USB OTG (On the go)

Galaxy R supports USB OTG (On the go). You just need a OTG cable.
You can also use a Nokia Usb OTG (On The Go) Cable.
You can get the Nokia Usb OTG Cable for less then 2 euro on Ebay and Amazon.
The Samsung Usb OTG Cable costs much more.
The Nokia Usb OTG Cable just has one disadvantage, it has a "micro usb type A" connector.
The Samsung connector is "micro usb type B" .
But the difference between "micro usb type A" and "micro usb type B" is just that type A is not rounded, type B is rounded.
So you have to "round" the Nokia type A with a File tool http://en.wikipedia.org/wiki/File_(tool), transforming it into a type B.
It works, I have done it.

I've got Acer tablet with full-size USB and input language can be switched by Shift+space there. If this doesn't work for you, look for other software keyboard that supports hardware keyboards (sounds weird, but yes, SW keyboard needs to support HW keyboards).

yep. It is like using usb-keyboard with WM device. I tried many free/kracked keyboards from Market - no results for now.

Great stuff! How about MHL (HDMI adapter) support? Does it support?

I saw the cable which is compatible with models:
Samsung Galaxy S II i9100
HTC Sensation G14
HTC EVO 3D
HTC Flyer
Samsung Note
Samsung i9103
but some users said, that there is no image on TV, just sound.

can i just buy an otg cable for samsung galaxy s2 and instead use it for galaxy r???
will the otg cable for s2 work/compatible for R i9103???
thanks!!!

can i connect this USB PORT HUB with the OTG CABLE to my galaxy R.
m a bit confused on how would the USB PORT HUB get the required power?
would it draw it from the phones battery or i need an external supply?
thankss!!!

grv2, you'll need an external power for hub.

thanks buddy
can u suggest me a working usb hub with external power....
cos all m getting is usb hubs for laptops which obtains its power from the laptop alone....
thank u very much....

anybody tried MHL adapter that comes for SGSII in our SGR....??

You can connect everything that doesn't need too much power:
Camera, USB-sticks and even other Phones are working perfectly
For HDDs you would need extra power supply via USB-Hub with external power supply or even a USB-charger should do the job (but I haven't tested it yet!). You could connect the 2nd power only USB connector (which is shipped with many USB-HDDs on an Y-cable) to the powered hub or the charger. e.g i've won a portable USB-Charger from HP at VMWorld, i have to try to power an HDD with it - thank you for reminding me with our question !

Just search for "USB-hub external power" or "self-powered" , gets me several results from Amazon
Like:

can this fone deliver enough power to the self powered usb hub to work???
i really doubt that....
thanks!!!

Self-powered means it needs no power from the main hub, but has all the power itself (from its own power supply).
There would hardly be any use for other hubs ;-)

You need a kernel with USB OTG support. SebastianFM's kernel, here
The Micro Usb connector has 5 pins inside. In standard data cables that comes with the phone, only 4 pins are used. When the unused pin is connected, the cable becomes an OTG cable.
Pin 1 : VCC pin, +5V Power supply, COLOR : RED
Pin 2 : D-, Data- Signal line, COLOR : WHITE
Pin 3 : D+, Data+ Signal line, COLOR : GREEN
Pin 4 : This is the pin which is not used in standard data cables, we will "SHORT" it to pin 5 to make an OTG CABLE
Pin 5 : GND, Ground Supply
These colors are UNIVERSAL in USB connectors, this means the red is always VCC, black is GND and the other two always perform the same action, unless somebody deliberately connects the colors to different pins
Warning : I'M NOT RESPONSIBLE FOR ANY DAMAGE ON ANYTHING. (YOUR PHONE, DATA CABLE, USB CONNECTOR, HOUSE, FERRARI ETC.) IF YOU AVOID ANY SHORT CIRCUITS, AND COMPLETE ALL THE STEPS AS I EXPLAIN THERE WILL BE NO PROBLEM. AND THIS TUTORIAL SUPPOSES YOUR PHONE AS AN HTC PYRAMID
IF YOU ALREADY HAVE AN OTG CABLE, YOU DON'T HAVE MUCH TO DO.. YOU GO TO 2
1 ) THOSE WHO DON'T EVEN HAVE AN OTG CABLE START HERE -THESE STEPS REQUIRE EXPERIENCE ON SOLDERING
What you need:
1)A "MICRO USB B" head. (Can be obtained from an old charger, data cable)
2)USB A Male to USB A Female Connector : These Connectors
3)USB Cable (A short one is enough)
4)A sharp knife,etc.
5)Soldering Kit
6)Hot Glue
7)Tape
8)Some experience on soldering
STEP 1 - The first thing yo need to do is to SLICE two sides of the plastic cover of the micro USB connector, and clean the glue under it. You will need the plastic cover later!
HAVE A LOOK AT THIS VIDEO TO UNDERSTAND CLEARLY
STEP 2 - Once you reach the pins under the glue, you can get your soldering iron now to start soldering.
Matching cable Colors and Pin NUMBERS AGAIN : 1-RED, 2-WHITE, 3-GREEN, 4-NO CABLE, 5-BLACK
STEP 3 - If you did soldering (or cables are already soldered to pins--if you're using a data cable) now you need to SHORT CIRCUIT the EMPTY PIN (PIN 4) and PIN 5 (Black Cable). You can use a very short piece of cable to do this. NOW YOU HAVE A "MICRO USB B" CONNECTOR WITH OTG SUPPORT.
STEP 4 - After you completed the soldering, and IF you are sure you made no mistakes, apply HOT GLUE. Wait for it to get cold and hard, then cover it with the plastics you sliced before. You can use cheap quick glues to do that. How the connector looks after all depends on your creativity and ability
STEP 5 - Cut the cable of the USB A MALE to USB A FEMALE connector at 20-25 cm from the female connector. Now you can connect USB Female A connector, Micro USB B connector, and USB Male A connector
STEP 6 - First connect the matching colored wires of USB FEMALE A connector and Micro USB B Connector (red to red-white to white-green to green-black to black). Now you've a working OTG cable, but without an external power connector.
STEP 7 - To connect the "USB A MALE" connector,which will be the external power to the OTG, you only need to connect red and black colored wires of it (the +5V and GND wires) to the matching colors of the other two cables you connected before ("MICRO USB B" and "USB A FEMALE"--The OTG CABLE you've made). If you connect white and green wires of "USB A MALE" connector, YOUR CABLE WILL NOT FUNCTION. DO NOT CONNECT WHITE AND GREEN WIRES OF MALE USB A CONNECTOR.
You can use soldering iron to strenghten the connection between wires. Or you can just use tape. It's up to you. Just be sure that there's no possibility of short circuits.
You need to use tape for each color of wires to prevent short circuits.
AGAIN : Be sure that you've made all the steps carefully and correctly, and avoided any short circuits before using your cable. The only short circuit should be the pin 4 and pin 5 of MICRO USB A connector
AND YES IT'S DONE, YOU CAN USE YOUR CABLE NOW
2 ) THOSE WHO HAVE USB OTG CABLE AND JUST WANT TO CONNECT AN EXTRA USB POWER CONNECTOR--START HERE
You need :
1)MALE USB A CONNECTOR with 100-120 cm cable -- lenght depends on you, should not be much longer than 2 meters(standard usb connectors) (U can get it from any data cables, old USB mouse cables, controller-joystick cables.. Just cut the cable at 100-120cm from the connector)
2)Your OTG Cable
3)A Sharp Knife etc.
4)Tape
5)Soldering kit (optional--if you want to strenghten the connections of wires)
STEP 1 ) Cut the USB OTG cable in the middle.
STEP 2 ) You only need red and black colored wires of "MALE USB A" connector, which are +5V and GND.
STEP 3 ) Connect the matching colors of your OTG cable again, but this time also connect the "MALE USB A" connector's red and black wires to the matching colors. WHITE and GREEN wires of this connector should not be connected. Otherwise the cable WILL NOT FUNCTION.
You need to use tape for each color of wires to prevent short circuits.
BE SURE THAT THERE'S NO POSSIBILITY OF SHORT CIRCUITS AND YOU'VE MADE NOTHING WRONG
You can also connect SHIELD WIRES of each cable to each other. But i'm not sure what actually it does. If you test it, please post your experiences.
What is Shield Wire:
The USB cables actually also have "SHIELD WIRE". My 2.5" external LG HDD does not work with the cables without shield wire, but many products should work. Shield wire is the one silver colored wire surrounding the other four colored cables and aluminium foil. It is connected to the outer silver colored parts of the connectors. I'll update this post after testing if shield wire needs to be connected,too. For now i use my cable without it, but my hdd does not work. All others (usb mouse, usb flash drives, joystick, hub, my sony e443 Walkman , PS3 Dualshock 3 Controller etc.) work. I don't know if the reason why my hdd does not work is that wire. Will test it by monday and upgrade my post.
My own made cable is attached below, not perfect, but good, working fine

Sir, I have done exactly what's in the guide for having an otg cable and attaching a usb male for external power. But I am facing a little problem and that is when I connect power to usb male first, but without attaching to my Tab, and I connect my pen drive first, it doesn't get powers as the led doesn't blink. But it does blink only at the moment I insert the pen drive into the female usb. Now I did a different thing, I connected micro usb port to my Tab, then my pen drive and then the power male usb cable, it works fine. But I am getting confused that is my pen drive getting power from that attached usb male.

I sometimes face the same problem when i want to use my external HDD device. But its not a problem at all. I think usb male power has some difficulties on supplying enough power to both phone and HDD. It works by connecting HDD first, then USB male to power, and then phone. This order may change according to your charger, device, and phone

You may have damaged it? You sure you connected all the wires correctly? Because all these colors are universal and there shouldn't be any problem once everything properly done.

Question.. on another thread someone mentioned using a 100k ohm resistor between pins 4 and 5 for "charging" while using OTG mode. Any particular reason why you didn't include this? reading your comments it appears like its not required but just curious.

Some newer phones (like s3) do not charge while using a Y cable. For ex. the controller is connected to Y cable and it works with the phone, but the phone is not charged although the power is also connected to the Y cable. This is annoying because playing games consumes battery ver quickly I (am not sure but) think the reason for including a 100ohm resistor is to enable charging and host mode at the same time on such phones. On Sensation there's no need for it because this cable just works perfect for Sensation. Charges and hosts at the same time.

Great info and instructions, now the only answer to the burning question I have is.......
..... Has anyone... Anyone! at all! managed to make a OTG Cable with a USB power plug, using the correct 'resistor' value while still using the phones stock 'unrooted' JB 4.1.2 rom, and stock 'kernal' not patched in anyway for the Samsung Galaxy Note 2.
Although there are products on eBay said to do this job, and have been reported to work by others, the sellers that offer these adapters are all based in China, and will not trade/sell to Europe at all.
If anyone has a solution around this problem, sharing there knowledge would be great.

Nokia OTG cables are not Micro B connectors but Micro A. So The OTG cable for N8 will not fit into our sensation or other android phones. You can see the difference between Micro A and Micro B here :

U can use Chainfire's StickMount app free on playstore to see if your flashdrive is connected. If it shows no drives connected then check your connections, optionally using a multimeter. Check the 4th pin is shorted to 5th one.

If you have a multimeter it will be good to test of course. If you're sure that u coonected all wires without any wrong short circuits there will be no problem, no damage for the phone

USB Host / OTG working (UPDATE: now self powered)

Update October 28,2012:
h8rift figured out how to enable full OTG support with 5V power, no need for y-cable anymore!
You need to use a modified kernel for self powered OTG. Stock kernel has OTG but needs a y-cable connected to 5V power source, as explained below.
To enable powered OTG, you will need to use one of the following:
CM10 Nightly builds: http://forum.xda-developers.com/showthread.php?t=1790032
King Kang ROM: http://forum.xda-developers.com/showthread.php?t=1959099
rohan.kernel: http://forum.xda-developers.com/showthread.php?t=1892108
For Sense ROMs: http://forum.xda-developers.com/showthread.php?t=1967897
______________________________________________
To use OTG with stock kernel:
Here's what you need:
-an OTG cable
-a USB Y-cable
-a usb perhipheral (eg: mouse, keyboard, thumb drive, etc)
The key to this working is 5V on the uplink to the phone. Most usb hubs do not supply 5V on the uplink! This is why I suggest a Y-cable.
1. connect the perhipheral device to the Y-cable
2. connect the y-cable to the AC power adapter that came with your phone
3. connect the other end of the y-cable to an OTG cable
4. connect the OTG cable to your One X
Here's a screenshot showing the mouse pointer:

Notes:

-usb-hid seems to be built into the kernel, no modules need to be loaded
-usb storage works, but has to be mounted manually
-tested on stock kernel and scrosler's cleankernel

Cool. Kinda sucks that you need a separate 5v source.

^^yeah, there's not much you can do about that. I'm pretty sure there's no way the phone can supply the power.
Also, I can confirm usb storage works.
I attached a thumb drive and manually mounted it:
mkdir /mnt/usb
mount -t vfat /dev/block/sda1 /mnt/usb

Any proper OTG cable (I got mine for like $3 on ebay). In an OTG cable, pin 4 on the micro usb side is grounded. This is how the device automatically senses that it should enter host mode.

But it has a brushed aluminum theme, no? So it's not stock.

The Galaxy S II supplies power for USB host with a OTG cable ... stock
This is like the way you have to do it with a TouchPad, who carries around a portable USB power supply? If HTC wasn't going to give a MicroSD slot, you would think USB OTG would be officially supported.

Does the phone at least charge in this mode so its somewhat useful?

Oh.. didn't realise there was such a thing.

It doesn't charge while in host mode, but I think that function might be enabled with a little kernel hacking.
I'm not familiar with the hardware yet, I just got this phone a few days ago. The USB controller is likely part of the soc. There would be a phy between the main chip and the USB port. The phy is where voltages would be controlled. There are many different phy's available, each has different capabilities.

I'm saying that the usb phy, which is a physical chip that controls the micro usb port, might be able to be programmed to allow charging while in otg mode by modifying code in the kernel. But I don't know enough about the phone's hardware.
I think, but don't know for sure, that there is a signal in the usb cable that tells the phone whether it's connected to a normal usb port or an AC adapter. The phone will draw a small current if it's connected to a computer usb port and a larger current (to charge quicker) if it's connected to the wall charger. Perhaps there is a resistor or short between D+ and D- lines? I don't know, more research is required. If anyone knows, feel free to contribute here.
What I do know is that when you connect the otg cable, a pop up comes up saying charging is disabled.

The at&t S3 supports USB OTG w/o external power. Plugged in a mouse, it worked. Keyboard same thing. Plugged in SD card reader, S3 mounted the card and file browser opened. It was pretty cool.

Basically all Samsung Android phones from Galaxy S2 onwards support USB OTG out of box.
HTC follows Google's route that doesn't support any USB OTG out of box (Nexus N7 doesn't have USB OTG OOB) for whatever reason.
The only reason I'm interested in USB OTG is to use an external storage when I'm traveling, e.g. on a flight. The requirement of an external 5v supply basically kills it for me. It would scare the heck out of fellow passengers when they saw me plug some wires to the phone connecting to some external battery pack and storage card

My reason for wanting otg is so I can backup and review photos from my DSLR camera when I'm on trips. The external power requirement is an annoyance, but I can easily deal with it back in the hotel room.

I wonder what the current threshold is to get the USB controller to think it is charging?
Would this work: attach a watch battery of the correct voltage and a resistor to limit current draw to one side of the splitter and have a device (battery, resistor, splitter, OTG cable) that's not all that big.
I too would like to access digicam SD storage via my phone for minor edits and uploading.

LOL that is worth doing just for the lol involved make sure you wear a turbin on the flight too for added effect and sit there speaking gibberish the whole time as well! Actually you should pull the battery supply from your turbin HAHAHA
On a serious note: I can't wait for OTG to hit our device either we really could use it and rohan32 is trying to work it into his new kernel possibly.

OTG Cable max length?

Hi
What is the maximum length can an OTG cable have?
if I make an OTG cable with a length of 1-2 meters, will it work? ,
the load is just a flash drive .
Thank you.

The length of the cable which you can create is only limited by your resources and by the ability for the electricity to go through it. Therefore, you could make a 2 mile otg cable if you knew how. So to answer your question, if you can make one yea it will work.

today I made an OTG Cable (1 meter ), I attached it to my LG G3 but it was not recognized by the phone, I used the multimeter to check if there was any voltage coming out of the Red and black wires but there was 0 voltage?
is there something I should do in the Software of the G3 to enable OTG cables ?

No clue, this is a gs4 forum. The most likely problem if there was no voltage would be something wrong with the wires.

Yes, using the stock sammy ROM it worked with no extra software or messing about (probably with other roms too).
However, in the sammy rom UMS (usb storage when connected to PC) didn't work how I wanted it to, so I migrated to a CM rom where UMS will work.
However with CM, usb OTG needed a little "help", and I had to use chainfires Stickmount app to re-enable it, but having to option to use both (albeit with an enabler-app) is better than only one or the other.

Please i ve an OTG cable ba my s4 verizon hyperdrive ROM does nt recognize it. Pls help me awt

I'm not familiar with the Verizon variant, but a quick search brought me to the XDA thread for Hyperdrive KK RLS21, and apparently it's pre-rooted, yes?
That being the case, I would try using either Stickmount, by Chainfire, or perhaps USB OTG Helper.
(I note one reviewer of USB OTG helper actually states that it only worked for him when he used both apps in conjunction, but doesn't state his specs so we can't make any real judgements there)
As root-only apps, when you try them, be sure that you grant them superuser permissions (you should also see a little notification of this after every reboot also).
Finally, be careful careful careful about letting the OTG cable disconnect, or fall out of the USB port of your phone... The device will see this as it being disconnected without unmounting, and it does not like this, not one little bit...
I've had a right hell of a time getting OTG to work on my device lately, so I don't speak from technical knowledge, only end-user experience, but once you get it working, be really careful to go into storage settings, and manually "unmount USB storage" every time you want to remove the OTG cable.
Hope some of this helps dude...

Thanks everyone, I got it to work, the 2 meter cable was faulty , The max length I managed to get is 1 meter, I didn't try any longer cables

Is there a limit to how many USB devices can be used at once?
For example: If I used a USB hub, would two controllers and a thumb drive all be recognized and work all at the same time?

In theory it *should* work, I've seen examples of it being used like that before but I'm fairly positive it would need to be a powered hub...?
I have a cheap, non-powered 4-way USB hub, when I get home from work tonight I'll try it out with multiple USB devices and let you know.
This forum discussion seems to indicate using multiple USB devices could work, assuming your ROM supports OTG...

Game Controllers? I'm guessing you're thinking about storing games on the pen-drive and then using the controllers on your phone to make a gaming device?
I'd be very - very - interested to hear how you fair with that!
I know that some games, like San Andreas support joypads on android right out of the box, whereas others might want you to use a joypad/controller app such as USB/BT Joystick Center Gold (sorry, can't find a link to that right now).
As i said, I'd love to hear how you get on as it's something that interests me also - promise to come back & report what you find?

My purpose was to run two XBox 360 controllers via the USB hub via the OTG cable along with the thumb drive for a console game emulator. One might ask why not just try it, but I'm lacking some components currently.

Ok, that's annoying!
So I tried my device (rooted S4 i9505 using CM12.1, running Chainfire's Stickmount app to get OTG working).
Used my un-powered USB hub, with both a 32gb USB pend drive, and a microsoft USB mouse at the same time.
Each device (mouse and drive) works fine when directly connected via OTG.
However, hook them both up via the USB hub, and no dice.
If both devices are attached to the phone using the un-powered USB hub, then only the mouse is recognised - the USB pen drive is not recognised. Stickmount detects zero active mounts.
In addition, I had some strange behaviour from the phone when both devices are hooked up..
Loooong boot times, Novalauncher not wanting to draw to the screen, and to top it off, the phone no longer recognises my SD Card...
I don't actually have a powered USB hub to test with, so I can't really go any further for you on that score right now Tommy.
My initial "suspicion" is that you'll need a powered hub if more than one device is going to be used at a time.
I do happen to have two PS2 joypads, plus a joypad-to-USB adapter (so I can play emulator games on my PC)...
.... so later tonight I'll try hooking up 2x Jopypads>Adapter>OTG Cable>Phone & see if they can be detected.

Thanks for taking the time.

@BigJim.T32
By the way, you seem to think power is the issue, I doubt it. If anything, the phone battery would die quickly, but devices should be recognized. More than one device should be recognized. In fact, the phone is lost and doesn't know what to do with all things connected (as you've said). That sounds like OTG limitations to me. OTG was never designed to run so many things at once is my guess.
OTG functionality was probably just a nice afterthought feature to allow one small connection. Anyway, what do I know? I'm just guessing based on your tests and statements. That doesn't mean that's the way it's going to always be, but that's probably the way it's going to always be with the GS4.

I would have imagined you're correct; And you seem to hit the nail on the head with your analysis - when both devices were connected to the phone via OTG, the mouse took priority, over both the regular SD Card and the mounted USB pen drive, leaving the phone unable to detect either of the two storage options. Came as a surprise when I connected both deices to the phone, checked CM's file manager and couldn't even see my micro SD card in the list, even after a reboot...
The reason I initially suspected that a powered USB hub would be the next place to try (and I hasten to add it's only a suspicion, I have no experimental experience to go on) is only because I've seen photos of other, older Sammy phones simultaneously using both a mouse and USB drive connected via OTG on other sites/forums... And I figured, if they can do it, we *should* be able to do it too! :laugh:
Sorry, I've not had chance to test with my cheap-ass playstation 2 joypad adapter yet (been at the GF's all weekend - boo!) but I promise I'll test it soon as I can and report back here; hell, I want to know for my own benefit too.

Maximum length of USB 2.0 cable:
USB 2.0 Connectors (Plugs)
The 2.0 specification limits the length of a cable between USB 2.0 devices (Full Speed or Hi-Speed) to 5 meters (or about 16 feet and 5 inches). In other words, you cannot just connect a bunch of extension cables together (like taking a 6 foot cord and extending it with 4 other 6 foot extension cords) and run them 30 feet to another room. However, you can connect a 6 foot cable with a 10 foot extension cable for a total of 16 feet, which is below the maximum cable length for USB 2.0.
Back to Top
Maximum length of USB 3.0 / USB 3.1 cable:
USB 3.0 Connectors (Plugs)
The 3.0/3.1 specification does not specify a maximum cable length between USB 3.0/3.1 devices (SuperSpeed or SuperSpeed+), but there is a recommended length of 3 meters (or about 9 feet and 10 inches). However, the biggest limitation to the length of the cable is the quality of the cable. Results may vary, but with a high quality cable you should be able to go beyond 3 meters. However, to ensure you achieve the best results possible, use an active cable when going more than 10 feet (3 meters).
I got this from some website - Google is your friend! :good:

Stupid question time - how to connect Pixel 2 to a PC?

This is my first USB C phone. How do I properly connect it to my Windows 10 computer that only has USB A ports?
I have these cheap USBA/USBC cables. I don't remember where I got them, but they're probably the "cheap" kind. When I use these to connect to the PC, Windows does not detect my device at all. No unknown device, no USB driver installation, nothing.
On the phone side, it does charge. However, I don't get the USB notification to toggle between charging/MTP/etc. I toggle USB debugging on and off and reboot, and there are no changes in behavior. I simply get a battery charge and cannot get any other interaction between device and PC.
Are my cables the issue? Do I need to buy a "legit" USBA/USBC cable?
The Pixel 2 came with a USBC male/USBA female adapter. I wonder if a USBA male/male cable would work? That's an odd cable if they even exist...
How is everyone else connecting their Pixels to PCs?????? I can't figure this out.

The adapter is for USB OTG, to connect a USB stick to the phone for example, or transfer data from your old phone.
Get a decent A<>C cable, they are not that expensive. Or, what I did as well, get some Micro-USB <> USB-C adapters (like these) and use your old (decent) Micro-USB cables. I got these for the charging in my car, as I have mounted the cable behind my dashboard, and I want to be able to charge Micro-USB devices as well.

Just buy something like this:
https://www.amazon.com/gp/aw/d/B01A...sb+c+cable&dpPl=1&dpID=31vbRV42GGL&ref=plSrch
Personal note: I bought a few cables when I purchased my old Nexus 5X. Two brands. Anker and RavPower.
Skip RAVPower, the two I have started presenting issues, loose type C port~
I'd go for Anker again.

My Pixel 2 didn't come with an A to C cable, I had to buy one from Google, and I just received it today.

I has all kind of weird glitches when I used USB 3.0 A to C cable.. all glitches disappeared when I switched to USB 2.0 cable.
So this is something to keep in mind.
