extusb changes? - Touch HD Accessories

I have a 3 in 1 adaptor in my car, charging, outputting audio and inputting voice.
This setup worked fine on my Kaiser. With the HD I plug it in and get a "Headset not supported error message". The audio will also not output through the extusb, and will only come out the 3.5mm jack at the top I believe.
So what makes mine different to the below? I can only guess that the pinouts differ for some reason? Has anyone seen a pinout diagram for the HD that I can compare with the Kaiser?

Pinout will not help. HTC simply is not using the audio pins of the ExtUSB on HD.
Any (eBay) vendor you see claiming their ExtUSB-[fill in your audio device] is compatible with HD is not well informed. (or does not want to be well informed)

It was indeed eBay, ive just realised I didnt actually supply the link when I referred to "the below", so well done on filling in the gaps!
Thats a pain in the arse. So the 3.5mm jack at the top can accept incoming voice (from the mic), as well as output audio? In which case I can't see a way of making any kind of car kit work for the HD...

i use a normal audio jack out into my car stereo audio inputs, i get calls/audio/satnav instructions etc through the car speakers (obviously have the stereo on aux so dont get the radio at the same time
the inbuilt mic seems to be adequate for both calls and voice command
if not and you are ok at soldering tiny wires etc, then you could do what i did with my old charmer......
i took the wired headset, cracked open the mic/button press> attached a 1/4" audio socket to the headfone terminals on the PCB and a car mic (£3 if you shop around) to the mic PCB terminals. tucked all the wires away behind trim etc and had a custom built integrated hands free car kit (at the time i didnt have audio in on car stereo so adapted some el cheapo "ipod" speakers as well)

2.5mm Headset

Does anyone know if one can use any 2.5mm earplug handsfree with the XDA Mini S? The one supplied is difficult to carry lots of wires, would like to have a monaural one. Has anyone tried any? Kindly let me know. Thanks.
I have been looking for the same earphone since i bought the item on JAN06, till now I still cant find a compatible one.
That will be helpful if anyone know which is the best headphone with microphone.Not the Bluetooth one!
Thanks!
ebay Adapter eventually works
Hi there,
I was also looking for a good headset fromt he beginning on, the issue might be solved if I can install the A2DP software (will try later), but a nice wired headset would still be nice.
My favorite would be the ones SonyEricsson is shipping with the music phones.
I actually tested a 2.5mm adapter with cord and speakerpice (with clip) plus adapter for 3,5mm, which would be perfect. One was for Nokia, one for Motorola - both are NOT compatible with the HTCs!
Lately I saw a shop selling the same adapter specifically for HTC devices, so the problem might be solved.
Also I saw 2 wired 2,5mm stereo headsets from Jabra on the US website, they are for sale there but NOT in Europe. If these would work, they would for sure be of very good quality.
Anyone tested these?
Found one
I found one listed on Ebay under HTC Wizard. Its item number 9716253639, seller's name is 5starcommunication. Looks quite cool and they will mail it world wide. Will take sometime before it reaches India. But if anyone in the US orders and tries do let us know. Thanks.

I bought a 2.5mm to 3.5mm adapter from Expansys UK and it works just fine. Sorry - no part number on me, but it should be easy to find on their web site.
Hope this helps

I use it for headphones only (senheiser PX200 which sound great with the Wizard!), so not sure if they have mic connected or not. Sorry.
Get the adapter at radioshack.. there r tons n tons of them for $3.. i got one n it works like charm..
with/out mic
I wonder if the ones from Radioshack have a mic in the wire?
I have an adapter 2,5 to 3,5mm with GREAT sound quality, however without microphone in the adapter, thus I always need to unplug the adapter and take off the headphones to answer a call - sucks!
As mentioned so far i Only saw one adapter on ebay WITH a microphone in the adapter piece (and clip on the back) - but do not know how it performs...

2.5 mm to 3.5 mm adapters at Radio Shack
Beware of the Radio Shack adapters. They stick out and are easy to catch on a doorway as you walk through it. I did so a few weeks ago and the headphone jack no longer worked. The adapter male end bent back and damaged the phone female socket. The result was very quiet sound from the headphone jack, totally unusable for phone or music.
I sent the phone back to T-Mobile and they very kindly sent me a replacement. I bought a new Radio Shack 2.5mm male to 3.5 mm female adapter and the same day proceeded to catch it on another doorway, bending back the male plug, and damaging the phone female headphone jack. No sound again from the headphone jack. I will stay away from the headphone adapters from now on.
Phone speaker not working after using headphones - No sound
I had a similar problem (not the same). After using a 2.5 to 3.5 mm adapter my phone speakers and the mic didn't work anymore. I was about to send the device in, when I read about a solution (I think it was in XDA-Dev somewhere).
You'll have to gently move the headphone jack forward and back, twisting it a litte or even better use some compressed air blowing into the jack. It works best, if you to take out the battery and blow from the back.
My speakers work again, but the same thing happens now and then. It seems there is some switch inside the headphone/mic jack, which doesn't go back. That only happens when I use the adapter.
I realize that this is an old thread, but here is an idea for you. As far as I know, pretty much any 2.5mm headset should work. I don't use it for my phone personally, but I recently purchased a Plantronics Gamecon X20 headset for my Xbox 360 after my old one broke. Since it has a plain 2.5mm jack on the end, I thought I would plug it into my phone to see how well it worked. The answer, pretty well apparently. My wife said that it was really clear and, likewise, she sounded really clear on my end. It's going to be a little larger than the ones that have the mic hanging down inline with the wire, but on the other hand, since it's a boom mic the sound quality should be superior with less noise. I haven't tried it for listening to music so I can't vouch for the quality there, but since you are wanting a monaural headset I rather doubt that is relevant anyways. The headset was only $20 at GameStop and they had a used one for $10.

In your case, I would say that sounds like a bad adapter. I routinely use one in mine and don't have that problem. It's one of those nasty stick adapters though, so you have to be careful with them. I've seen some cable type adapters for not too much so you might look into one of those instead.
Found info which might help
HERE IS AN/THE ANSWER.
My WIZA200 and Sony P900 phone the mic headsets are compatable, even the answer button works. If you cant find what your looking for under the flavour WIZa or HTC etc... just look for what you need as a P900 type and you will be sorted.
I just checked the pinouts and this answers the very much asked question... what are the pinouts.... here they are....
http://pinouts.ru/CellularPhones-P-W/sonyericssson_headset_pinout.shtml
FOR WIZA AND SONY P900 >>>> 2.5mm 4 pole jack: PIN1 LEFT+, PIN2 RIGHT+, PIN3 MIC+, SHIELD(PIN4) GROUND. I just checked with multimeter and to get call answer pin3 mic and shield must short to signal the press of the answer button.
---
Just for reference Nokia 2.5mm 4pole jack is very odd... this is how they do it.
http://pinouts.ru/CellularPhones-Nokia/nokia_headset_pinout.shtml
on 4pole 2.5mm: 1=speaker+(positive) ### 2=mic+ ### 3=speaker -(negative) ### pin4 = mic - ###short mic+ and mic - to answer call
on 3pole 2.5mm: 1=speaker+(positive) 2=mic+ 3=shield(ground-negative) ### to answer call short speaker and shield.
See how they change their minds... first on 4 pole jacks answer call was on mic side short, then it goes on 3 pole jacks to short the speaker and ground to answer call... can these guys not make up their minds. Grrrr... totally baffling logic in this design, escept they can keep you buying specialised gear for each phone
Glad to see Sony and HTC used a more logical system and seem to stick to it. I suspect the HTC Touch HD 3.5mm is wired the same as the Wiza 2.5mm system just 3.5mm jack not 2.5mm jack.
Someone should make a 2.5mm 4pole to 3.5mm 4 pole converter to use old cherised headsets on the HTC Touch HD... know of any, anyone?

Another solution.....
I know this might sound odd but a simple solution is get your stereo headset & mic thing and cut the right earpiece lead off...
Now you may have to strip the wire a bit and wrap a piece of insulating tape to stop the wires inside touching, which will cause problems (crackling or loss of audio on remaining speaker most likely). Once the wires are safely insulated away, youll have what you are seeking, a monaural one earpiece mic heaset... saves having to buy one that your finding hard to do.
Seems a shame to sacrifice a stereo headset down to mono, but if thats your poison, go for it.
pinouts.ru is the shiz
Get out the soldering iron and make a frankenstien. I grafted a 3.5 female to my old nokia's pop port so I could hook it to my stereo (before I got a BT adapter) and to my amplified helmet speakers (that were sorced from a computer speaker set.) Before I lost the phone I was planning to add a 2.5 mono female socket for a lil clip-on mic I have. Point being, it's only 3 signals and a ground, should be able to come up with something.
ts worth having a go
Yeah having a go is definately worth it. I just utilised the pinouts.ru stuff and a bit of personal common sense knowledge of the wirings and managed to make myself a 3.5 touch hd 4 pole jack into a 3.5 3 pole jack which works ofr my aircraft. I can now fly and make calls through my pilots headset. It shows it can work. You arent dealing with any dangerous voltages... its all piddly "put it on your tongue and you wont get hurt" voltages... speakers and mics... all easy to work out. Worth having a go.

9100 2.5 audio pin out

whether I am "search" disabled or there is no info about audio 2.5 jack pin outs.
will somebody give a link or provide connection diagram for mic, answer/mute button and audio outputs?
my aim is to make my own cable to connect the pda to car stereo to listen mp3s and also place a remote mic and switch somewhere in the car.
its done!
thanks a lot to whom gave me info about this topic. Here is what I have done today;
I bought an after market 2,5mm stereo headphones with mic and switch. it was 5 YTL equvalent around $3,5. I had the chance to try it with my qtek9100, but there was very poor sound level and quality, I didnt even try the mic. Actually I bought it just to get one 2.5mm 4 conductor jack.
I tried to make a drawing how the connections were, marked as "before". It is so wierd wiring that I have no idea which kind of device uses this kind of connection.
After modification, as you will see, instead of soldering the existing ear pieces, I soldered a female 3,5mm jack, so that I can connect whether a stereo headphones to use it as hands free or a casette adapter to use with car stereo and listen to mp3s(which in this case, when I receive or make a call, it will mute the music and give other sides voice to car speakers). Ive tested both possibilities and it works quite fine.
I hope this helps to ones that are willing to make this kind of adapter themselves.

AFAIK pin 4 - left channel, 3 - right. So U have reversed stereo sound or wrong picture female connector.

Modifying head phones to get in-car DAB

I'm considering removing the ear-pieces from my Lobster headphones, and fitting a 3.5mm stereo line socket like this one: http://www.maplin.co.uk/Module.aspx?ModuleNo=1210&criteria=3.5mm stereo socket&doy=24m5 to the end which would connect to one of these http://www.coolsmartphone.com/index.php?option=articles&task=viewarticle&artid=421&Itemid=3 FM transmitters to get DAB radio in my car.
The reason for modifying the headphones would be to retain the antenna function of the headphone lead, which would be strategically placed in the car to hopfully pick up a decent signal.
What do you think?
Get yourself a jack converter
I've been thinking about doing this too. I've got a small (Lobby size) 2.5 mm jack to normal (iPod size) 3.5 jack stereo convertor from e-Bay. I use this all the time as I don't like talking 2 sets of ear phones around with me.
http://cgi.ebay.co.uk/2-5mm-to-3-5m...4QQihZ011QQcategoryZ14419QQrdZ1QQcmdZViewItem
Presumably you can get a wire (normal jack female to normal jack male) instead of detroying your headsets!
I wasn't sure whether an alternative cable would work as an antenna for the DAB radio channels like the original head-set does.
I have two headsets, so doesn't really matter if I butcher one of them.
Can you confirm that when using a 2.5mm to 3.5mm adapter and alternative headphones, the DAB radio stations still work?
Thanks!
I think it is the best one.

iPod Converter
http://www.ipodconverter.com
i was thinking about doing this, but i've heard that these fm transmitters really don't work that well?
From what I've read, just like most other electrical goods, some are good, and some are not.
According to this review http://www.coolsmartphone.com/index.php?option=articles&task=viewarticle&artid=421&Itemid=3 of the Audia X transmitter, the sound quality is "excellent", but I guess sound quality is quite a subjective thing, and what's excellent for one person's set-up may not be for another's.
The Audia X is now available in the UK from places like this http://www.intomusic.co.uk/scripts/digiana-audiax.asp
so anyone got this working?

For the best result you are better off soldering rather than plug in, wherever you can.
I am going to put two phono sockets on mine, to plug into Hi Fi so that I have DAB reception on stereo.

Yeah, thats the plan, remove the ear-pieces from the headphones and solder a 3.5 mm stereo socket on the end so I can plug in the FM transmitter.

I've tried 2 types of headphones with this but the radio and tv function won't work - not enough signal.
So I guess it's back to the original plan of butchering the headphones.
Sorry didn't realise that FM trannie had a male plug on it. thought it would have a female.
Mind you, being a trannie, how can you be sure.
Got it working
I've just got around to giving it a go.
I bought my FM transmitter (Power Trip FM) from HMV, and it comes with both 3.5mm and iPod connections.
I used the stereo 2.5mm male to 3.5mm female converter I bought off eBay.
Plugged it all together and hey presto, TV with the sound coming through the car speakers.
I'm in a good DAB area, so the signal is fine - even better with playing DAB radio.
No chopping or soldering required!!!
ringp3ace, are you saying that you're successfully tuning into a DAB signal using only a 3 pole 2.5mm jack? From Aleemz’s experiments with this earlier in this thread I thought the conclusion was that this wouldn't work. You must be in an area of ridiculously good DAB signal!
kettle,
Yep.
lobster > 2.5mm to 3.5mm > PowerTrip = no problems.
I am in a good DAB area too.

HTC P3350 W100 Wired Remote Control

Does anyone know if the HTC P3350 W100 Wired Remote Control
http://www.expansys.com/htc/p_htc_item.aspx?i=147564[/URL]
will work with the Cingular 8525 (Hermes, TyTN)? This is sold in Europe and can be had in the US from Mobile Planet which seems to be the same as expansys.com.
On the European HTC site there is also a media fix that may apply to this accessory as well as the Y connector.
HTC audio Drivers
Downloading and installing this driver update will provide your HTC mobile device with the latest available optimised software for use with the following accessories:
YC A120 Y-Cable adaptor
The hot music setup for Mogul and 8525
I just purchased the HTC RC W100 Remote from Mobile Planet. It connects to the phone's extUSB and provides a 3.5mm headset jack that carries the mic port out to the connector. It has a 36" cord so there is a lot of cord if you have a long headset cord.
The head has controls for fast forward, pause, +/- volume and you can answer/end calls, mute and put a call on/off hold. This assumes that you have a mic on your headset to talk into.
The http://www.Europe.HTC.Com site says it is for the TyTn II but it seems to work with both the 8525 and the Mogul . . . It is not on the USA site at all.
I use the Sure SE110s stereo headset (individual internal sub-woofer component) and added their MPA-C cable that has a mic in it (Thsi would work for any headset). I have not found any other solutions that wok this well.
The standard headset really has poor quality and is uncomfortable for my ears. Bluetooth is either a mono headset w/ mic or a stereo headset (no mic) and the battery life is unpredictable.
This way I can ride my bike and control my music while the Mogul stays in my camel-back and when a call comes I can actually answer it and then go back to listening.
Very cool setup.
So this doesn't solve the headphone problem? Can't I just buy this and a pair of headphones? I don't need handfree anyway
E: Why a 36'' cord? I totally lost interest

I do not know what headset problem you are referring to but this is definitely a solution if you want to listen to music with a good stereo headset. I just happen to like the Shure stuff because they eliminate some road and wind noise while I am riding my bike or skiing. Also the higher end ones actually have miniature tweeters and sub-woofers built in.
All you need is the W100 and any headset with a 3.5mm jack.
As it turns out, I just found out the unit has a built-in mic and that eliminates the need for a more expensive headset that has a mic. There was nothing in the manual that came with it that talked about the mic! So RTFB does not work!
It also comes with a small disc that has the driver in it. I tried to install it on my Mogul but it said that I had the latest driver . . .
As far as the 36" cord, my Shure headset comes in 2 pieces, the earphones are on a short cord so it is not too long. If you had a standard headset, it might get a little long.
The other side of the Shure headset has the connectors that go into the device(s). This way you can have several different connectors for different phones, MP3 players, etc. Blackberry's and Razor's have different jacks and most cell phones like the HTC 8125 (Cingular) use a 2.5 mm jack.

extUSB adapter that supports headsets with microphone?

I posted a reply to this thread: http://forum.xda-developers.com/showthread.php?t=450197 because it also talks about such an adapter, but I thought I would post a new thread for the phone that I actually have.
I'm looking for a extUSB to 3.5mm adapter, but not the common kind that allows you to plug in stereo headphones or has a microphone built inside the adapter. I'm looking for an adapter that allows you to plug in stereo headsets with in-line microphones. These headsets are designed for iPhones and BlackBerrys and has a 3.5mm connector with an extra ring to support the microphone, and I'm hoping to find an extUSB adapter that supports 3.5mm connectors with three rings so the microphone would work. Does anyone know if such a thing exists? Thanks.
I use this one. It's kind of big but it is the only i can find that I am able to use my iphone headphones with inline mic. After cupcake came out the adapter stopped working but is now working with cyanogen's rom. I would love to find another smaller one that will work with an inline mic.
Thank you so much flowidc for confirming that such a thing actually exists! Please keep me up to date on your quest to find a smaller version of the adapter.

Great adapter and good build quality too (it has rubbery coating on the cable and it doesn't feel/look cheap unlike some adapters with this style). Great for driving headset since it already has built-in mic. You can use any headphones you want, even though I think the original pair that comes with it performs quite well. The downside is that there's no manual volume control on it, but I can live with that.
Dream not of inline microphones...
I got the OEM adapter as well, but on my ADP1, it doesn't fully work;
I can charge, but the 3.5 and 2.5 jacks are dead. They neither work as outputs or inputs. If I plug an EXtUSB to 3.5 adapter into the EXTUSB headset port on the OEM adapter, the phone's microphone is disabled.
I really want an adapter that can be used to connect, via 3.5 wire, to the car stereo, and still be able to use the phone's microphone, or be able to plug in an external microphone for hands-free use.

I have a similar setup, I discovered yesterday on the way home a way to get audio through the 3.5mm jack. This is a convoluted way, but it did work.
1. I had my OEM adapter plugged in
2. I plugged in my OEM headset to the headset jack
3. I plugged in the 3.5mm adapter into the 3.5mm jack
4. Started the music player
The sound came through both the headset and the car radio, unplugged the headset and the sound continued to play through the radio. Once the 3.5mm jack is unplugged, the process will need to be repeated. I hope this helps.
