Mini-USB to 3.5mm Adapter
 

I have from my old phone a Mini-USB to 3.5mm adapter. When I plug it into the mogul, it dosent do anything. All the sounds still come through over the speaker. Is there any way to tell the phone to route the sound over the USB device at all?

What do you have plugged into the other end of the adapter?

It appears that HTC uses a non-standard configuration for its audio output. See the thread titled "Stereo" in this topic for more discussion:

BTW, I tried something similar - I have a USB-end stereo headset from Motorola. It won't work at all with the Mogul. The one supplied with the Mogul works fine. Same connector, but obviously not the same connections inside.

I think that is exactly what I have. It is a motorola mini-USB to 3.5mm connecter. There has got to be a way to route the audio this way.

It shouldn't be a problem to route the audio that way, you just need a different adapter. I'm told that this one works, but I haven't tried it yet (mine should be here in a few days):

Yeah, thats the thing. I don't want any more adapters. I already have so many, I just want this one to work if possible.

The Semsons adapter works wonderfully. It sits flush with the bottom of the Mogul. I use it with my FM transmitter whenever I have a long car trip.

Ummm....think about it
 

"Yeah, thats the thing. I don't want any more adapters. I already have so many, I just want this one to work if possible."

Its an issue of wiring...it isn't an issue of software or "magic".

This is usually an old school analog wiring job, none of that new fancy digital stuff. The headphone mini-usb will have some randomly different property.
This forces the audio output over the usb cable....

Damn, oh well. Thanks for the help anyway.

i get the feeling more and more that they want us to use bluetooth headsets rather than the wired. afterall wired is sooooo yesterday... (sarcasm)

Its not just an issue of "wiring"... or at least, not the simple sense of it.

There's actually an extra pin that HTC uses for stereo sound that doesn't exist on regular mini-USB ports!

If you look closely at the headset provided with the Mogul / Titan (or any HTC with USB audio), you'll notice that it actually looks different than an average mini-USB plug. Instead of both sides being a slight angle, one side of the HTC plug is a perfect 90 degree squared one. That houses the extra pins used for stereo.

Motorola decided to use some of the pins of a regular USB plug, whereas HTC added new ones.

They are NOT compatible and neither is standard!

could be wrong but im pretty sure thats a little bit off ... the squared corner of the ExTUSB connector is just to prevent you from putting it in normal mini-usb socket ... normal mini-usb connectors usually have 5 pins (sometimes 4) ... the ExtUSB is double sided with the normal 5 pins across the wide side (5vdc+, data-, data+, device presence, and ground) and another 5 that carry audio and the call button signal wire (mic+, another ground, left+, right+, and signal) ... im not sure of the order of the second 5 but i could figure it out with an ohm meter and the adapter i made if anyone is curious ...

that semson thing looks like it would work out well ... i wish i had seen it before i chopped my headset up :) oh well ... i like the custom look ..

Dishe is right that there is no particular standard for USB-connected headphones. So there is no right or wrong answer at that end.

There is a standard, though, for stereo on a TRS connector. The Semsons adapter gets it right - it matches the HTC-style USB connection with a properly wired TRS jack. Of course, that's 3.5mm only. If you want to connect a normal set of headphones using a 2.5mm plug, you're apparently out of luck.

if you want the 2.5mm connection, htc offered an adapter that came with the mogul including the earphones.

i was looking into this for the past couple of days, the motorola headset offered wont work, regardless if you have the adapter that comes with the mogul. the tip has to be used throught a 2.5mm or 3.5mm depending on the adapter youre using.

just my two cents, im still looking for a way where no adapter is needed

And with that, we've come full circle. <g> This whole discussion started, a few days ago in a different thread, with the discovery that the HTC adapter only connected the right audio channel.

Seidio is developing an adaptor for PPC 6800 (mini USB to 2.5 mm female jack), will keep you informed.

also Seidio offers a full line of audio adaptor designed just for PPC 6800.

Seidio

yes he is right about that ... but as far as the square corner with one extra pin thing ..

looks awesome ... much less obtrusive and stiff(dangerous) than semson's product ... but are there plans for any type of splitters??

Mini-USB/3.5 stereo
Mini-USB/2.5 stereo
Mini-USB/2.5 headset (TRRS right?)
or even Mini-USB/2.5 stereo with a mic and call button like the "AUDIO ADAPTOR (E.MINIUSB TO 3.5MM) WITH ONE-TOUCH/MIC" (i would be very interested in this one)

http://www.semsons.com/2miusband3st.html

Buy that, problem solved, and it's dirt cheap and sits flush with the Mogul.

two reasons im not a big fan of the semson adapter ... it has a bulky obtrusive look underneath a device with a small attractive form factor (at least compared to similar older PPCs) ... and over time im pretty sure it will put alot more wear on your device's ExtUSB socket or worse considering its one solid piece with no flexible joints and all its weight and leverage are supported by the plug ...

hence my comment to the seido guy
"looks awesome ... much less obtrusive and stiff(dangerous) than semson's product ... but are there plans for any type of splitters??"

Yes, it seems to me that someone should be able to make a multi-adapter for the HTC devices. One that included both 2.5 and 3.5 mm sockets, with a mic built in to the adapter that could be overridden by a mic that came built in to the headset. That should cover all the bases.

The Mogul would look like an octopus with all the multi adapters dangling from the mini usb port! Man, i'm using my ipod now more than i did with my 6700 because of this.

An even cheaper solution:

Thanks! That's a little cheaper than Seidio.

im sure somebody can come up with either a design with inter-changeable ends (like the old radio shack universal ac adapters :D ) or offer a wider range of models (hopefully including some from the list i wrote) ... seido already has a few options and i hope they understand most of the people in their customer base for these types of things demand customizability and will work on it ...

Just received my adapter in the mail from Seidio. It doesn't work :(. I tried different headsets and I am not getting any sounds. The Mogul doesn't detect that there is a headset. I tried plugging in the headset to the adapter then connecting it to the phone, it didn't work. So I connected the adapter first then connected the headset, nothing. I guess I will have to RMA this.

What is yur order # ? want to make sure you got the right one !

Seidio

My order # is 78062. The packing slip listed the part # as ADA-11PM35FST and the label on the bag containing the adapter listed as ADA-11PM35F. I have already requested an RMA but if you can make sure I get a working one then great!

Has anyone tried modding the headset that comes with the Mogul? I was thinking of attempting to replace the headphones with a jack myself. Seidio's adapter with a microphone is tempting, but the face that the mic is so close to the phone itself sorta makes it less appealing.

That sucks. I bought the same one and I'm waiting for it to come. Looks like I will need to do a return before i even get it.](*,)

Guys,

Search for this item (#SGEY0003602) on ebay. It originally comes with the Sprint Fusiq and is exactly what some of you are looking for (2.5mm to 3.5mm with built in mic/button on the end). I know it's not usb to 3.5 but it's still a good find.

Here's a link to an auction for one that already ended: http://cgi.ebay.com/ws/eBayISAPI.dll...EWA:PIC&ih=012

I just received a replacement adapter from Seidio. It works! Apparently, the first one was either defective or the wrong part. The first one I received came in a bag. The replacement I just received from Seidio came in a plastic box. This one works! I love the adapter since it is so low profile. Seidio sent me the replacement even before I sent back the defective one to them. Great customer service!

I bought that adapter only to discover that it stays in headset mode as long as the adapter is plugged in, even if the headphones are unplugged.

So if you're wearing your favorite headset (w/o a mic) jamming on some tunes and you get an incoming call, the only way to answer the call is to unplug the adapter since the phone's mic is automatically turned off.

I have tried using the speakerphone during call, but while it acknowledges your button press, the speakerphone is permanently off as long as the adaptor is plugged in. Which is odd because the speakers are loud and clear when the phone rings for an incoming call.

Because of that, I'm guessing it's a software issue as the phone assumes that you're wearing a headset with a built in mic. HOWEVER, the 2.5 headset adapter that comes with the Mogul does allow the Mogul to know when the headset is plugged into the adapter and it will allow you to take your call on speakerphone.

I'm thinking that with a little more quality control, the adaptor would be able to tell the mogul that a headset isn't plugged in. Since that isn't the case, is there a tweak to override the software to allow you to use the speakerphone while the Semsons adapter is plugged in?

Great question, but noone ever replied to it. I am running into the same issue with my Touch. I might have to buy another adaptor with built in mic. grrr

what exactly is the adapter that came with the mogul used for? it has a headphone image on it but my earbuds dont fit. cant seem to find a use for it.

I bought this a long time ago for my Mogul and it works fine:

Will this adapter work?

Re: Mini-USB to 3.5mm Adapter
 

I had this problem for my older phone. Radioshack sells nice little 3.5 to 2.5mm adapters and vice versa, so I'm assuming they'd have something along the lines of what youre looking for.
