USB OTG and MHL adapter

Hi everyone. Has anybody tried USB OTG to transfer files from pen drive etc. to S2. Also any useful info will be appreciated. I am in search of one. Have heard that nokia ones do not work. Can somebody help me??????????

I have used the ones on ebay and the one on DealExtreme. The phone supports only FAT32 out of the box and you have to connect the thumbdrive to the adapter first before you connect it to the phone.
This is the exact one that I have and it works: http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=260795584422

thanks
Thanks mate, will give it a try.

[Q] Official Samsung OTG MicroUSB to USB adapter

Has anyone tried this genuine samsung cable ? I would like to know if this is a true OTG and not just a microUSB to USB adapter. Also, does it support usb mice and keyboards etc ?
I'm not allowed to post links yet, but it is available on mobilefun already.

I have bought dealextreme.com/p/micro-usb-on-the-go-host-otg-adapter-pair-50774 My 16gb flash works fine, but mouse dont. I tryed 2 mouses. One is simple with usb wire, other is wirreles. But no one worked. When I connect, just nothing happned. Any idea how to make it work?

I bought a no name OTG cable in Hong Kong and it works fine, tried my flash drive, my kensington usb wireless keyboard/mouse combo, and my logitech wireless mouse. all of it works fine! can post pics if necessary.

Pls post that otg cable pics.

I bought the OTG cable. It works like a charm and it cost me 15euros. At least it's got the Samsung logo on it.
I bought a Samsung charger too and guess what. The microusb is moving when insert it in the phone. I have to keep it in place in with my hand to charge it...

If it's the wireless one: It could use a driver that GS2 don't has or it's recognized as a high-power device, in the last case though the phone should print a warning...

USB host cable for $5 on Amazon with Prime (works)

So, this works:
http://www.amazon.com/gp/product/B005FUNYSA/ref=oh_o00_s00_i00_details
However, it doesn't work for everything. A mouse works, but a USB Flash Drive doesn't seem to work, nor does another USB device that does work on the Acer A500 Android tablet I have.
So... Yeah. Just thought you guys would wanna know. I'll look into more devices. I know Honeycomb supported all kinds of USB devices (hub, flash drive, mouse, keyboard) so I'm a little surprised the flash drive didn't work. I'll let you know if I find anything else out. Might just be a driver issue we can work out with custom ROMS. Obviously the communications is working since the mouse works. It could be a power draw issue. I have a USB power meter and the mouse draws 20ma. The flash drive that doesn't work draws 60ma.
-Taylor
UPDATE: Works great with a device we are developing at work (basically a USB hub and FTDI chip combo board if that means anything to ya). It draws about 62ma, so the flash drive issue must not be due to power draw.
UPDATE 2: Rooted users can easily mount flash drives using the app StickMount in the market - its very clean and works well! Thanks to user [esoomenona] for the suggestion.

For who lives outside the USA, buy this with international free shipping: http://www.dealextreme.com/p/usb-fe...a-cable-for-samsung-i9100-galaxy-s2-5cm-67186
The only cons is that can take a while to arrive.

Do you get a cursor if you plug in a mouse?

Thank you I was looking for something like this. Finding the right cable on Amazon is like a needle in a hay stack.

For $5 i'll give it a try. Thanks!

Actually it looks like no. One of the reviews points out its not a USB OTG (On the go) adapter. USB On the go is a USB port that can act either as a device (plug it into your computer) or as a host (plug in a mouse, etc). In order to tell the phone which mode to be in, USB OTG connectors need to have one of the pins hooked up to ground. Unfortunately not all of these adapters do (I have no idea what they're good for if they don't) and it looks like that one doesn't. But someone linked to the one on DealExtreme that might work.

Eh I just found a cheap one that looked ok and said it worked with some Samsung devices. I'm also happy its right angle, as its more pocketable. But glad to help!

Here's a cheaper one.
I would prefer this over a one piece, as I am worried about bending the micro usb port.

Shoot, I paid a little over four bucks for that same one from the same company, on Newegg. I should've looked at Amazon as well. Oh well...

Okay, so I received the cable I stated above, and tried to plug in a microSD card via USB adapter, and it didn't work. After a bit of googling, I've come to think of two options for why it doesn't:
1. The cable doesn't work
2. The OS doesn't seem to mount them automatically. I found an app called StickMount on the Market, but it requires root, and I haven't rooted yet.
Anyone know anything about this?

Well I mentioned in the first post that USB flash drives don't work. A card reader is going to have the same issue, as they're basically the same. I think its related to the phone not having its own microSD card, and so it lacks the drivers to mount storage properly. Which still seems silly to me if the device has USB host support, they should include those things!
Plug in a mouse. If a mouse works, the cable is fine.

I honestly think this is going to be it...because of internal storage it doesn't come with the native ability to detect external storage. I'd imagine that app would allow it or that it'll get pushed out as an update down the road...maybe a MOD will get made too if it takes too long.
Either way, when mine comes *crosses fingers for tomorrow* I'll be rooting and post back the results.

Oh damn, StickMount works! Plug in a USB drive and stickmount will pop up asking to run. Then it mounts the drive and my file browser sees it. Then you unmount the drive before unplugging. Wish it was native but this is pretty damn simple. Thanks for finding it!
I was a bit skeptical since the USB drive doesn't even light up when you first plug it in, but once you run stickmount its all good!
Go ahead and root that thing! Just note rooting will erase the phone, so back up first!

I had a Micro USB to USB female for my Nook Color for UBS host. Tried it. Worked like a charm. It even drew enough to power a hub, the keyboard, and the mouse. I was shocked. Im going to but a splitter and use a MHL out to HDMI for 1080 goodness.
Got mine on Amazon for $1.46. Works well (I just wish it was a cable and not a plug though(.

I'll have to see how this works out, ordered the cable.
I have an externally powered USB hub that I can plug into the USB OTG cable.

This is great, I've been looking for these cables. Thanks!
Edit: Does anyone have any idea if you can use an MHL adapter for HDMI at the same time as one of these? I see that some MHL adapters have charging ports, but I don't know if they support data.

Using MHL through a splitter won't work based on how MHL works. You either get USB or MHL. MHL does not use USB-compatible signaling.

Alright, I typed this with a mouse and it's slow, but cool. Guess it's time to root. See you on the other side.

USB cable "OTG" not working am I doing it wrong?

I got a Micro-USB to USB (female) cable form ebay... from China (I didn't know until I chekced later. I usually have the "UK sellers only" option checked).
Anyway, after an eternity, it arrived today. But, it doesn't work when I plug it in. Nothing happens. My Sandisk Cruzer doesn't light up when I plug it in or anything.
I was on the ninphetamin3 Kernel, and I've tried the Siyah kernel, just in case it's the kernel that was limiting functionality... Apparently it's not because it still doesn't work.
It only cost a couple of quid, but is there something I might be missing that I can check before buying another from the UK?

That is not necessarily an OTG cable... did it SAY it was an OTG cable? If not, it probably isnt. Pin 4 and 5 need to be connected (in the micro usb side) for it trigger OTG functionality. if it is not working it means one of 2 things:
1. You didn't buy and OTG cable, you just bought a cable with the ends you wanted, but without the funtionality
2. Something is broken on your phone... test that cable in another phone with OTG capability (go to a verizon store if you have to)
3. I think i remember seeing you need an app to use some flash drives (keybaords and mice work without any app, i can attest to that from experience)

That's the one I got. It's 5pin, but you're right in that it doesn't say it was OTG.
I don't have another OTG compatible device to test with

I got an OTG cable and I tired loads of different things to get it working.... in the end I rebooted the S3 with a usb drive connected and it worked after that.
I'm on stock rooted LG6

yep, it is just a plug adapter.
You now have 2 choices:
1. cut open the micro USB, and connect pins 5 and six
2. buy one that actually says it is an OTG

I ordered a OTG cable now, but also soldered the one I had and made that into one too., But the OTG one will be ok to pull out in public places, lol.

Charger/USB-C - 3.5mm Adapter

Are there currently any adapters that allow charging while also using a 3.5mm jack?
The Google store has this, but nobody can give me any information on what "Coming Soon" means.
Any ideas?

Moshi has them available for purchase now, but only on their web site and not through google.
Hopefully that means google will have them soon, I really want one to leave in my car but i dont know if i can justify the 45$ price tag.

I was researching for such a solution. In the XDA U11 forum, I saw this and ordered it, https://www.amazon.com/gp/product/B01N0R1F1M/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1. You plug the provided 3.5mm adapter into it. It would be a bad portable solution, but might be good enough for a desk. I will report back on whether it works for the Pixel 2.

Yes please report back. As I understand those adapters need to have a DAC builtin, but if you are using oem dongle then perhaps it can communicate to phone through this adapter

I dont know if you looked at the product, but what he is doing is using the included USB-C to 3.5mm adapter that came with the phone, so that DAC would be there.

Spoke with manufacturer, they said it will work 100%
But I already gave away my P2, I decided to keep P1 for now until 8.1 release at least. I was excited about camera but I prefer P1 images they look better to my eyes

It works completely! I tested a bunch of scenarios and am very happy. Only drawbacks so far are the thing is about half the size of the phone and the pigtail is about four inches.
Here is what works:
Rapid charging with a USB-C charger
Playing back music through the supplied USB-C audio adapter with and without charging attached
USB cable to an iPad (at least it connected and was recognized but I could not access pictures; I had the same issue with the data transfer adapter so I don't think this hub is at fault)
USB cable to a Canon camera
USB memory card reader
It would not read my micro SD card in the hub's slot initially but I got it to work.
Notes:
I did not test using the headset adapter with a wired microphone. I don't know if that is supported and don't have one.
You don't have to change the USB settings to get it to work. It just worked automatically.
The charging port is the one closest to the pigtail. The other port doesn't work for that purpose. The white lettering on silver case is hard to read so it is easy to miss which port is required for charging.
I didn't test it with HDMI because I cannot get the phone to work with the HDMI cable I purchased even when directly connected.
Here is the link again: https://www.amazon.com/gp/product/B01N0R1F1M/
*edit: got the card reader to work.

Hopefully we'll have a portables position under $45!
In the meantime I bought a Bluetooth receiver so in the car I can charge and use BT for audio to the car.
You could also buy a Bluetooth receiver and plug your earhones in it.

So the 4 inch pigtail goes into the phone, the PD charging port is connected to your Pixel wall charger, and the 3.5 USB c adapter connects to the data only USB C port?
Did you try to connect a keyboard, mouse, or USB Ethernet adapter to the USB A side? I am curious if those device work on the Pixel 2.
Thanks for your info.

Correct; that is how I connected it. I tried an AnyKey security key that presents a USB keyboard interface and that worked as a keyboard. I don't have a mouse or ethernet adapter to try. I did also try a USB memory card adapter and that worked too.

I'm using this one, which is the same as the one above but cheaper. https://www.amazon.com/gp/product/B075FHLTNM/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
It will charge the phone rapidly, play audio through the headphone dongle, read a micro SD card, read USB keys through the USB A ports, all at the same time, not bad for $14.

Moshi speaks!
FYI, this is response I got from Moshi rep, regarding the charge/play adapter.
While we do not know when exactly it will be available in Google's store, the same product is already available in our own web store - https://www.moshi.com/usb-c-digital-audio-adapter-with-charging
We are aware of that some users have been experiencing issues with this adapter, and we are already working together with Google on a solution for this. With that said, it appears that this only affects certain Pixel devices, as a clear majority of users (including our own product team and Google) haven't had any issues when testing multiple adapters on the Pixel devices in our office.
Although our team does not have a solution for the reported issues at this time, they are currently working with different software updates to see if this may resolve the issue. We are therefore not working on any hardware upgrades at the moment.
Hope this information helps.

Same here. I would love to find anything that will let me listen to my music with my wired headphones and charge my pixel 2xl at the same time. Google created this situation for us when they removed the jack. You would think they would at least have one solution. So if you could send me a new link or post it here, that'd be great!
