Making Headphones To Fit Mini Usb

I want my in ear headphone to connect to my phone but it uses mini usb, so i have brought a mini usb connector end from a computer shop in town, ive got a old set of headphone to cut up but what pins on the connector do i soilder the wires to???

The plug for the headphones is not a standard mini-USB.
You need a headphone adaptor lead from eBay or somewhere.

I know mate, i need to know what pin on the phone runs the sound then i know what pins to connect my wires to on the usb connector and my earphones.

Custom earphones to usb
1. leave the usb plug alone, the first possible point to grab analog audio is the mic/volume slider combo.
So, either pry open the small mic/volume slider box and solder your new headphone cables into that (make sure to remove the isolating paint from the wires (e.g. by burning),
or open the original headphones and your new ones and just resolder the headphone cables - my recommendation, for usually being easier.
have fun

i remember seeing an article on one of the PPC websites 6-12 months ago when the artemis was still a new device. the article showed step by step instructions with photos and even specified the components required.
unfortunately, i can't remember where i saw it (sorry) but at least you know it exists and with a bit of help from our google friends, you may be able to find it.

HTC ExtUSB Extension Lead? Custom USB Leads?

Has anyone ever come across a male to female ExtUSB extension lead?
Google and ebay throughs up nothing. Perhaps someone knows of a company (UK ideally) that makes bespoke USB cables? I think I'm going out on a limb with this one.

First, I dont have any exact solution for your problem, but I'm wondering, why are you looking for that?
If you were to do an extension on the data cable, you can get yourself a standard USB extension lead, and have the data cable extended.
If you were to do an extention on the audio cable, you can get those extUSB-to-3.5/2.5mm audio-jack and get a standard audio cable/earphone for the job.
UPDATE: Ok, I see what you are trying to do in http://forum.xda-developers.com/showthread.php?t=342382
Can you elaborate the 3-in-1 thing you mentioned there? it is just a splitter/hub, which uses extUSB for all?

Great investigative work Hanmin. As you saw the objective is a car 'install' with one wire leading to the device (kaiser), and the 3-in-1 adtaper hidden away. So the extension needs to be about 1meter and carry the HTC ExtUSB spec of power and audio signal (hands free doesn't matter to me though).
In actual fact, a 3-in-1 adapter with a 20cm lead would be sufficient, but none of them seem to be longer than 5cm.
The extension can be found here. Or image attached.

Anyone come up with an EXTUSB extension cable? I'd really like to have just one cable coming out of the phone when in the car, and keep the splitters tucked away neatly behind the dashboard.

See the first link in post#3... http://forum.xda-developers.com/showthread.php?t=293357
I just ordered two of them, but haven't received them yet. They emailed that they shipped from Honk Kong the next day. however!
Hope this might work for you!
***UPDATE*** I just received the cables today (1/4/08). Just what the doctor ordered! I use it with the Motorola Mini-USB "Y" adapter SKN6222A to power both my phone and a bluetooth GPS head from the same power plug. The extension lets me keep the phone mounted on a dash vent and the GPS on the top of the dashboard.

Posted in the thread linked above as to why that doesnt work for me, anyone come up with a way to extend the 11pin extusb? Im crap with a soldering iron, but if it comes to it...
Im in the exact same boat as the OP, have the 3 in 1 and it looks horrible with the 3 cables dangling out of it, want it hidden behind the dash.

Again, not exactly what you are looking for but maybe of use. The Brodit HTC Touch Pro Holder with 3-in-1 Adapter (http://www.expansys-usa.com/p.aspx?i=173938) is a mount with an included 15cm extUSB to 3 port adapter. Not sure if the 40cm cable is long enough, but it could be taken off of the mount i would think. A bit of a waste to have to buy a mount just to get a cable, but might be your best option.
I don't understand why no-one has made an extUSB extension cable or a longer extUSB to 3 port cable.

german company sells the plugs, so you could make your own cable...
wanna order a few and let us know how it turns out?

Hey all. I resell ProClip products and have been trying to help out some customers with solutions for their Hero in the car. Looks like no one has any stock solutions for a longer cable to create a cleaner install outside of buying one of these:
ww_w._proclipusa.com/image.aspx/media/images/products/devicecradle/843773.jpg-225x
(sorry. can't post links yet. how do I go about getting verified?)
and disassembling the cable. So who'd be interesting in buying that 15.75" cable separately? I'm working on getting them to sell the cable separately. That'll be the first solution for HTC owners. My second attempt is getting them to make an adjustable holder for HTC phones and see if they can make the height of the connector adjustable. Since they'll never make that kind of cradle for all HTC phones, at least they can cover all their bases with that type of cradle.
Let me know if anyone has interest, and I can keep you posted.

i will be keen on the extension cable! I have the same problem as trying to hide the fm transmitter and also an adaptor (to charge the fmtalk & phone at the same time...) in the car.

Micro USB pinout?

I have googled for quite a while, and have not found the pinout on the microUSB port. I really want to know if there is any way to get analog output from that port like my old G1. It would be nice to have one port for charging and audio (for cars, docks, and boomboxes).

Thanks for that. But I wonder how that port will provide audio with something like this?
http://cgi.ebay.com/Micro-USB-3-5mm...ewItem&pt=PDA_Accessories&hash=item35a8ba858b

ok, I am just curious, but you dont want to use the audio output on the top of the phone just to have an all in one solution, correct? Because I have no clue what would happen hooking that adapter up, curious though.

It has to be built into the port as well as the software to control it. I've got my money on it not working, since it's not supported by the phone. HTC ditched the USB headphones a while back because everyone complained about having to use special headphones and adapters, hence why they all have standard headphone jacks now.

Exactly. Having a dock or boombox that would be plug and play would be nice. I'm actually considering something for the car that would replace a head unit. Maybe there would be a way to snag the digital audio from the HDMI port? Digging continues.
Worse case scenario, I use the USB port for power and bluetooth the audio.

I dont think it is possible through hdmi without a digital to analog converter, which are rather expensive. The hdmi out is pure digital goodness.

HTC ExtUSB Micro?
I am looking for the same info.
Is the micro usb port on the evo just a standard 5 pin only?
The mini usb on the hero was the non-standard HTC ExtUSB with 11 pins. I loved this because I could make my own docks that included power and audio with only one plug.
Maybe the HTC micro b is analogous? HTC ExtUSB Micro?

I dont think so, it's only 5 pins. And I think the only reason HTC had the 11 pin was to provide the proper support for audio out. Since the evo has a 3.5 mm I dont think it is even possible to do that.

And how exactly do you intend to convert the HDMI to a digital RCA or TOSLINKi nterface as that box requires? Oh, another $50+ box? Yeah, that's what I thought. So, $100 or a cable that looks "silly". I know where my money would go...

The Samsung Fascinate has this audio/usb option. Their docking station has a micro-usb plug and then a USB (power) jack and a standard audio jack out. So it doesn't require any special decoder, there must be audio out pins just like in the iPhone/iTouch?

Take a peek at this photo of an Evo's circuit board. Specifically, the solder points for the microUSB port (including the ground/anchor points):
http://guide-images.ifixit.net/igi/22dlA5ZuptWCyvTX.huge (from http://www.ifixit.com/Teardown/HTC-Evo-4G-Teardown/2979/1 )
Count 'em. Eleven, just like extUSB on the Hero & other HTC phones. Looks like the Evo has what could legitimately be called a "HTC micro-extUSB" port, and not merely a standard "micro-USB" port.
Now... good luck trying to find a CABLE with all 11 contacts and wires on it. If it exists, Digikey probably has them... but god only knows where that needle might be in their million-part haystack (anyone who's ever tried finding a specific connector, even a common one, at digikey.com if you don't know its exact OEM part number knows the joy I'm describing...)
Chances are, there's a (~2.7v) serial UART sitting on two of those pins, too.

Nope. It's definitely the Micro USB connector. I know this is an old thread, but I've been trying to do some research on this port in hopes of hacking my own car dock.
I've found some additional information on this Micro ExtUSB™ port. The HTC Incredible uses it for its TV Out port. See this Thread on AndroidForums. There's even a special cable for the Incredible at HTCPedia. I'm very tempted to buy the cable to use it as a sort of breakout box to experiment with this port.

I believe your looking at the micro hdmi port, the usb is indeed 5 pins.

I'm pretty certain it's just a standard 5-pin MicroUSB port. Just shining a flashlight into the port, I only see 5 pins.
It would be really nice if there was a standard connector that supported power, USB, audio, and some sort of control bus. The Apple dock connector is a bit big, but it allows for a lot more than microUSB can do. Though I guess it could be done over USB if there was a standard for it.

micro female/male hdmi and usb for Lapdock

I bought these on ebay. The HDMI is short but worked but when I connect both cables to lapdock, the USB is not being recognized so the keyboard/mouse is not working. I want this just to act as an extension so I can use full lapdock abilities with cables. Any idea what's going on (cable charges on plug but does not charge on lapdock)? Maybe someone has better usb cables.

i don't think it will work either way, tried a few things like this with no avail.

why wouldn't they? Cheap build quality that doesn't include the data wires? Hell I'll be willing to splice two cables together to get our desired effect, the only problem is that cords with a female micro usb are incredibly hard to come by

So that is what you think it is? No data on the usb cables.

the only reason that is my suspicion is because there are many "charging" products out there that don't really need data. Why there would be a need for such a small charging extension cable is beyond me, but it's the only solution I can think of, but I have no way of confirming or denying it either. The ebay descriptions seem to imply that the data wires are there, but we all know how reliable ebay can be...
Another idea I had was that it might be sensing the resistance in the cable, since, if I remember correctly, that was how some think/though the car dock puts the atrix into car mode without a magnet as is/was commonly used. Again these are just ideas.
Or the cable is just so poorly made that it's defective...I honestly have no clue

Has anyone got full lapdock capabilities using extension cables? I can only get the screen working and not the mouse and keyboard.

The HDMI extender was the hard one to find. There are other micro USB extenders out there, theoretically with all wires connected....

Kind of makes me wish i hadn't hacked up my lapdock to work with the Otterbox

Where did you get your HDMI extender? I got mine from All4Cellular but it's quite short. Will have to get another HDMI one if the usb cable you recommended works.

The HDMI certainly looks like it may work but the reason I didn't buy that product from ebay a few weeks ago was because it was $50. Now miraculously, it's only $6. Maybe I'll get that if the USB cable I just bought that was suggested works a few posts back.

The HDMI cable seems to work. On the lapdock, with just the HDMI cable hooked up, it functions like it was it's an entertainment center.
The USB cord will need to be modified a little bit. I can't get it to seat right on the USB jack of the dock. I'll need to shave it down a bit as it doesn't sit down snugly.

I ordered the USB cable and experience this same problem, though I am waiting for my hdmi parts to come in (by April 6th I should have all my parts...). The cable itself works flawlessly as a micro usb extension cable when connecting it to the computer.

again as mentioned in the other thread, you want to be careful with the 5v coming out that micro hdmi port. for connecting back to your phone would be no issue, as the phone charges using this voltage, but hooking the lapdocks micro usb up to a host device probably wont appreciate the 5v coming back up the cable, where normally the usb device would be pulling power from said host, not providing it.
one suggestion is to just clip the red wire inside your micro usb cable/adapter.
btw the adapters i use do fit snugly side by side, without modification.

I've been following this thread for a little while now, and I wanted to share something I found.
I was looking at the Motorola Travel Webtop adapter. And I was curious to see whether it could be tweaked to suite our needs. I naively thought/hoped that I could flip the connectors in the device to make a small adapter to connect the Atrix to newer Lapdocks. Unfortunately as you can see in the pictures below (sorry not enough posts to link to the pictures) the two connectors are connected via a PCB not wires or a ribbon cable. Although I still have high hopes that I can de-solder the HDMI and USB connectors, and use a small length of flat ribbon cable to connect them and then re-positions the connectors in the case, to build a micro adapter to use the Atrix on the newer Lapdocks. Should this fail this will at least prevent others from making the same mistake, and solve the mystery of what's really inside the Webtop Travel adapter.

Do any one know if this Micro HDMI Cable would work for Lapdock.

1 "PC" to 2 USB switch - for in car USB switching *RESOLVED*

Hi Guys,
I have an odd request! currently working on a car pc project with my nexus 7, and I need (for very long winded reasons!) a "1 pc - 2 USB" switch. I have bought one I thought was a great deal, until it arrived, and I realised, its actually a 1 USB to 2 PC switch... Since I dont have the right cable for it, I cannot really test it, however, I dont know if these or uni, or bi directional communication! in which case, if they are bi directional, it will work, but if they are uni... I am stuffed!
Anyone got any thoughts or a link to a good piece of hardware?

for anyone who comes across this in the future, I have manufactured a solution!
First, buy yourself a switch: I got the 12 terminal four point variety:
http://www.ebay.co.uk/itm/291477511265?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT
Second, get yourself some USB cables, I bought a couple of small USB leads, but depending on what you want, I would recommend buying longer leads (Hindsight!)
Third, because I want to be able to disconnect all of this, should I need to remove the switch from the car whilst disassembling, I also bought bullet connectors with sleeves.
Basically, cut the male end off a USB lead, strip back and cut off the shielding. Attach each of the four leads to a separate male bullet connector. Attach the male USB to the four central posts of the toggle switch, by pushing the male bullet connector (using the hole in the middle) to the posts. this is the output.
Do the same with two female connectors, strip back and cut off the excess, attaching each to a bullet connector.
Now all you need to do is take each of the two males and connect them to the posts of the toggle switch, matching the wire colours to the male output. Job done.
I thought this wouldnt work but gave it a go, I then connected it to my PC, and switched between two USB devices, and copied files over, and validated they were correct, so it seems to work quite well.

Thank you.

Good share!

Thanks
