My android auto was working intermittently and then has stopped working entirely. This is only the bottom 2 ports (1 and 2). The top ones on 1 and 2 charge. Different phones and cables all fail to charge or work with android auto. The rear ports all work except the uconnect does not read the rear USB port now. I did factory reset, cleared cache, restart device, remove battery, but it won't work. From Hashken' USB Debugging Mode is one thing that you cannot skip to know if you are an Android user. The primary function of this mode is to facilitate a connection between an Android device and a computer with Android SDK (Software Development Kit). Download and install Android File Transfer on your computer. Open Android File Transfer. The next time that you connect your phone, it opens automatically. Unlock your phone. With a USB cable, connect your phone to your computer. On your phone, tap the 'Charging this device via USB' notification. Under 'Use USB for,' select File Transfer.
You came here because you obviously have troubles transferring files to your Android device via USB. Don't worry, you're not the first person to experience this issue. You probably get the following error message:
Lucky for you, there are only a handful of options for you to try, and you will be able to transfer files within minutes. So, without further ado, here is what you need to do to make Android file transfer work again and pass all error messages.
If you are on a Mac, go ahead and download the Android File Transfer for Mac if you haven't done that already.
How to get Android File Transfer to work
Best free roulette app. There are a few reasons why you might be getting an error message when trying to get files onto your device:
- USB cable doesn't support file transfer
- Device not set up to accept files via USB
- You have Samsung's Kies file transfer installed
- Your micro USB port is broken (sorry, can't help you with that one)
Step 1 – Enable file transfer on your Android device
This is the very first thing you must do to ensure that transferring files to your Android device is even possible.
To enable USB file transfer go to 'Settings' > 'Storage' > Tap on the three vertical dots in the top-right corner of your screen > 'USB computer connection' > Tick the box next to 'Media device (MTP)
If you think that your problem with transferring files is software-related, try connecting your device via USB to your computer, check 'Camera (PTP)' and uncheck it again. This seems to work for some people.
Step 1.1 – just happened to me on stock Android Marshmallow 6.0
Updating the post right after fixing the issue on the Nexus 6P.
If you don't see the above-mentioned options in your Storage & USB settings, make sure to enable USB debugging and then follow this tricky sequence (screenshots also below):
- Detach USB cable from device
- Enable Developer Mode by going to Settings > About Phone (at the very bottom usually) > press on Build Number repeatedly until the pop-up appears
- Go to Settings > Developer Options
- Enable USB debugging
- Lock device (turn screen off)
- Connect your phone to your computer using a USB cable
- Unlock your Android device
- Swipe down to see notifications and press on 'USB for charging'
- From the pop-up, select File transfers
- Lock the device and unlock it again
Using this method you are, basically, allowing your phone's security mechanisms to accept file transfers via USB. For some reason this option is not available without enabling developer options, although it should be.
This method should work on all Android devices running stock Marshmallow 6.0+, like the new Nexus 6P or Nexus 5X. Please let me know in the comments if these steps worked for you, and which device you were using, so I can improve this guide for all those who might have the same problem in the future.
Step 2 – Uninstall Samsung's Kies file transfer software (skip if not installed)
Samsung's file transfer software often causes interferences with the native Android file transfer. To uninstall Kies you will need to download the installer first (clicking the link will start the download), and just then select the 'uninstall' option within the file package.
Step 3 – Check your USB cable
Not all USB cables are created equal: Some are able to transfer files, some are not. To make sure you got a cable that can do that, go ahead and take the cable that came in the box together with your Android device. There cables are usually able to handle file transfers.
In case you can't find another USB cable to try if it works, you should check out AirDroid. This nice piece of software allows you to transfer files to your Android device with no cable at all.
If you really need a USB cable for file transfers, get yourself a good cable, it will last you quite a while (and they are quite cheap as well).

You try to plug your mobile phone, SD card, USB flash drive, or hard disk into the computer for transferring files, photos, or movies, but a message saying 'A device attached to the system is not functioning' pops up to remind you that an error occurs. However, you are not sure what is going wrong.
Have you experienced this situation before? If you did have this irritating problem, no worries, this guide will tell you how to fix 'A Device Attached to the System Is Not Functioning' error on PC when connecting with iPhone, Android, or external storage device.
1. Fix A Device Attached to the System is Not Functioning on iPhone
Before going into the solutions, we'd like to tell you why your computer says 'a device attached to the system is not functioning' when transferring files from iPhone XS/XR/X/8/7. The error is the compatibility problem.
Since the introduction of iOS 11, Apple changes its default media format from JPEG and H.264 to HEIF (High-Efficiency Image Format) and HEVC (High-Efficiency Video Codec). As the name suggests, the new formats optimize the storage size but maintain the similar quality of the photos and videos as the original JPEG and H.264 formats. Though the efficiency has been improved by the new format, they are not compatible with every device, for example, Windows PC doesn't support HEIF(HEIC) and HEVC without corresponding codecs.
When you copy the photos or videos from iPhone to Windows, iOS devices will automatically convert HEIF photos and HEVC videos to JPEG/H.264 formats. The conversion triggers the error that says a 'device attached not functioning'. Here we've collected five solutions to help you fix that.
Solution 1. Keep Originals When Transfer to Mac or PC
Since the iPhone 'a device attached to the system is not functioning' error happens when HEIF/HEVC files are converted to JPEG/H.264, if we skip the conversion step, the error should be gone.

Step 1 Open Settings on your iPhone/iPad.
Step 2 Scroll down and tap on Photos.
Step 3 Scroll down to the bottom and select 'Keep Originals'.
There, you have enabled transferring the original format of the photos and videos to the Windows PC. But to HEIC photos on PC, you need to download HEIF codec on the computer. Or you can use a HEIC converter to convert HEIF(HEIC) to JPG/PNG.
Solution 2. Use DoTrans to Copy Photos from iPhone to PC
Since directly copying files from iPhone X/8/7 to Windows PC can trigger the error 'a device attached to the system is not functioning', you can copy files from iPhone/iPad with FonePaw DoTrans. This professional iOS transfer tool for Windows 10/8/7 PC can help you transfer HEIF photos, videos, contacts on iPhone/iPad to Windows without any error.
