In conclusion, while the Samsung Galaxy Tab 10.1 may not come with a built-in USB port, the availability of these new USB adapters and the 30-Pin to USB Charging Data Cable significantly enhance ...

Samsung used a USB cable for some of its earlier tablets that, on the tablet end, looked identical to an Apple 30-pin plug. However, it was not the same and not interchangeable.

When using an MHL cable with a 5-pin Micro USB plug to send content to a large screen via HDMI or VGA, an 11-to-5 pin adapter was required (see MHL). See Samsung 30-pin connector.

The Lightning to 30-pin Adapter is no exception, containing several chips required to allow that flexible functionality to be passed through to devices using the old dock connector design.
