Hello, I have searched the forums and have been unable to find an answer to my question either here or through Google.
I am trying to figure out whether or not the HTC Evo 3D has the capability to use the Android Open Accessory that was supposed to be added in 2.3.4. Though, even though the phone supports may contain the libraries, the hardware itself may not support it. If some one could help me determine whether or not the phone is capable of connecting to an Arduino board it would help a lot. This is the one feature that I absolutely need to know it has before I purchase it.
Thank you for your time and I apologize if this has already been answered and I was unable to find it.
Android Arduino Board
The hardware can do it, but since the 3D is android v2.3.3, I don't think the libraries are there yet. Once HTC provides an update to v2.3.4 (or we gain perm root for custom roms), you should be "good to go".
Just FYI - the Arduino board acts as a USB Host since Android phones are normally USB devices. That and the software are all that is needed to talk to the board....
Thank you very much for your help.
I do not know why the USB Host bit slipped my mind. After all the board I am using is called Oleg's USB Host Shield. lol

Hello!
I’ve to make an Android high school project and I’ll need to send signals through the USB cable (the interpretation of these will be another project) so be able to send 1 or 0s will be enough I guess…
To get that, I’d need the USB Host mod or the Accessory one?
I was thinking to buy this tablet for testing that has USB Host and 2.3.4 Android version but I’m not completely sure if it will be compatible….
Thank you very much!
Please....
no one?....
sadly, with the cheap 'Chinese knockoff' tablets, there's pretty much no way to know something like that.
I say get an old android phone with at least some dev support off Craigslist or something for your problem. An OG Droid (for example) would have more than enough supports and preexisting hacks for you to be able to program the USB port a little.
Thank you strongly. I supposed that all, but my intentions were to get "send that signals" using an non-customed ROM and a "cheap" Android device (I can't no waste to much money on this)
Read in the specifications USB OTG made me think that will be posible to control USB...
Anyway, would you know the difference between USB Host and Accessory?
Thank you very much!

^that should help explain it.
Thank you, I have read before but the only difference I saw was the power source location....:S
I wanted to reply to this post but can't because I haven't made ten posts.
I've been reading up a bit on the BT thing, and was wondering how reasonable it would be to look into replacing the wireless module.
Even though these modules are made for OEM designs they can be bought from places like mouser. I don't think I would be able to get the datasheet from RFM since they ask to request it, and let you sign a NDA with lots of questions.
Has anybody been looking into this option seriously? I don't really know a lot about the software part of this operation, but wouldn't mind looking into the HW part.
As sidenotes:
* has anybody used the UART port used initially for hacking the device for other purposes such as controlling external hardware, or is this out of the question?
* Any chance the NT would get USB host connection somehow? Is this something that is currently being looked into or just not feasable?
regards
Hi,
* @AdamOutler has been the one using UART as far as i know, so if you have questions about it you should PM him (he's the man)
* I think devs are trying to first get Bluetooth working before USB host, i know in the nook color is possible and im sure they have it in their to-do list but will take sometime. one step at the time. If you want to know about the bluetooth issue they are having then check this thread http://forum.xda-developers.com/showthread.php?t=1554956 and here http://forum.xda-developers.com/showthread.php?t=1553040

Hi Veronica,
The post I refer to is in one of the threads that you link to.
The chip/module in the NT is the WL1270, which (according to the manufacturer), just isn't capable of BT. The WL1271 has that capability, hence the question about desoldering the module in the NT and swapping it with it's sister that has BT capability...
Or I really should have missed something...
Hallo everyone!
First of all - I got myself a smartphone just yesterday for the first time ever, so yes.. I'm even less than a Noob.. you can call me noob^2..
Second: i searched the forum but I did not find a similar topic. Either there is no similar thread yet, or I don't know how to use the Forum search engine properly.. If so, please excuse!
I have a SGS2 i9100 (not G) and android 4.0.3. Not rooted (don't know yet how to so..)
I would like to replace my ipod with the SGS2, but the soundquality is very poor. I would like do connect the phone to an usb DAC (fiio E7 for example), but i read that it is not possible to bypass the internal crap yamaha-DSP. So is there any possibility, hack, or whatever, to send the pure, unprocessed mp3 data to the DAC via USB OTG??
Thank you a LOT!
Not currently possible with the SGS2 & highly unlikely to ever be. Devs who have been asked to have a look at it have all gone 'Nup' because of Samsung's proprietary/closed source drivers & so on. To give you an idea of what devs are up against/why nobody will tackle this, read this post.
Only way it will ever happen is if you code it yourself, or a dev with a lot of time on their hands (there aren't really any of these; the development they do now is done in their spare time & on top of the jobs they have) who actually wants to use this themselves.
Don't ditch your iPod.

Well, that's a pitty!
I read somewhere that android 4.1. (Jelly Bean) supports that USB audio out capability. Is that true, and does that mean, that if I could install jelly bean on the s2, I could use usb audio?
Another, probably stupid, question. Is it possible to install the 'not touchwized' - original - version of android on the s2? Would that make usb audio work, or is it a matter of hardware and drivers??
Thak you for your reply!
Hardware & drivers. Won't work no matter what. Unless a dev makes it work as I said in my previous post.
So right now, no one is trying to make the s2 work..? Would donate if someone succeeds..!
What about the Galaxy nexus phone and about the Galaxy s3? Do these phones support usb audio, even though they are from samsung?
1) No, offering money won't make any difference. There have been threads made in General where people have pledged differing amounts of money; in one thread I offered $20, all up maybe 6-7 people pledged money totaling around $150 to get it working. No devs took up the offer. Seriously, this is something that is very difficult & time consuming to get working, it's not simple like some people seem to think. It just isn't going to happen. Money isn't the issue, the issue is time and/or a desire on the part of a dev to use this feature themselves. No dev so far has had either of those nor a desire to get this working.
The fact it doesn't work on stock roms should tell you something.
2) You're asking in the wrong place, ask in the forums for those phones.

Hey there.
Because I'm not allowed to post in the development part of this forum, I'm just gonna do here.
I am currently trying to build a robot based on the Arduino ADK revision 3. It's working for now, but I wanted to expand it by using the Android Open Accessory Protocol to access the smartphones Wifi and sensor capabilities. The problem I encountered is that the S3 doesn't communicate with my Arduino at all. The Arduino is waiting for a connection even when the smartphone is attached.
It isn't a problem with the Arduino. Other programs to parse usb descriptors are working fine.
Have you any idea what I am doing wrong? Or is it just that the S3 doesn't support accessory development?
If you need any code of my programs just ask.
Thanks
Hey there.

This is still the wrong forum .
Question = Q&A section .
Possible more help from XDA forum Android Development and Hacking .

Trying adding a powered USB hub between the adrino and the S3.

i dont think the power is a problem since the s3 starts recharging when connected. but thanks.
i will also post this on another forum thanks for your help
What i am sayimg is to mount the adrino correctly the motherboard of the s3 needs that extra power just like with usb sticks. But i think it would be worth a shot. They are pretty cheap. Well in my area i can get one for about $15.
Sent from my SCH-R530U using xda premium
thanks for your help. in the meantime i found the problem. i activated wifi debugging a while ago and apparently the accessory mode somehow is based on the adb. so i deactivated the accessory mode for usb too. but now its working just fine.
Hello there this is my first post on xda I came here because you guys are android wizards
So that beïng said, I recently bought a phone again. And I was curious to see if I could use my android device to be recognized by the PC as a HID. Like the usb rubber ducky from hak5(modified teensy that emulates HID) . From what I understand you have to modify the kernel to do this. And after that find a way to communicate with usb (from what I've heard the API doesn't support this or something) I'm always up for a challenge but unfortunaly I only have experience with the API and I shure ass hell don't want to brick my phone. So where does a noob start when modifying the kernel? Or am I being ridiculous and it's way to difficult? I do have experience with c/c++ on windows..
Best regards
Seriously__
