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.

USB OTG on stock rom issue.

Bought 2 USB OTG cable a few days ago but I've been unable to get it work. The moment I plug it into my HTC One, a "Unable to charge device. Please use the supported charger" error. 2 different USB OTG cables, same error. Bought at different times after I couldnt get the first cable to work.

I'm having the exact same issue... I have 2 cables which both work with my Nexus 7 without any problems what's so ever. Does anyone know if there is an "official" cable from HTC or is there some kind cable standard which has to be adhered to, so it works?

I just got a cheap usb otg cable from eBay, works fine for me. What size drives are you trying to mount?

The Stock Kernel doesnt support NTFS or ExFat... u have to format to FAT32 to get otg to work...
Maybe there will be a kernel with ntfs or exfat support someday...

There can be problem with your pen drive. Cause i had lived the same problem. My sd card works in pc but not in phone. I tried using my mouse or another disc with OTG cable and they worked.

The stock HTC kernel has a whitelist that module blocks OTG access when a certain limit is reached like required voltage by the accessory in order to work. Custom kernel now has this disabled so you might want to check that if you want. But if you prefer stock kernel I suggest you guys look for low powered USB drives instead. Cable alone won't have any issues at all with compatibility.
The main issues are the filesystem type & the electrical current required by the USB drive or any device you want to use for OTG.
The charger notification is a bug and might get fixed soon by HTC but it won't have any effects on OTG itself. It's just the kernel mistakenly identify the OTG device as a charging mechanism.

one from amazon, and 2 from ebay, worked great on my HTC ONE S... and samsung galaxy s3, on my HTC ONE, the freeze up, lock up, i dont even try it anymore.
yeh, i also get the charging thing error...
i believe the one i bought also said for google nexus... i use 32gb...

How does that 4gb stick work is that like a usb flash drive you can use with the One?

Ok, so what about charging phone while connecting something by otg? Is it works on non-stock kernels?

Without any usb thumbdrives attached to the otg cable, the moment I connect the otg to my One, the error pops up. Later connecting the thumb drive to the cable does nothing. Es file explorer does not detect nor does mount usb drive light up (remains greyed out).
Tried connecting the usb drive first and then connecting both to my phone and does detect either. So yeah, I guess might have to buy another usb drive ?

i had the same problem, but....
I was very dissapointed because my htc one could not find the otg usb! I started deleting almost all downloaded software from my device and cleared cash! Then restarted my phone and... Voila! It works! To be honest, i didn't find out the problem, but it works!

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.

It has bluetooth... so in theory that could be a simple alternative... we just need to figure out how to access hidden menus.

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.

Looks like its already been rooted. With what looks like a dual usb otg. They don't go deep into what specific cable but, I would guess it is a generic dual usb one off ebay, or amazon, heres a quick one i pulled from amazon http://www.amazon.com/Micro-Cable-P...8&qid=1375052489&sr=8-3&keywords=Dual+Usb+otg
But if you read into it, they say you can root, but unless your a developer you probably wont get any benefit of rooting....yet, if at all.

Please correct me if Im wrong, but the cable you linked only charges the thumbdrive/keyboard/mice/etc NOT the Chromecast so how would one root it since it does need power from usb plug? I've been searching for correct cable and cant find it; link to correct cable would be greatly appreciated!!!

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 Audio (car usb connector)

I've been searching for a while to solve this.
I'd like to connect my HTC one to my car usb connector.
I've seen several repoirts claiming usb audio works, connecting dac's etcetra.
I know I can connect usb drives with a micro-usb to usb connector, tried it and this works.
But I have also seen people saying you need an USB OTG cable for this, so what is it?
I've already connected my One via the micros-usb to usb cable to my car but I do net get audio via the usb on my car equipment.
So again the question, is audio out available on the htc one (and on other android phones) with the stock rom.
Some of the report where talking about CM roms, I do use the elegancia one but I have no intent of switching to CM.

since the HTC One does not automaticly plug as mass storage i guess that the car radio simply does not recognize the phone as a mass storage with music.. an USB OTG cable would "fix" it since it will force the phone to be shown as mass storage.. (its a guessing anyway)

And you have guessed correctly. The USB otg cable works fine.....except it added ringtones et al when you select root folder. Worked ok if I navigated to the music folder (assuming your vehicle has that option).

Well, for me it does not work.
As I said before I can attach a USB drive to my phone and I can accomplish this by using a micro-usb to usb adapter.
When attaching the drive my phone complains it cannot charge and that I need the standard charger.
But when using a file explorer I can see (read and write) the contents of my usb drive in the storage/usb folder.
I thought this was enough to decide that the converter was OTG but now I'm not so certain about this anymore.
Is every usb to micro usb an OTG or what are the extra requirements?
Anyway I tried again to connect to my car audio and the message I got on the car was
that he could not charge the phone but the phone was as well not recognized as media input.
Because OTG adapters are very cheap I ordered one which explicitly says it is OTG,
I'll see what happens when I can try that one out but in the meantime all comments are welcome.

Yes, the cable I had explicitly said "OTG".
I only experimented with this for fun, my Elantra also supports built in bluetooth (phone controls are on the steering wheel, mic in the roof) so I mainly put my One in my car kit, launch car mode and away I go.
The OTG cable worked well for me when I tried it though. It did NOT work with my Son's Nexus 4 so these things can be finicky.

V40 USB issue

The problem just started.
What works:
1. Low speed charging
2. Access to OTG memory card
Not Working:
1. Connecting to PC. Unknown USB Device (Device Descriptor Request Failed) The PC has the correct LG driver.
2. Fast Charging
3. Android Auto USB mode. Phone won't negotiate with the car.
I have cleaned the USB port with electronic cleaner and sand paper. It made no difference. The port wasn't dirty to start with. I have not done factory reset since the problem looks more likely to be hardware.
Any suggestion?

So, has this device connected to the mentioned PC before? If so, and nothing has changed (like driver update etc), then, sorry to say, but it absolutely sounds like the usb port is an issue.
Even if out of warranty, I'd plead my case to LG. That shouldn't happen. Has it gotten wet? Is any part loose in there?
good luck

I also have a USB problem, but mine keeps asking what I want to use the USB connection for i.e. charging, power supply, file transfer, photo transfer or MIDI device. And the wireless charging doesn't work either.

I got the same problem, I tried to work around the USB port and it fixed itself. Probably got some dust in the port. Try to tug the cable a bit and reconnect. Or you can try different cable.
