Thanks. Is the protocol in use USB 3.x though? Type C is not limited to any protocol and the Samsung smartphones are shipped with USB 2.0 peripherals. That's where my confusion stems from. I'll try a different cable though.

@YoungUn I think that USB 3.X uses 5 extra pins (see any SS (usb3.x) port, you'll see the 5 small pins before the 4 main ones) so it can send a larger current, as well as data. Because of this though, both the power adapter (or computer), cable, AND device have to be USB 3.X compatible. Essentially, the protocol is as high as the lowest component - the device and adapters need the extra pins, and the cable needs the extra wires for it. However, the smartphone might actually support USB 3.X,though I'm not sure it can make use of larger currents, you might have to look at the official documents

The cable in question is a USB 2.0 cable without these extra pins.

Yeah, so I'm guessing it defaults to USB 2.0 then. The benefits of USB 3 are harnessed using the extra pins for power delivery and data, so if they aren't connected then the system uses 2.0 as standard.
