    Hello.

    I am trying to connect Gakaxy J7 ((2016), Android Version 8.1.0) with an audio interface (focusrite scarlett solo 3rd gen) connected via an usb hub powered by a powerbank.

    My phone only gets charged. There is no option to transfer data. Also I cant transfer data with this setup, when i connect 2 android phones to usb hub, because the both only get charged. When i connect my phone to pc, i get to option to choose, what i want to do with the connection (data transfer, charging, etc.)

    The setup looks like this: https://s3.amazonaws.com/cdn.freshd...5M7xg2045BugL3sKETx9RQxB7aLDw.jpeg?1586835346

    When i connect this setup to pc without the powerbank, audio interface works just fine but via pc. Audio interface is getting enough power too, which means that there is no hardware issue in the setup.

    Guys, do you have any idea, how to swith from phone charging to data transfer?

    My first thought is, does Focusrite actually support their products for use with Android devices? Their website only refers to using the Solo with Windows(needs drivers) or MacOS(no drivers needed). Do they make an Android driver app for the Solo? Your picture shows an iPhone, with the Solo connected to a USB to Lightning adapter.

    Regarding the audio interface issue, your Galaxy J7 (2016) apparently has a microUSB port and supports OTG so that port does allow for charging and data transfer, but it might not necessarily also support audio in/audio out too. If it was a USB Type-C port than yes, that has additional pins and with more functionality than microUSB.

    As for data transfers, try connecting your phone directly to the other device, bypassing that USB hub.
