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.

How is the USB OTG supposed to work?

I downloaded Nook Tweeks, enabled USB host mode and External vBus, but nothing happens when I connect a USB-stick via a micro ubs to usb converter.
Am I supposed to do something else? Or does the USB-stick have to be in some special format?

I got the same exact problem. It didn't seem to work at all.I think I'll have to order the adapter to see if the problem is the OTG cable or not

I ordered some cheap ones from DX, but since there are two of them and none of them works I'm assuming it's the Nook the problem is with.

It could be the USB-sticks are trying to draw too much power. The Nook host port will only supply low power USB devices (<100mA) and it is also best to have a fairly well charged battery. Some sticks work and others don't.
If you have a powered USB hub then this supplies the power so there is no problem. So try with a powered hub to at least see if that is the issue.

I used the same USB in this chart Nook Color USB HOST Device Compatibility List Sandisk Cruzer 8GB on CM7
I bought the Nook Color is to connect it to my camera via DSLRcontroller but so far still not successfully with USB stick.

CM7 also shouldn't give you any trouble , as long as its FAT32 and you are using a hub
can you explain what exactly have you tried and provide logs?

I didnt use usb hub,just enable the usb host mode in Nook Tweak app and plug my usb via otg cable.

Then you didn't read good enough the thread or the chart..
You need an external hub ( powered or non-powered ) to work with the sandisk cruzer.

Thanks a lot, i ll order one and try it out.
I tried to connect with my camera but nothing happened,I guess I have to try with usb hub as well

How to power 1 terabyte external usb drive

I recently got a 1 terabyte usb 3 external hard drive. I want to use it directly on my note2 via otg to backup my files and free up space on my device and microsd while I am away from my pc. I noticed my battery gets discharged really fast from powering up the drive. I was wondering how I could provide an external power to the drive or the note 2 itself while the drive is connected to the note2 via otg. Thanks guys.

Zerolemom battery. Other than a bigger battery I dont know of a different way.

I've had a couple if external hard drives that have two usb connectors. I read somewhere that once the drive starts and spins up, you really only need one connection.
If thats the case, and you do have a two usb connection cable for that drive, you could maybe connect one to another power source (computer usb, wall adapter, etc).
Don't know if any of that will actually work, but the theory sounds good in my head.

I have an external hard drive also but my Note 2 doesn't recognize it as a memory drive. It's powered by an ac adaptor so I dont see why it won't establish a connection.

You can get a USB hub, and do some modification on it.
When I was using my nexus s, I do this:

Just Solider + & - input in your usb hub (input), power your external hard drive with your power bank... So it won't suck your battery

I have mounted a 128Gig USB drive. No Problems! I will try to mount my 2Tb drive to my note via a Volcano external drive unit.

Same issue for me. It says blank memory device. I have a thermaltake 2 bay drive that is powered. I guess that it has to supply its own buss voltage. So much for the 2TB drive mounting.

Or you can get a powered USB Hub. So that the hub powers the HD and not your phone.

Also pnce you get it powered up you might need to format it. I am unsure if this phone can read ntsf. Everything of mine is formatted to fat32 and exfat. So if you get it powered and it shows no memory or something it might be the format.

I do it all the time at work. A small usb hub that plugs into the wall for power will keep your phone from draining so fast.

I solved this issue by using Paragon exfat ntfs hfs from playstore.

The solution that comes to my mind is to just connect both devices to a computer, laptop, or netbook, open 2 windows and drag n drop.
But that powered hub does look like something fun to play with.

I tested it with an xbox 360 controller and it worked fine! The battery drain with it is ridiculous though!

I have two different OTG USB cables, with one it works fine with my ps3 controller, no reaction with the other cable. The one which works is a very short one, the not working cable is very long. But I don't thing the length is the reason.

i've got a feeling not all OTG cables work, i bought a generic one from amazon and when i try connecting a usb memory stick it says it has too much devices connected and i need to disconnect one for it to work. Has anyone bought one recently and it has worked, if so please provide a link if possible. thank you

It arrived yesterday and I plugged the PS3 controller into the phone and it recognised it straight away.
I don''t know if it works with USB Drives or not, I don't have any to test, but it worked fine for what I needed it for, and cheap too.

Thanks mate, I'll give that a go

Just tried the USB OTG clip that i used on my HTC One and it doesn't show up a simple memory card? Which is weird as it's still working on other devices.
Would be good to find out what the problem is, is it a missing pin ? Or just the grade of the kit, plus certain USB OTG cables / clips are working for certain things and not for others, so PS3 will connect but memory won't mount on some, some nothing works on and others everything works, would be an idea to get some clarity on what cables do everything.
I'll test a few more when i get home, just confused as to why this one i've got doesn't work.

Blu r1 hd - OTG not detected even after rooting

Hi,
I just rooted my blu r1 hd and confirmed it by opening my #supersu app. I have root access. But I still am unable to make my phone detect my otg usb. I tried usb otg helper - but that doesnt seem to help. I tried stickmount and it doesnt work.
Can someone please help?

Out of Box the R1 doesn't support OTG, there was a report of someone making it work with a powered hub. But BLU states no OTG.

Used other checker
Hi,
Mi used otg checker and it confirms that my rooted device supports otg. It did not say that before rooting. But still my device does not recognize otg.
Please help.

As stated, the R1 does not support OTG. You can try a powered OTG hub, but your not going to get enough power from the USB port alone on the R1.

Hi Kal250,
Thanks for your reply. Please excuse my ignorance. What is a powered otg hub?
Can you please give an amazon link as a product example?
Your help is much appreciated. I understand that you are saying that it may/may not work. But I want to give it a try.

I can't verify that this will work, there was only one user who reported success using an adapter, though I can no longer find the post, anyhow you can give this a try, you will have to supply power with a charger cable, but I make no guarantee as to if it will work. BLUs official statement is no support for OTG. I'm not responsible if you damage your device(s)!!

Holy crap, can confirm.
I first tried using this powered hub, as well as a powered usb otg cord (similar to this one), it read my generic usb stick, as well as a 500gb HD (well, sorta, it saw it but can't read ext4).. Then I tried just the otg cord, powered, and it worked. As long as it was getting external power, it seemed to work just fine.
Bare in mind, it "NEEDS" the powered OTG cord, running it without having a micro usb hooked up to power in and it didn't work at all, at least for me. Though you can run the hub without power, don't know why this is, but it was how it was acting.
Non drive testing:
It also sorta saw my Logitech F310. In that it pops up that it is disconnecting, but never shows up while connected (with gba.emu). A 360 controller did nothing.
Mouse and Keyboard worked just fine.
USB Audio seemed to not work, at least with my crappy Griffin iMic (think it is an apple device, I got it at goodwil). I also tried a Logitech usb speaker (not sure what model). No audio came though, thought the buttons worked (play/stop/volume/skip). All this with "Disable USB audio routing" not on (as well as on, just in case i was misreading it).
I also have a Pinnacle Systems AV to USB2 (old school rca video cables to usb) adapter I "could" check, however I know of no android app that can take that in. I do know it works with linux by default, ala V4L2, but android is a mystery. It does light up, but other then that no idea, looking through dmesg was a bust for me at least. Eh, nitch item anyways, doubt much here would use it.
Can't think of anything else to test at the moment, but I hope this helps you guys out a bit.

Tried the powered OTG cable and was able to mount a USB flash drive. I did not have to root my R1 HD to get this to work. The mounted drive did not show in ES Explorer or in Solid Explorer. But I can go to Settings -> Storage & USB and click on the mounted drive. That puts me in the system file explorer and I can copy files. (Do choose "Show SD Card" in the menu. Otherwise there are not many places to copy to.)
---------- Post added at 11:49 PM ---------- Previous post was at 11:20 PM ----------
Following up: of course you have supply power to the microUSB port of the powered OTG cable. I tried supplying power from an AC adapter and from an external battery both worked.
Another note: to copy files from the USB flash drive to internal SD or external SD, click on the USB Drive (in Settings->Storage & USB) first, select some files. Then, navigate to the place where you want the copy. If you want to copy to the USB drive, then click on the internal or external SD card (in Settings->Storage & USB) and do the same thing.

I bought a Blu R1 specifically to use in a pair of Gear-like VR goggles, as an FPV headset for quadcopter flight. I was hoping to wire (solder) a wireless receiver to a USB UVC stick, run Go FPV (split-screen Cardboard-like vid player), and power all with a 10k mAh power bank battery.
I'm hoping the UVC not working is just a case of a missing driver. Can you (moshiach101) load a webcam app from PlayStore and see if that installs drivers?

OK. I tried it with a USB wall-mount charger, USB-C micro in a brand new power OTG cable, with a Logitech V-U0007 webcam which was shown to work on a PC.
No dice. I conclude the Blu R1 HD does not support UVC via the USB port.
(and the phone is completely useless to me as I have a good phone and Sprint plan for the family already...)

Is there a way to add the UVC driver to the phone?
Is it part of the ROM, kernel?

It should be added by adding an app which needs it.
The UVC setup works with my HTC One M7. Not with the Blu, so I think this is a HW/FW limitation.

Try OTG Patch or similar from playstore

No dice (I just tried). Pretty sure it's an MTK processor, which doesn't do OTG, and probably why it's cheap enough to sell at this pricepoint.

Use a powered hub I have tried and it works for most devices (keyboards, mice, and USB drives), but for other devices such as an arduino, which is what I needed, use USB Host Diagnostics to install a patch.
