But to use it, you need a device with a usb port, for example a computer, which is not always at hand, unlike a phone / smartphone / tablet, etc .. So how can you connect a USB flash drive and other devices (mouse, keyboard, joystick, printer, etc.) to our phone / smartphone / tablet, etc. This will help us otg cord. What is OTG? USB OTG (On-The-Go) is a further expansion of the USB 2.0 specification, designed to easily connect USB peripherals to each other without the need to connect to a PC. For example, to models of smartphones and phones that support USB OTG, you can connect some USB devices. Usually, these are flash drives, keyboards, mice, and other devices that do not require additional drivers. Pinout and pin assignment The first contact is power supply +5 Volt. Together with GND, it provides power for the device to be connected (flash drives, memory cards, etc.) The second contact is Data-. The third contact is Data +. The fourth contact is an OTG contact. It closes with GND to transfer the smartphone / (any device supporting OTG with a similar pinout) to the host mode - supply to the voltage connector. The fifth contact is the GND (Ground) contact. Theme Assignment Not all devices support OTG and, as a rule, support is not indicated in the specifications, so I created this topic. The topic will be a list of regular phones and smartphones that support this feature or do not support it. Since there are a lot of phones and smartphones and I am not able to give a complete list due to the lack of information about support, let's do this: you answer the questions by numbering the list like mine:
You can also write that I managed to connect via OTG: a USB flash drive (specify the file system), a mouse, a gamepad, etc. Upload photos, videos, descriptions, etc. Next, a list will be compiled, which will be constantly updated. Please do not stand aside and help in the common cause. Answer the question from me +: happy: and: thank_you: P.s .: if you notice that the model declared under the spoiler "Yes" does not support otg, please inform. Supports OTG(initial otg support)
Supports OTG, but ...(customization is required, or there are other nuances)
Does not support OTG(there is no support at all, or only at the moment, but it will probably appear)
On most models with OC android supporting OTG, an android version 4.x.x is installed with a kernel version 3.x.x (versions can be viewed in the settings). But it happens that even with these characteristics there is no OTG support, therefore, if this function is important to you, then it is better to check its availability before purchasing.

User [offline] Group: Banned Messages 64 Check in: 10.05.09 HTC HD2 Reputation: 3 | Good evening. The other day, I became interested in USB otg for my nexus 4. The problem is that I don’t know how many ohms to set the resistor to 4 and 5 contact. 4 pda write that 10 ohms. For MHL you need about 90 kOhms! I took the otg adapter from the tablet Tab 1 from my brother. The multimeter shows the resistance of the resistor only in 2000k mode, where it gives the number 0.2. At 200k and below shows nothing, that is, it gives a unit to the left. I can not figure out how many ohms you need for a circuit. If you think about it, then each device eats an amp as much as it needs. Yes, and each device has a certain amount of voltage output. Then the resistance can be chosen according to the school formula I = U / R. You need to find out the voltage that the nexus 4 gives out and calculate the maximum number of Amperes you need. Calculate the border taking the example of HDD. There will be resistance. But it seems to me that everything is easier. Is it so? -------------------- SE T630 =>Nokia 6681 =>Nokia 3500c =>Nokia 5130XM =>HTC HD2 |

Visitor [offline] Group: Active users Messages 17 Check in: 23.07.08 Reputation: 2 | It so happened, I became the proud owner of this device CRESTA CTP 810 And it seems to work well for its money ($ 100), but a sad defect was discovered (or the manufacturers might have conceived it). There is a full USB connector (OTG) on board that immediately wanted to connect a USB flash drive, Screw, 3G, etc. but unfortunately the tablet saw only the mouse and keyboard, and when connecting other devices, it hung tight or did not react at all. ((( In this topic, I want to describe how I achieved a normal connection of flash drives, and any other devices. Inside, the animal turned out to be an ordinary Chinese, even though it was produced by a Dutch company. After a detailed study of the insides of the device, it turned out that the power coming to the port is not at all 5 volts but just 3.7. (sad) It was possible to make external power from a flash drive from charging (there was just 5 in.) As described in many forums. But then the flash drive can only be used stationary, and this is no longer good. Rummaged through the Internet and not finding the scheme of the device, he decided to make a dc-dc converter (from 3.7 to 5) and place it inside the animal. The board itself could be soldered, but it was too lazy to go for the details, so I took the converter's handkerchief from portable charging. We unsolder the board itself and see where the contacts go. On those contacts where the battery is soldered, you must submit 3.7 and where the connector gets 5 in., Everything is logical. That's the way a miniature circuit for charging, it is suitable for our case http://me1.at.ua/publ/1-1-0-5 But the finished version http://hobbyking.com/hobbyking/store/__788...rSearch=booster Solder the input (3.7 in) shawls to the tablet ("+" and "-"). You can solder to the same USB (I will be powered by the WI-FI module, it was also 3.7 in.) We tilt the USB connector of the “+” connector from the native power supply. I just cut the track with a stationery knife (at any time you can solder everything back as it was). And solder the exit handkerchiefs to this leg (at the exit, I soldered only “+” Since the minus is common). Hooray! The connector is now 5 volts. Everything is now left to put the scarf inside. Its envelope allowed to shove it between the battery and the mat. Board and secure on double-sided tape. We collect and check. Immediately after connecting the flash drive, she blinked happily, and the system recognized the Flash drive. Profit The 3G USB modem was also tested, which the system determined without any complaints. There is no complete process, everything is shot after installation. Sorry for the quality of photos. On other devices, you can repeat a similar operation, also with a mini USB, look for instructions on disassembling your devices on the Internet. All that is written here is not an instruction, the author is not responsible for the damage done to your device. My first post, do not kick much.

I misunderstood the essence of the answers by the points: 3. Android version- does not matter, but you can activate it even on the stock firmware. 5. 3.4.0-perf-gf43c3d9 # 1- This is a stock kernel, which I have installed, and which does not support OTG. We need another, for example the core of Franco. And as a supplement, it is possible to install the OTG recovery version (more reliable and stable, which works in the recovery menu), for simple copying / transfer between media. Otherwise, everything is OK. Once again, I apologize for being misleading. ;) -------------------- A consensus must be sought, Alexey Feofilaktovich, a consensus! © Shirley Myrly |

There are many reports that this OTG model does not support, there is no support for OTG in the official specification. Support in the MTK MT6589 processor itself: --- (Google translation from the bourgeois forum) OTG is supported, but depends on if it is included in the OS. Not all phones with these chipsets will be included. With the help of a tambourine, I did not see people who raised OTG on this model-mention, I dug up the whole Internet. |
