You need a USB Host to go cable - they are pretty cheap off of ebay.
USB hard drives don't always work - at minimum you will need a powered hub.

i know wht USB on the means but how do i enable it. i have tried connecting with a pendrive with the help of the USb on the cable but it does not show .

Once you plug your on the cable in the phone will inform you that usb connecter s connected. Whatever you plug in at the other end of otg cable work run unless it is not supported.

Just plug it in and look in My files. It will show as usbstorage.

I have an official samsung OTG cable, it works fine on the SGS2, but doesn't appear on the Galaxy Note under usbstorage.
Anyone else out there having similar problems?

i had grab some ebay OtG but after unmount and remove the OTG it causes wakelock which drain alot of juice.

I am also facing problems with OTG . when i plug in the cable thr is not msg nor anything happens in phone. please could any one tell me how to enable it may be with kernel or custom rom or may be anything else.

I also want to know this as well,I have spent considerable time yesterday trying to make this work but no luck at all,I would appreciate if someone could help,as I have seen a video in this forum where the guy was able to.connect a mouse to it stating that it is supported out of the box.

I was able to get it to work with a pendrive and a mouse with no problems, but I couldn't get a keyboard or my 2.5" external drive to mount.
Details:
My OTG cable was from DealExtreme for $2.30 or something.
My pendrive was FAT32 formatted.
My mouse was a basic $10 optical one.
My 2.5" external was NTFS, which probably goes some way to explaining why it didn't work even when I gave it some extra power from my desktop PC too.
My keyboard was a standard USB. I also tried a Logitech keyboard with a wireless USB dongle but that didn't work either.
I watched a whole film off my pendrive with no issues. I messed around with the mouse a bit, but the cursor moved too slowly for my taste and the scroll wheel didn't scroll webpages, which is half the reason I'd plug a mouse in anyway.

If you get no message when the cable is plugged in on it's own, chances are it is a problem with the cable. I bought a cable of Ebay which didn't work, so I bought a different one and that did.

Manual USB OTG working

Hi,
As you know, the Nexus 4 doesn't support USB OTG, meaning you can't use it with USB drives, gamepads, etc.. One reason is that the device doesn't seem to provide the neccessary 5V, the other reason is that it's not supported by the kernel.
So, I've been digging a bit, and now I can claim partial success! It's possible to supply the 5V yourself, and then activate USB host mode manually. It's a bit cumbersome, but for the beginning better than nothing. I tried a mouse and USB drives.
I should warn you that this is just a proof of concept and nothing that you'll want to use on a daily basis. Regular USB doesn't work properly while running this kernel, and I haven't checked battery consumption. Also this is based on Android 4.2.1, and if you have 4.2.2 you might not be able to make calls. That shouldn't be a problem as this is for testing only, though. Just let me say, I can't guarantee for anything, and I'm not responsible if you brick or blow up your phone.
You'll need:
- A USB OTG cable
- A USB Y cable to provide the 5V (It has two USB-A plugs and one USB-A socket.)
- My custom kernel
- Unlocked bootloader
- Android developer tools (adb, fastboot)
Load the boot image on your phone (this is not permantent):
Code:
$ fastboot boot myboot.img
Connect everything as follows (should be obvious):
- Y cable power plug (typically red) to the PC or adapter
- Other Y cable plug into the OTG cable
- OTG cable into the phone
- USB device into the Y cable socket
You need a remote shell on your device. Use adbWireless or similar to enable ADB over WiFi, then do:
Code:
$ adb connect 192.168.0.108:5555
(or whatever your phone's IP is)
$ adb shell
Now you should be on your phone. Do
Code:
[email protected]:/ $ ls /sys/kernel/debug/msm_otg/
and you should see 'mode' if the new kernel works. Now become superuser and enable USB host mode:
Code:
[email protected]:/ $ su
[email protected]:/ $ echo host > /sys/kernel/debug/msm_otg/mode
To disable USB host mode, use "none" or "peripheral". Note that at this point, I couldn't get it to go into regular USB mode. This means that MTP and adb over USB doesn't work yet.
Connect a device, and you should see more than two entries under "lsusb". Congratulations, your Nexus 4 has just recognized it's first USB device! If you install Stickmount (you have to sideload it since it's marked as not compatible), you can mount USB flash drives. Nexus Media Importer doesn't seem to work, though.
How does this work?
Basically, I just added the following line to the beginning of msm_otg_debugfs_init in msm_otg.c:
Code:
motg->pdata->otg_control = OTG_USER_CONTROL;
This enables the mode file in debugfs I use for mode switching. The next step would be to enable manual mode switching while keeping regular USB support, which shouldn't be too hard. Later down the line we can think about switching automatically on cable insertion, and maybe event getting 5V out of the device, but that would be a lot harder.
So, try it out, let me know if it works for you, and feel free to tinker around and improve what I've got!

Nice to see some progress going. Only thing that irks me is the Y cable though, kinda defeats the purpose of OTG to me...
Thanks a bunch for your work though!

You are a genius. :good:
Just connected a powered USB-HUB and a mouse to my OTG cable, flashed the kernel and typed the commands directly with a terminal app on the device.
It simply works !!!

Awesome development, one of my biggest gripes was the lack of USB OTG, I just assumed it was included as stock, that's why part of the reason I purchased this device.

This is awesome. Going to have to order some cables now. Since we have to supply power anyway, is it possible to support usb-otg + charging? Figure the phone is "too thin" anyway... I'll probably be making a 64gb microsdxc + battery case for the phone. Hello extended battery life.

Great work, I was just looking for this yesterday. Would it work with a USB dac (Assuming I had a powered usb hub)? Just asking because I think usb audio is often overlooked, and I would really like to have it.

Nice!

It would also be interesting to see if the slimport adapter allows otg pass through (their website says it does)... Then that's HDMI +charging +mouse/keyboard. Even miracast + mouse/keyboard would be awesome

I'd like to be sure I'm getting a good USB Y cable. I see a few on Amazon, some have the word 'Power' in them, some don't. Most don't have a red plug. Are there some specific characteristics I should look for in the description to know that it's suitable for this purpose?
Here's one example that does NOT say 'Power' in its description.
http://www.amazon.com/OEM-UTStarcom-USB-Adapter-Cable/dp/B002W8EDOM/ref=pd_sim_e_2
Thanks, CaptainMuon, for your terrific work!
EDIT: After reading Scorpio16v"s post (and watching his video...thank you!), I thought I would try with a powered hub, since I don't have the Y cable. Also, I used the terminal emulator instead of adb, as he suggested. YES! It worked with a USB micro sd card reader adapter (I had bought it from ebay specifically for this Nexus 4 since I knew there was no sd card slot). That required stickmount, as CaptainMuon mentioned. Then I tried a USB mouse, and that worked also. This is great!
I'd still like to know more about the Y cable, as I asked above, even though this other method worked well for me.

Wonderful!!

When I powered off my USB powered hub, neither the USB Micro SD or the USB mouse worked.

Greaaatt news and excellent development on this front sir.
I was eagerly waiting for someone to come up with a solution to this topic.
But coming back I've read in so many places that a kernel can be tweaked so as to supply 5V to the socket!!(I'm considering that is the problem here. With power supply its working).

Awesome, my one gripe with the phone is now (almost) gone!:good:
Any chance it it'll work with non-OTG cables/adapters (The plain USB host ones which don't have that extra pin)?

Just posting to thank you for all the time and effort you must of put in.

It seems to be charging in USB host mode. (In my Y cable, the +5V line connects all three plugs, so the phone gets juice too. Not sure if that's always the case.) We have to do some testing to see if it charges at normal speed, etc.

I guess, if it is supported on any other android device, it should be possible here. Would be great if someone with a DAC would try it!

Hmm, I don't know how you could make a Y cable that doesn't provide power from one end, and data from the other . It should work, but I know there are a lot of scam/poor quality cables out there, so I can't guarantee it. I've got this one:

Nice work Bro. :good:
by the way ; i can use my powerbanks as the power source. so i don't need any land electric sources.
not yet try it, i will need to find the XY cable first ( non powered USB Hub will do fine, and powered by the 11000Mah Powerbanks )

USB Port

Does the USB port have any other function other than power?

Don't think so, only power AFAIK.

I plugged it into my computer and even tried pressing and pressing/holding the button on the Chromecast but my computer didn't indicate any hardware plugged in.
I wonder if the data pins are even wired to anything internally.
UPDATE: The USB cable that comes with it may not work for data transfer, tried it with my phone and it didn't work. So I tried a normal microUSB cable but still nothing.

I tried this with a self powered USB OTG cable, just to see if the Chromecast would blink, bing, or do anything to show recognition, no dice. Also tried booting with a USB drive in, no difference.

Examining board
Based on examining the photos of the motherboard on ifixit.com...
Component EM1 appears to be a USB Common Mode Choke. That goes on the D+/D- pair which you can see routed from the USB port, so it wouldn't be present if there wasn't some use for data communication over the USB port. (Cost sensitive equipment.) The flip side of the PCBA shows TP1-TP20 (Where TP19 and TP20 appear to be GND). My guess is in that mix you have a JTAG port for programming/testing the unit initially with a pogo pin rig (evidenced by the dimples observed in each of those locations), and there might be more high/low GPIO pins where one might allow the unit to enter its USB data mode.

I own that cable from Amazon and it should work. It brings in +5v from a charger connected to the female microUSB port and then splits it to the female full size USB port and the the male microUSB port so both the USB host device and the USB peripheral device are getting power.

I also bought that powered OTG cable off Amazon and it will power the Chromecast as well as provide the means to flash the Chromecast via a USB thumbdrive. When you apply power to the Chromecast, it automatically flashed the bin from the USB drive. There was no interaction required (or even possible). Of course this was on the original firmware - if your Chromecast updated itself, you have lost the ability to root the device at this time.
Clearly the Chromecast does sense the USB drive and pulls data from it during the initial boot sequence. However I'm not sure if it would ever work for other devices such as keyboards or storage devices, etc.
I'm not sure why anyone would want to hook those types of devices up to the Chromecast however. Once you have root, you can telnet into the device, so adding a keyboard doesn't seem that important. The whole idea of the device is that you send it media from other devices and control it via that other device. Adding storage for example doesn't seem important since it can pull media off the network already (ie a NAS or another computer).
Anyway. That has been my experience with it so far. It's a long winded answer to more than just your question about the OTG plug.

I would personally love the ability to send audio out without having an hdmi TV be on through the usb somehow...

[Q] USB OTG problem on galaxy tab GTP1000

Hi all,
My interest these days is to make the USB OTG working on the GT-P1000 thing that cannot be done via a standard OTG cable. When i started searching in the internet i found a video on how to mount a sub stick on a GT-P1000 using a usb Y cable (3 males), the samsung charger (with the cable of course) and 2 sex changers (female-female USB connectors), i made my own Y cable as it's not easy to find one in the nearby stores, here attached the cabling schema (i will be grateful if someone can check it) and also my device properties.
The problem is that the tab couldn't recognize any of the USB devices, despite that i tried the overall settings of the USB Host Controller application, so can someone help me solving this issue please?
FYI my tab succeeded the test performed by USB OTG Checker,
Many thanks in advance for your help

Yes. The reason is very simple. There is no +5 V (supply output voltage) on 30-pin connector.
---------- Post added at 01:27 PM ---------- Previous post was at 12:58 PM ----------
I use the next algorithm:
1. Make initial corrections with USB Host Checker.
2. Reboot
3. Connect flesh drive to USB hub (with external supply).
4. Connect Tab to USB hub.
5. Start USB Host Controller:
Default operation mode - Set to auto-host mode
Operation mode - Auto-host mode
USB host driver - S3C HS (USB2)
Mount Points - /storage/UsbOtgDrives
6. Scanning process may take a long time - up to 10 minutes.
When scanning ends, go to the 2-nd tab of USB Host Controller.
7. Click on flesh drive and choose Reset.
8. Start USB OTG Helper.
9. Mount flash drive.
10. Profit!

Thank you MarviXDA for the detailed procedure, i will try it and let you know the result asap.

Everything is integrated. If you want to expand storage you can use an OTG Micro USB HUB an attached a USB 64GB flash drive, it will be bulky but works!

Of course it works, you can play movies directly from the USB flash drive. You will need to supply power to the USB drive, connected by wire or using a Power Bank.

Is a Micro USB Port, is the same as your charger. The one that you connect to your Tablet. Search and do some reading on how it works, is very simple but you have to understand how all comes together, there is information on this site also.
Once you have Android install on your tablet, it works the same as others Android or Tablet Devices.

Its ......Kitkat .... Android 5.1.1 version and cm-11-20161219-NIGHTLY-MLQ-tenderloin .... This is very stable ... Thanks

The ROM that you are using is from the Developer Milaq.
I installed the latest Nightly dated December 26 of 2016, of the ROM you are using.
https://milaq.net/downloads/tenderloin/cm-11.0/
After a fresh installed I connected the OTG Micro USB HUB, then connected the HP Touchpad cord charger to the OTG and finally the USB flash drive ( SanDisk Cruzer Glide 16GB). You will noticed that the USB flash indication light starts flashing and a notification on the Left top side on Android tells you ( USB Storage in USE ). Then you go to the File Manager and you will see USB Storage, when you touch it you will see all the files on the USB flash drive and you can play your movies directly from there at the same speed as if were on the internal storage. When you are done, go to setting and storage and eject the USB Flash drive. Is very simple!

I don't see nothing since nothing happens once I connect it, though if I use the cable to connect to my computer I am able to see the tablet internal drive, but not to a flash drive from tablet to flash . This is why I was asking what's exact cable type for this tablet port . I'm thinking it isn't the correct one . There so many different sizes out there. Thanks for your suggestion, much appreciated

I sent you the link to Amazon of the OTG.
Did you take the time to learn what OTG is?

Yes, I did view it but the type that goes into the tablet isn't listed . I bought one already that I assume is the correct size but with these micro usb connectors there is many different types, do you understand what I'm trying to say . Pic below is what I'm using

All the information is on this web site:

And for the second time this is the OTG cable that I have, which I posted the link : https://www.amazon.com/Adaptor-Powered-Charging-Charger-Connector/dp/B00LTHBCNM/ref=sr_1_31?ie=UTF8&qid=1486568545&sr=8-31&keywords=micro+usb+otg If you look at the specification of how it works it tells you is a "Micro Usb HUB Adaptor with Power Powered"
The HP touchpad or old devices do not offer power to the micro usb port, you need a Y adapter one to supply power to the USB flash drive and the other one for data.
That is why I said, do some research to understand the connection, which it clearly shows on the Amazon product.

Oh ok now I got you it also needs power to make it work, the tablet alone isn't good enough . See, I was hoping just a simple connector going into the tablet Micro and have on the other end usb female connector were by I could plug in a flash stick without power needed . Thanks for all your help

That will work with devices that allow power out from the charging port. The work around for old devices is the Y connector, with the connector I posted you can use a USB Keyboard, a USB mouse and a USB flash drive all at once, turning a tablet into a regular desktop PC. Like I posted your ROM will work and you can play movies directly from the USB drive with no loss in performance, with only your basic ROM nothing else is need it.
You are very welcome and have fun!

Yeah, those devises sound really good . I might just get one for that fact alone .... Though, it isn't really what I needed
