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.
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.

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.
extension cable
I would love to buy an extension cable
Quite a lot PDAs supporting USB-host, but for only a few an adapters or appropriate cables from the manufactures are available.
As these devices support USB-Slave as well I would like to know if there's a way to convert the USB male connector (used as slave e.g. for sync with the PC) to a USB-host female in order to connect accessories (keyboard, mass-storage devices...).
According to wikipedia the configuration of the pins shouldn't differ too much for slave and host mode.
Pls. see attachement, that's what I found regarding this question. It's a picture showing a similar configuration (as new user I'm not allowed to post external links, thanks to ab21cn
from xdaflameusers)
But it's a male-to-male converter and furthermore a converter from "big usb" to micro (mini?) usb. As there're already standard converters for the different sizes of USB I would like to start with the biggest size and to buy the appropriate converter as needed.
Does anyone has a circuit diagram or any other idea for such a generic converter?
Try adapters made for Nokie N800 series
I had a Nokia 770 a couple of years ago. It came as USB device only with mini USB connector, but online I found how to upgrade the software to USB host, and use a cable adapter. The plans I found online involved a 9V battery and 5V voltage regulator inside a metal case (they used a penguin mints case). I built one of those, even using the penguin mints case, and it worked fine.
I have never seen any indication that my HTC phone would work the same, but I am guessing that it might, if the USB host drivers are available.
Google couldn't locate the penguin mints-based converter I originally found, but this seems to be a similar circuit diagram.
Edit: Found it!
thx
thanks for the links. but i'm a little bit afraid of connecting something to my pda which has an own power supply, the risk of a burn-out is given. i've got a nautiz x5 with 4400mA battery which should have enough energy to supply usb-power to connected devices.
I think I'm going to contact the manufacture of my device, maybe this works for me, but a generic adapter would be of use for anyone.
the chips used for usb should be of the shelf as i don't think each manufacture develops an own logic for usb... but this doesn't imply that the cabeling is standard too.
what the heck makes manufactures providing features in their products which the users can't take advantage of?
do you mean using keyboards and so on on ppc?
because it's so simple if ur phone has a mini usb plug (the one u plug the power adapter into). i found a cable that plug into that and plugs a normal usb cable in on the other side and blam been typing on my phone using a desktop keyboard. it depends how much power your device requires however. i wish there was some software to feed a video line out so i could watch videos on pair of vizors that wud be rad. all i can find is a mini-sd card converter now whats the point of that. guess i need an itouch
yes
primary i want to connect usb mass storage devices to my pocket pc. gamecontroller or keyboard would be a good thing too.
my devices doesn't have a standard usb plug, the only thing i got is a adapter from the properitary plug of my device to standard usb male connector, but this is meant for usb-slave use only.
the underlying qeustion is, if there's a way to convert usb-slave to usb-host using the same pins. if it needs an additonaly pin then i don't see a way to convert it as i don't know anything about the pins cableing of my properitary plug.
a week ago i found an adapter which was able to convert the male usb to another male usb... but it didn't work.
the problem is compareable to datatransfer between two pcs via usb - it's possible, but only using properiatry hardware and drivers...
so i think there's no way to solve this problem in a generic way.
out of interest, do you already have windows CE drivers for the device to act as a host and mass storage? I wouldnt mind them if you can point me somewhere..
how to check if my htc (touch2) ca use usb host?
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).

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.
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.

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....

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 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.
