID, as specified by the ATTR property. For a list of vendor IDs, see USB Vendor IDs, below. To set up device detection on Ubuntu Linux: Log in as root and create this file: /etc/udev/rules.d/51-android.rules. Use this format to add each vendor to the file: SUBSYSTEM==»usb», ATTR==»0bb4″, MODE=»0666″, GROUP=»plugdev»

In this example, the vendor ID is for HTC. The MODE assignment specifies read/write permissions, and GROUP defines which Unix group owns the device node. Note: The rule syntax may vary slightly depending on your environment. Consult the udev documentation for your system as needed. For an overview of rule syntax, see this guide to writing udev rules. Now execute: chmod a+r /etc/udev/rules.d/51-android.rules When plugged in over USB, can verify that your device is connected by executing adb devices from your SDK platform-tools/ directory. If connected, you’ll see the device name listed as a «device.»

Connect Android To Arch Linux Via USB – Connect over MTP in Linux

In this article, we’ll talk about how we can connect Android to ArchLinux via USB. When using Arch as a daily driver, you often might need transfer data between your phone and PC. However, like most other things, this is not enabled by default on Arch. In this module, we will learn how we do so using some very easy steps.

How to Connect Android To Arch Linux with a USB?

After a vanilla Arch installation you might notice that your File Manager doesn’t list your device even when it is connected to your PC via an USB.

This is because we don’t have MTP support enabled. MTP ( Media Transfer Protocol ) is a protocol that lets you access Android File System. This protocol is not enabled by default on Arch.

Enable MTP Support with mtpfs

First enable MTP support by installing :

For devices running Android 4+, this should do the trick. However, on later versions, we would need another package called jmtpfs from AUR repository. You can fetch it by:

At this point, we have MTP enabled. However, it would still not be visible in your File Manager as it is not auto-mounted as we desire. To auto mount it, we need to install a package with :

Enable PTP Support

PTP stands for “Picture Transfer Protocol” and infact is the protocol on which MTP is based. When you communicate with your Android phone via PTP, it appears as a digital camera to your PC.

To enable PTP, we need to install a package with :

$ sudo pacman -Sy gvfs-gphoto2

Finally, for the changes to take effect, we need to reboot the system which can be done with :

Accessing Device Files

Once the system restarts, connect your Android Device via an USB to your PC and when the Device gives you a pop up, chose the desired option.

Now, your File Manager should list your device and you can access the Device files easily !

Conclusion

Note that this method works only for Android Phones only and won’t work with iPhones as it uses a different set of methods to connect to PCs. Hope you now know exactly how to connect Android to Arch Linux via USB over MTP/PTP for your file transfer. Stay tuned for further articles!
