Just reading through this and came across where he says "The patches are quite device-independent, so they should also work for other similar handsets, like all SGS variants (Captivate, Vibrant, epic, etc.), and also some distant relatives like the Nexus S, or the Galaxy Tab."
Well, I would label our devices as a "sgs variant" or at least a "distant relative". I have always thought it would be nice to have OTG, just wondering if this would be possible to port into the kernals for the for the galaxy players. I will look into it, and hope some of you could to.
This shouldn't be in Development - either General or Q&A (Development should only be for something you've created or are involved in creating).
That said - the OTG port is so limited that I question whether it's really worth it as anything but proof of concept - Needs an external 5V power supply, lots of enumeration restrictions, etc.

Sorry about that.
maybe work different rom.

Hey,
I purchased a USB OTG cable for my Archos G9 I'm getting for Christmas (two days!)
I tried a mouse, 4 flash drives and a keyboard, knowing that the Ace most likely doesn't include Host mode.. It didn't work at all, So I was wondering if any kernels support it or roms?
I know it can be hacked through like kernel modules, Just wondering how much work it would be to create modules and drivers for it? I'm not that experienced with creating kernel modules and what not, I've created and ported roms and fixed kernels before for the GT540 and to be honest, I'm really not that good at it haha.
Does anyone know anything we could do to make it work?
Thanks in advance,
Jamie.
-Edit:
Just saw this for the Blade, Based on the 600mhz 7227, http://sven.killig.de/android/Blade/usb_host/
Maybe this could be edited for our Ace?
I think that we can have USB Host, but i don't know why nobody tried to give us that feature... maybe cpu arch?
However, i want it too

It would be pretty cool Probably drain the battery alot though haha.
Its supported by the CPU as Qualcomm have said before, so its up to Samsung or a pretty cool and nice dev All the drivers and Kernel Modules are on the page I linked to so it'd be a case of making it all relative to the Ace and its kernel
Swyped from my GT-S5830 using XDA App
Hope I'm not bringing up too old a thread, but I searched in correct forum and this is what came up.
Any news of anyone building the correct Kernel for the Ace II in order to support USB Host ?
II have a Samsung engineer getting back to me about if Ace II Android 4.1.2 can mount external USB devices, but unless Samsung supports this II'll have to replace Android with something that can.
Needing this for photo transfer from camera SD card. I could use a mini SD card but just paid out for a highest speed SDHC card. Anyway those llittle SD mini SD cards are too easy to lose on mountaintops and that kind of thing
USB host wiht libusb
I also am still looking for usb host mode support.
Does anyone have any information?
Hey everyone.
On the German Samsung site i found this adapter for the Galaxy SII:
http://samsung.de/de/Privatkunden/Mobil/Mobiltelefone/Zubehoer/etr205u/ET-R205UBEGSTD/accdetail.aspx
It allows the SII to be a USB Host. Does something like this also exist for the Evo 3d?

Like the above post said...you'll need Rom+Kernel support enabled...as of right now the kernel is only working on some evo3D's but not all. Chad has stated his next sense kernel should have it working on all evo3d's that have Rom support. At this time I think the only Rom confirmed working with Host mode is Olympus. I'm running Chad's Kernel & Olympus but still haven't got it to work. I'm just waiting for Chad to finish up his release, can't wait !!
BTW search Ebay for USB OTG or OTG Cable you'll see plenty
Sorry for my English .. Hello everyone first of all, any driver to control the MHL from the PC?
The truth did not know very well where to place this post, but I think the media is the main function and see if you're lucky, the idea is to propose or if anyone knows, the android can control from your PC, as the case Samsung TVs that recognize the application MHL Device Anynet + (post link). The idea is to connect mobile phone to a computer with a touch screen and control it from the screen contenplando the quality of this type of connection and future applications, CarPC, game systems, internet browsers.
So far the closest I've seen is through a remote program or Android QtADB Commander, but they perform a virtualization and graphics functions are very limited (videos, photos, games, etc. ..).
An interesting idea would be that an application for Android was able to control the touch screen driver THROUGH USB host our phones, this topic is more interesting and juicy indeed already been mentioned in some places but unfortunately I guess we have to wait to get the ICS to Partin, do not you think?.
For those interested in the latter is here.
Greetings.

I am still posting here as, although the device i have is 4 androids ( EVO, EVO 3D, TRANSFORMER PRIME, ARCHOS A10|1T:8000), all with HDMI port (except the 3d, which has HDMI output through the USB port with a converter thingy), what I am posting about should, i would think, be an android-wide thing, not anything specific, especially for ICS and jellybean.
I know, and have read, all the specific device threads about HDMI input, but, as it would be near impossible to unit-specific code for HDMI communications, and as the HDMI standards state that they are functionally,and always have been, that HDMI is a 2-WAY communications protocol, then shouldn't an "HDMI input display" code be able to be written for Android as a whole, so there could be a stand-alone app for any android with an HDMI port to just 'sleep' android when an HDMI is connected with video-out signal being transmitted over it, and just default to a display?
Especially with ICS able to handle not only HDMI 2-way communication, but its' support for full HD displays (for example, TransformerPrime T701, and GoogleTVs), or even whatever the display is capable of?
So, shouldn't the app just be to read the port's input, if its HDMI signal, it can either 'suspend' or 'sleep' android and allow the device connected to simply pass display signal to the device?
If HDMI follows standards, which it must in order to even use the HDMI trademark, then any android which can dispay to HDMI out, by definition, MUST be able to receive HDMI communication from the other device. Anything over HDMIversion 1.5.
I have a working familiarity with HDMI output, but unfortunately, i've never had a chance to work with HDMI input coding, so I understand I could be way off.
so please, just tell me if I am mistaken, i can and will delete this thread or move it where you guys suggest, just please don't ban me for thinking this all the way through.
But my understanding of Android and HDMI is that anything that is capable of transmitting HDMI can be read by anything else that has HDMI (except china with its strick firewall) therefore, anything with an HDMI out and an HDMI to HDMI Mini or Micro cable should be able to connect to DVD players, computer graphic cards, XBOX. etc.
Why?
just to use as a display. I'm not sure about the archos, but i know the evo3D dual core and the ASUS ee transformer prime should have enough power to use as displays, probably with suspend, ANY HDMI signal and decode it and display it just as if were live. People would use to plug in dvd players, video game systems, etc while on the go.
So, with 2-way communication through HDMI, shouldn't we be able to make an app that would turn the android device into a small portable screen?
-----
Once again, i am thinking this is is an android-wide app or mod, which is why i am posting here. Please someone just tell me if it needs to be moved and not ban me for posting here, like the warning is saying.
I had snippets of various code pasted here that should be able to be pieced together into something working, but, as I don't really know what the lines mean or how to code it together, i'm gonna just end this here and see what everyone says.

Does GoogleTV handle the TV's various inputs through Android processing? could we just extract the control lines and turn it into an APP from that? or does GoogleTV only run when the TV is on a specific input channel, no android runs if switch input to Component or HDMI or others than the 'dedicated' android input selection?
No. There is not a way to use an output as an input. Period.

Dear XDA people,
I have not found any conclusive topic on whether it's possible (or is already done) to enable USB audio output (to a DAC obviously) on the SGS2. Some shreds of relevant topics have crossed my path, but they all either died out or were for different models.
So: What is the status? What's the roadblock? Is there in fact already a rom/kernel which has this enabled?
Thanks
edit: There's a feature request on the Android project page, but I can't link to it due to <10 posts. The title is: Issue 24614: Enable USB audio on the Galaxy Nexus (or any Android 4.0 device)
Not currently possible & unlikely to be on the SGS2 tbh. Devs who have been asked to have a look at it have gone 'nup' & don't have the time/inclination to work on it (blame Samsung).
Only chance of it happening would be to code it yourself or for a dev who actually wants to use that functionality themselves to have a go at it. People have started threads on here where people have pledged X amount of $ if a dev can get this working, but these threads fall off the radar due to lack of interest fairly quickly & there have been no takers on the dev side.
I wouldn't hold your breath.
Right, that's sad to hear. No developers who want this? Strange... thought they'd be interested in getting the best possible out of the hardware available.
Guess I'll wait for future models then. Thanks for the clarification.
From the comments I've seen from the devs who have been asked, it's a case of not having to mess around with/spend a lot of time dealing with Samsung's ****ty closed source drivers etc. Take CM9 as an example, those guys have been doing that since the first ICS leaks were released late last yr & frankly I don't blame them for being fed up.
Most people don't realise exactly how much work goes into making things work on a custom rom (a real one; not a winzip job like 80% of 'roms' on here), getting this to work would not be a walk in the park.
And the other thing is many (most) people also have a dedicated media player which puts out much better sound than the SGS2 anyways.

Yeah don't get me wrong -- I appreciate the work that goes into messing with this stuff (especially the process of discovering how it actually works, the reverse engineering of sorts). I just thought that this was a pretty big feature to have and was surprised there was so little to find about it.
And yeah, I also have a better media player (Cowon D2), but the integration into a single device is the attractive part obviously, and unfortunately the SGS2 doesn't have the good audio chip that the SGS1 does have (Stupid Samsung).
Yep using the Yamaha chip in the SGS2 was a puzzling move given how universally praised the sound quality was on the SGS, and made even more puzzling by Samsung going back to a Wolfson chip on the SGS3. A moment of madness perhaps. Every review of the SGS3 I've read so far has said the sound quality is very good.

And that is exactly the reason why this feature should be enabled
There are quite a few people who enjoy high quality portable audio. Many of them use portable headphone amplifiers as standard headphone outputs on devices are quite often unable to properly drive high(er) end headphones. Many of these portable headphone amplifiers also have an USB DAC on board for use with a computer.
Being able to use USB Audio out on your phone would mean one less device to lug around. The quality of the Android devices audio components would no longer matter, as the external DAC/Amplifier would take over their function.
Just imagine, no more worries about what DAC is put in a phone, as you would be free to choose your own external DAC.
Galaxy S3 can do it, some tablets can do it, so hopefully someone will be inspired to make this happen on the S2 and other devices.
I hear the arguments & agree with you (I personally would use it), but it's very unlikely to happen for the SGS2. Samsung have made it very very difficult to do by way of the Yamaha sound chip & their ****ty closed source drivers/firmware, and devs who have been asked so far have looked at it & gone 'Nup'.
So, as I said in my post above, unless you find a dev with a fair bit of time on their hands who actually wants to use this themselves, it probably won't happen.
Edit - @Coop: Have a look at this post by Entropy in the CM9 thread re: proprietary code/the crap devs have to deal with. Just to give you a bit of background as to why the devs who have been asked to date have all said no.

Hello XDA-forum users,
I've been a fan of this forum and followed alot of guides etc.. Rooted and flashes my HTC Wildfire Buzz (A3333) to CM. Now I'm a persistent aircrack-ng user on linux platform and I know it's possible to get custom made drivers from a blog somewhere on working for some Broadcast chipsets. My phone has a Qualcomm MSM7225 / ARM1136EJ-S chipset and thus not compatible.
I've been thinking to get an external USB adapter to get monitor anyway. Now before buying it, I wanted to hear you guys out to ask if my phone will recognize it as a genuine adapter without installing any further drivers.. Also would the phone have enough battery output to supply both the phone and adapter. Last, I wanted to ask some of you that already own one to give me some tips on the "better" external usb adapters, which ones do I pick?
Thanks in advance
