[QUOTE="BigAl07, post: 71870, member: 13808"] It's important to note that there IS a difference between a "regular" data cable and an OTG cable. You can not tell the difference from looking at the cable unless you dig into the connector to see how it's wired inside. Even when you take the cable apart there is only a single difference between the two but it is a significant difference. It's all in how the devices determine who is Host and who is "just" a device. *Note: Pin #4 labeled as "Sense" is also known as the ID Pin and it's left OPEN/Floating in a regular USB Data cable. For OTG the ID Pin is connected to the Ground Pin and the device handles this differently internally. I'm not sure why the image did NOT show up in my original post but none-the-less here it is. It should help make sense of what I was trying to explain.... [IMG]https://qph.fs.quoracdn.net/main-qimg-b388b2fddb25b44e77e868c4346ac25b.webp[/IMG][ATTACH=full]7811[/ATTACH] [/QUOTE]
