Frequently we connect the cell phone to the PC with the USB cable to transfer files or photos. Android is usually ready to "get hooked" to the computer and allow us this task. However, on some devices you may find that it is not detected by the PC or you can only transfer photos.
This may be due to the fact that the mobile phone is configured in an inappropriate USB connection mode (there are several modes).
For example, some computers are preconfigured to load only, or in the best case, transfer photos exclusively when connected to the PC. In this case you will have problems transferring other types of files.
Change USB connection mode
Fortunately, switching between USB connection modes is simple. Once you connect the phone to the PC, slide the notification bar and Touchez on the "USB connection" notification.
This will allow you to quickly switch between common connection modes such as "Transfer files", "Transfer images", "Connect MIDI device" or "Charge your phone".
USB default setting
The above just changes the USB connection for that moment. If you disconnect the phone and reconnect it, it will return to the default or default connection mode.
Yes, in some phones it is possible to modify this default setting (only some accept the change). This way, even if you make connection changes from the notification bar, it will return to that default value.
For example, if you usually transfer files between cell phones and computers, you will want to establish the MTP connection by default.
Additionally you can find other USB connection modes that are not available from the shortcut in the status bar. For example, the "RNDIS" or "Audio source" connection.
Change default USB mode
- Open the Android system settings.
- Touchez on the "Developer options" menu (or programmer). If you can't find it, I'll tell you how to hide it below.
- Click on "Select USB configuration".
- Choose the USB configuration you want to use when the phone connects to the PC:
Load only: Obviously, it only serves to charge the device's battery.
PTP: Only to transfer photos and videos from cell phone to PC and vice versa.
MTP: To transfer files of all kinds from cell phone to PC and vice versa. It could be considered the successor of «Masive storage»On old cell phones.
RNDIS: Allows "emulate" an Ethernet connection between the PC and the cell phone. It is commonly used for development purposes.
MIDI: It could be used to connect a MIDI device to the cell phone (a MIDI keyboard, perhaps). This would create music with both teams. More information here.
Audio source: As the name suggests, it is used to transfer the audio from the cell phone to the equipment connected to the other side of the USB cable.
The "Developer options" menu mentioned is usually hidden from the factory. To make it visible go to the System Settings, Touchez on "About phone"> "Software info" and press seven times on "Build number".
Keep in mind that these connection modes only come into effect when the cell phone is connected to the PC. No matter which of them is enabled, it will not affect the load using the wall charger or AC. If you use the "Charge Only" USB mode, your cell phone will not be detected as another device on the computer. It will only charge.
After choosing the USB mode and connecting the PC to the PC for the first time, Windows you should automatically install the respective driver or drivers (if not, you will have to install them). Wait for the installation to complete to see your cell phone as a new device on the PC.
In the case of RNDIS, the drivers may not be installed. If so, you must go to the Device Manager of Windows and force a manual installation by choosing one of the drivers of Windows: «Network adapters»> «Microsoft Corporation»> «RNDIS».
