Hugely disappointed in the absence of an iPad-like USB plug allowing cameras, drives, etc. to be accessed via the usb port, I thought for a moment and realized something. I know an alright amount when it comes to hardware vs. software questions and know that USB otg is not necessarily a hardware issue...the Motorola Xoom was released with Honeycomb and it supports USB Host. Now that very early versions of Honeycomb have been ported to the Galaxy Tab, theoretically shouldn't that mean it now supports USB Host mode (or at least in the near future)? Any thoughts and comments would be greatly appreciated as I'm aware that there are many others waiting for this awesome capability for their tab!!
With past versions of android already fully supporting USB host, I don't see why they don't other than they want you to buy the version with the largest storage space... Android should in theory already have the support as it is an update to the existing android not a new os completely... I feel mostly its just a dirty marketing scheme... (Note: My Archos 101 has a full sized USB port on it with full functionality...)
Can anyone say if gb or ics or custom rom is ever going to support hid for keyboards/mouse, and hdmi only works if a reboot is done it appears disconnect and hdmi is lost, very annoying.
Could anyone say if these two flakey areas of the lg will be fixed soon ?
I have heard HID drivers are standard for all ICS builds but I can't confirm. Maybe it will be fixed then...
Would it be worth switching to the htc evo 3d is hdmi & hid better on this device than on the opti 3d? I've tried to find out but can't clarify if the Htc definitely support hid I have heard it will connect to some keyboards but im not sure its just on custom roms.
I have bought another hdmi cable encase its this that is making trout so ropey, at least my atria although having many faults could do that well.
Isn't ics at least 6 months away?
Thanks.

For Hid, they may add it in GB, or for sure in ICS. About the HDMI, I have it working 100%, I've bought the original HDMI cable for motorola from handtech, some reported that some of the HDMI cables posted in ebay doesn't work properly.
For evo, I've read that HTC's phones are the same, does not support HID.
Yes I have order a moto hdmi cable in the hope it fixes the issue but I somehow doubt it, the as the cable supplied works intermitently mainly on reboot of the system.
Its not an app blocking it but may be a power supply issue as its as if the signal is just not strong enough to register on the phone.
Must be some genious on here that knows better.

Result with the hdmi at least, its a software bug of course! it is very intermittent just plugging in the cable, but if you put the lg to sleep (no dont shoot it) with the hdmi cable in, and just press the power key to wake it automatically outputs the hdmi !
Must be a fix for that software wise surely. Keyboard still an issue, just gonna have to wait for gb or ics more likely ics as no one yet has confirmed to me that gb supports hid even in the deveopers leaked version.Ohh well.

Hi. I've just recently tried out an app from the market that would let me control emulators and some games with a Wii remote, but it wasn't compatible with my G2x. However, I stumbled upon what is most commonly known as "OTG" cable, but discovered they were worthless for the G2x as of now because 2.3 doesn't have USB hosting.
What I wanted to know is, number one, will the G2x have USB hosting when the official 4.0 update comes out, or is it missing some special hardware needed for that? And number two, is there any risks in just getting a cheap MicroUSB to Female USB cable from a trusted seller? Like, can it damage any internal parts because of different voltages between devices or something like that? Or is the worst thing that can happen is the cable simply not working?
I'd really appreciate an answer on this one, because USB hosting seems to open up a lot of possibilities with our devices.
The short answer as of right now is NO there aren't any common ways to enable USB Host. With that said, can the Tegra2 chip in the G2x support host mode?...yes. Will it require a custom kernel?...yes. So basically your phone needs to be rooted to say the least and a kernel framework to enable and support it. I'm actually looking into this as we speak but it's looking like it'll be a while.
As for the cable... no most generic micro-USB cable won't work as is. The OTG cables have either a 'grounded' 4th pin or a disconnected 4th in some usb host modes. But either way you either need an OTG cable or if you search online you can find several ways to splice and solder back generic USB.
I have been looking for a while, but there doesn't seem to a custom kernel that supports USB Host mode. I already have USB OTG adapter (mini Male to 4 pin USB female) + arduino board etc.. So are there any custom kernels out there?

Nothing had really changed on this front, if you want to use Android as an ardi interface, I'd suggest you grab a cheapo phone that supports it out of the box.

Any update on this? Seems ICS/JB roms are out now... any strides in getting OTG to work? I'm looking to make a G2x into a dedicated TV gamer unit to replace my MK808 and forgot about OTG for my air mouse. I have a Bluetooth mouse to get me by but the airmouse was awesome.
I guess I can look for a Bluetooth airmouse as a last resort.

No OTG happiness for the G2X with any ROM and/or Kernel. There is a board from Sparkfun which provides an interface that enables a non-OTG phone to work like one for interfacing to Arduino, etc.

I decided to buy the GSIII after hearing that Samsung had made a great phone, done a decent job of preventing the carriers from ruining the phone, and had become a top level member of the Linux foundation to boot!
But then I heard about the MHL connector scam - and that is one slimy move. Note that it is not only incompatible with the MHL standard, it is incompatible with other Samsung MHL cables. (If Samsung has issued some sort of clarification or explanation then please let me know.)
If I keep looking for perfection amongst the manufacturers I will never get a new phone, but I certainly don't want to simply turn a blind eye to this obnoxious move. If this is successful for Samsung, I can see them creating a fresh batch of incompatible connectors for every new device they create.
I was disappointed that Apple users never raised a fuss through all those years when Apple kept getting rated as the worst environmental offender in the Consumer Electronics industry, but one of the things that sets Android users apart from Apple users is the lack of blind brand loyalty.
So, is there an informal boycott of Samsung accessories afoot?
I guess I'm suggesting that the XDA community could discourage people from buying any of Samsung's "trick" accessories, including their fake MHL and PDMI connectors. I hope consumers will come to realize that, while Samsung makes great phones, their accessories are not a good choice, and I hope that Samsung will come to realize doing stuff like this isn't worth it.
Obviously, the less money they make from this slimy move the less likely they are to repeat it. The outcome is up to us.
[I'm posting in General forum rather then GSIII because I believe this issue - connectors, standards, and taking action - is of general relevance.]
Get ready for a horde of blind Samsung fanboys to flame you, they are just as bad as Apple fanboys. I actually read about this MHL issue. But at least they released the source code for their international device.
For me, personally, I think MHL adaptor is stupid, its clunky and inconvenient, too many wires involved. A dedicated microHDMI connector solution was better, but manufacturers abandoned it to save money because they have to put in another connector and pay royalty. I like the idea of the royalty free DisplayPort, but there is no micro version of it yet.
I'm probably not getting the SIII unless its price drops a lot since the Nexus is still the best phone software wise.
I'm imagining/wishing 2-3 years from now all phones will have a built in projector, but not sure how they'll keep it small.
An update - still appears that the port is a fake
I did my best to get an answer from the MHL Consortium but they would not respond - even to simple question such explaining how a consumer can distinugish an MHL compliant product. But it is a consortium, not a standards body - it represents member companies, not consumers, so I guess this is to be expected. The media types remain confused too.
I put together a quick website to try to inform consumers about this:
http://www.galaxymhl.com/
I believe that Android users are not the 'sheep' that iPhone users are (as evidenced by XDA itself) and I hope we can influence Samsung on this by encouraging consumers to not buy their 'fake' MHL accessories.
Even if Sammie just stops using the MHL branding with the phone and the accessories it will be a big improvement. As things stand, they are really undermining the standard.
Update!
I have received a complete explanation and have posted it there:
http://www.galaxymhl.com/
I'm pleased that, in the end, the advantages of the 11-pin MHL port on the SGS3 are significant enough to allay the initial suspicions that this was just about selling more accessories.
On the other hand, wow, was it ever a ton of work to get a clear explanation - would have thought they would have wanted to explain this clearly from the beginning. At the very least, I might have thought they would posted a clear explanation to a relevant wikipedia article once all the WTF articles started appearing.
It works for Galaxy W?

Yes, finally I got it. So if I've understood it well, The official MHL adapter works fine to allow you HDTV signal (HDMI) and USB OTG at the same time but... every review I read says that the MHL adapter needs power in its microUSB connector, so has anyone tested if it is possible to get USB OTG in that connector fingers-crossed::fingers-crossed::fingers-crossed??
Thank you very much in advance!

I don't have the actual adapter (was boycotting it) so I can't say anything concrete, but I believe that what you are saying conflicts with the explanation that I received. The Samsung adapter for the Galaxy SIII is supposed to be able to get its power from the phone - no need for power from a separate USB cable. The adapter in question is here:
http://www.amazon.com/Adapter-HDMI-EPL-3FHU-Samsung-Galaxy/dp/B0080CXSOU
Can you give me a link to one of these reviews that says otherwise?

Sure, here for example:
clove.co.uk/samsung-galaxy-s3-mhlhdmi-adaptor
It says:
"Please note: For the MHL cable to work you will need to have it connected to mains power."
So I don't really know what to think...Maybe you can power it using a Hub...
At first when I saw the S3 MHL adapter I though in using this connection scheme:
imageshack.us/photo/my-images/341/mhlotg.png
But I've been told that this is not going to work. I have not tested it yet but maybe its a matter of the USB OTG cable used or one of them should not be OTG, I don't know. But I have not been able to find any website or review that shows both, USB OTG + MHL, wroking at the same time and for me that is suspicious...

Thanks for supplying that link. I will try to contact Clove to see whether perhaps they just added that disclaimer about needing power because past MHL adapters needed it.

I think it needs power in its microUSB female connector, but I wish it doesn't. Nobody has the MHL and the USB OTG to make the test? Maybe the OTG cable should be connected to a USB hub in order to supply power also...I need to test that on my own, but the MHL cable has not arrived yet and Im getting holydays veeeery soon...
The whole mhl thing has put me off getting any adapter.
Does anybody know if the S3 has the capability of connection to a Widi adapter or all the companies developing a medfield platform just to go off and make propritary adapters??
FYI;
Intel claim widi for their phones only

HTC have their own adapter;

If the galaxy S3 supports miracast should it work, maybe it will come with jelly bean...

Wrong section, please read and respect the rules.
For a project me and two fellow students are supposed to do for college I'm looking for a cheap Android phone that supports USB Host mode.
According to the official Android developers guide here: http://developer.android.com/guide/topics/connectivity/usb/host.html from the software side only Android 3.1 or above is required for host mode support but from what I read so far both in this forum and on sites I found trough Google it seems that not nearly every phone running Android 3.1+ actually supports USB host mode.
I read that apparently the Galaxy S2 & S3 do support it (although I also came across a thread that said that for the S2 it doesn't work with certain newer ROM versions) but since this is for a college project (and so our college will probably pay for the phone that we're going to use for our project) we were looking for sthg much cheaper than an S2 & S3.
I guess the "optimum" price range (that I guess our college would pay no problem) would be between 100 $ - 200 $.
It would be nice if the device would support it out of the box but if a phone only supports USB host using a custom ROM it would be fine too as long as both the ROM itself & the USB host functionality are stable and as long as the official Android USB host API is supported.
One phone that would deff be in our optimal price range is the HTC Desire (non-HD) but I read mixed statements about whether it supports USB host mode or not.
If there are no phones supporting USB host in that price range another option would be to flash an Android ROM to my HTC HD2 and to use that for our project then (sine I already orderer a Lumia 920 and as soon as that arrives I won't need the HD2 as my primary phone anymore)
Unfortunately the only thing I found regarding the HTC HD2 and USB host was based on Windows Mobile 6.5 and not Android.
Another thing I couldn't find a real answer to is the maximum current one can draw from a USB host mode capable Android device. I read 100 mA on one site but that information was specific to one particular phone I guess. I'm wondering if this 100 mA limit is valid for all USB host capable Android devices or if that limit depends on the device's hardware (which would make a lot of sense I guess).
If it depends on the device what is the highest current that can be drawn from (some) phones?
I also came across this tool (http://forum.xda-developers.com/showthread.php?t=1493325 that can check if a given Android phone & ROM does support USB host but since I don't have a phone yet but rather have to decide which one to get it doesn't really help me either.
Any help on this topic would be highly appreciated by me and my two fellow students who are working with me on that project.
Thanks a lot for reading

Today I bought a Sony Xperia tipo (because several websites claim that it supports USB OTG / USB Host) but after doing a test using "USB Host Diagnostics" I had to find out that apparently it doesn't support it.
When I connect an USB thumb drive directly to the phone using a USB OTG cable the LED indicator on the thumb drive doesn't even light up so the phone doesn't seem to provide any power to the drive. I then tried to put a powered USB hub in between the phone and the thumb drive but the phone still doesn't detect the thumb drive and the "USB Host Diagnostics" tool still says that only the classes are found but that no devices were detected.
Fortunately the retailer I bought the phone from assured me that I can return it if the USB OTG feature doesn't work.
Or do you have any idea how I could get this phone to support USB OTG?
thx
