I don't know if there is a way to reduce the noise in the headphones. Supercurio also gave up on this. I don't see an other way to fix this. What is your opinion on this. Do you have any suggestions.

Hi, did you buy the DAC? How can it be connected to the Galaxy S II? Im interested in this solution too!

Love to have some way to make these two sing together.
I've been searching around for answers to this...
From what I can gather, there are some drivers required to allow the FiiO to connect to the USB interface on the SGS2 and accept digital (i2s) out.
However, I think FiiO, Samsung are kicking the ball back and forth on this one...no takers on the development costs to make these guys sing together.
I sent an email to FiiO support today trying to fish some answers out of them about this.
You'd thing the SGS2 market would be attractive to them...like it might be worth their time to make it work.
Perversely, I've also heard that ICS will (magically?) allow USB digital audio host mode to work with external DACs. -I'd reference the XDA link where I read this, but there was nothing more than speculation so not much is missed by failing to post that link, I'm afraid.
I'm feeling a bit impatient and sad... One of the key reasons I bought my Android was to play flac. -However, the DAC implementation is so poor on the SGS2 that it makes that capability a moot point.
Sure would be nice if we had a way out of the woods on this one...that doesn't involve buying a dedicated source like a la Cowon.
There are some links in this post:

If I find anything useful out, I'll report back here. I hope you find success!
Only thing I can think of is mass email requests to FiiO asking if they're planning anything to make the E7 and SGS2 sing together.

[Q] USB Host

Is there any chance to make USB Host for wildfire?

I guess not, as USB-Hosts have a different hardware than simple ports.

I heard somewhere that msm 7227 chip supports that feature. But wildfire has msm 7225 and haven't heard that it supports.
And hardware support along with required kernel is needed I think.

AIR a guy made a circuit and gave the USB-Host to unsupported devices. I may remember wrong.

USB Host again
Hi all,
searching through the forum I found this thread and I very much like to raise the debate again. I am not fully convinced that USB-Host may not work at all on Wildfire.
On the hardware-side: can you completely say that the hardware might not support it at all? Many forum threads (not only on XDA) showed ambiguous signals concerning the chipsets.
On the software-side: The official point is the following:
[I wanted to post a link but was not allowed because I do not have 8posts yet. Type in google: "android developer usb host" and it will lead you to the official page]
So from Android 3.1 and higher USB-Host is supported.
As the development for the ICS (Android 4) mods (CG9 etc.) for wildfire is advancing, I am playing with the idea of trying the beta versions to see whether USB host works.
It would be really helpful to hear the ideas of advanced people on this issue. Can you exclude the hardware-capability? Are the e.g. CM9 mods not made for things like USB-Host?
Currently I unrooted my Wildfire and am trying to get things started for flashing it. So yes, quite a noob.
Thanks a lot and kind regards,
Nebi

Ok, I tried the newest version of CM9 'AOSP Based "Original Development" / Source Built ROMs' by arco68.
Unfortunately my wildfire is not reacting when I put in a usb-stick connected to an adapter USB-A (female) to USB-B (male) adapter.
Am I doing sth wrong? Do I need an USB-hub to power 5volt?
Thanks and kind regards,
Nebi

Ok sorry for writing again. My last post today - promise.
On the hardware-side I found out following:
As I still cannot post any links here:
qualcomm.com/chipsets/snapdragon
You can also click on that site on the link below with more detailed specs.
USB OTG is only supported from Snapdragon Generation 3 on. Wildfire (MSM7225) is Generation 1.
I was also egg-headed and still tried another software, too:
I tried the AOSP Based Derivative MIUI V4 Beta1 bystelios97.
He doesnt reckognize anything.
A last thing: I think that in any case the adapter that I am using is wrong. Instead of using a USB-A to USB-Micro adapter you better need a USB-OTG cable to connect both devices.
Game over I guess?

[Kernel][Both] USB host mode support added (github link)

Hi ya'll,
I've just added USB host mode support for the Galaxy Tabs. ( Can some mod move this post to the Android developer forum and bless me for posting in that forum? I'm happy to answer questions/discuss but I can't post there yet because I just created this account)
[Ugh! because I have less than eight posts I can't include github links - you'll need to linkify yourself... ]
The github site is here:
github.../humcycles/galaxy-tab-modified
Documentation on the changes:
github.../humcycles/galaxy-tab-modified/blob/master/Kernel/Documentation/usb/s3c-otg-host.txt
The changelist you probably want if you are want to cherry-pick into another kernel tree:
github.../humcycles/galaxy-tab-modified/commit/99388abf98f8b8583dcfb31339c8673a9fea62bd
These changes fix a number of bugs in the Samsung host mode software but are probably not well suited for regular end users. I would recommend that developers who are generating Galaxy Tab kernels consider picking up these changes.

Wait it so long
Sent from my GT-P1000 using XDA App

Does P1000 have the right hw, can it provide 5 volts to usb client or we also need a power injector (usb hub)?

It really works? That would be superb news! Thank you very much for investing your time in it. Can`t wait to see it in a kernel on my tab.

Yes. It works for me on a Sprint SPH-P100, but I bet it will work on all 7" tabs (the USB hw seems the same). I look forward to some other dev trying it out and letting me know how it works for them. From looking at the samsung sample code, I bet it will work on most samsung chipset based devices (certainly the S5PC100 based ones).

I bet it will also need power for the 5V USB. In the samsung code they have bits that look like it is turning on the right LDO to have power, but nothing comes out on my SPH-P100. Either the sw init needs more work, or they didn't stuff some part when they built up the units.

Does that mean this hasn't actually been tested on a SGT yet?

I've tested it on a few Sprint 7" SGT's here, but it would be great for another dev to try it in their kernel.

It is a great thing, you deserve so many thanks!...
Now what I need is a kernel with usb host and swap enabled.

Can somebody explain why it is needed? What is it good for?

It allows the Tab to act as the controller for USB devices, rather than the other way around. In practice, it means that you can use things like usb sticks, keyboards, mice and the like which usually require a computer (the host) with the Tab.
Anyone more knowledgeable, feel free to correct me.

for months I wait this,
SGS also waiting it too, Shall you post in their forum?

Sure. And since I haven't seen a mod move this to the right forum yet, I hope ya'll don't mind if I bump up my post count to 10 by replying to this thread. After I have ten posts I can post in their forum.

bumping my post count

This is great!!

lol, don`t get banned over this - it is for a good cause, but one never knows if the Mods that see this see it the same way

Hmm - I just want to be able to discuss this in the right forum. I hope I don't get banned, but I don't really care to much - I made these fixes because I needed host mode for my application. I'm almost there - just need one more post

[Q] Any Modder working on USB Host?

Hi all
I tried to look at the major ROMs out there, reading features over features. I can t see anything talking about the USB Host mode recently nerfed on the Sprint version.
I do apologize if someone already pointed out to some ROM fixing this issue, just please reply and let me know.
If noone did it, do we have any hope that ROM cooks are going to take a look into it?
I posted here because the "Android Development" rules say that is not for Q&A, is this the right place to possibly get attention on this subject?
Thank you very much, your job is highly appreciated!

I posted something like this earlier. I'm hoping for the same too. I can't play my emulators on the screen controls. I think it's at the kernel level so someone would have to make a kernel that works with OTG.

he's getting there! i havent used his stuff in a while, but this will definitely bring me back and eventually all the other devs will incorporate this. id get it a week, 2 weeks tops.

ever tried sixaxis controller? you can hook up multiple sixaxis ps3 controllers and it works great. it blows all my friends minds (even my professor) when they saw

Thank you for the update.
It would be nice if someone fix it. This is a very useful feature and is a shame they nerfed on the latest 2.3.4 version.
However, is good "only" if it really works and doesn t break anythng else in the process.
Actually I am a bit skeptic whether "modding" my SGS2 for the simple reason on every ROM I see out there, there are a bunch of bugs involved. Something is fixed with having something else broken.
USB Host would be amazing, but i can live without and i can say there is no reason to me to mess with the original SGS2 OS because this phone just works great out of the box

[Q]What wireless adapter does the SGH-T989 use? [SOLVED]

What wireless adapter does the SGH-T989 use? I am trying to locate this information so that I can start modding the drivers to allow packet injection and monitor mode. I am fairly new to Android modding, but I am fairly experienced with linux. Could someone answer me on here or PM me? Thanks.

Funny how an honest to goodness development question sits unanswered for so long on a "developers" forum. Well I'm sure you weren't holding your breath waiting for this and already found it, but just in case: looks like a Qualcomm WCN1314 (see APQ8060 in the doc, which appears to be the SoC employed by the T989 SGS2 variant):
https://developer.qualcomm.com/sites/default/files/snapdragon-specs.pdf
Maybe this will turn out to be a real development discussion!

Actually, I just found it yesterday. It is a Broadcom wifi chipset (bcm4330).

So it is! I couldn't find reference to it anywhere, so I finally did what you probably did and installed a terminal emulator to ask linux what it is (still not rooted). As an aside, I couldn't find a spec sheet on the WCN1314 at all.

Google "sgh-t989 wifi chipset"
