Hi All
I, like many people, use my orbit and now orbit 2 as an mp3 player. I have a few headphone adapters which allows me to use normal headphones which sound much better than the stock o2 ones. Not a bad solution however when a call comes in you have to unplug the headphone adapter to allow the phone mic to work. Having the adapter plugged in disables the phone mic.
I was wonder if anyone had any ideas on how I could 'fix' the headphone adapter so that it no longer disabled the mic. The theory is that should a call come in i can keep my headphones on and simply hold the phone up to my mouth to talk. My look a bit odd but it will save all that unplugging/replugging.
Thanks in advance
Jeff

assuming it's the same...do you think I just break off pin 1 ?

I doubt it's that simple. I really, really wish I could find it again but floating around somewhere on the web is a site that has a proper wiring diagram as well as just the pinouts.
From memory I think there's a pin held low (or maybe high) somewhere to tell the device that the adaptor is plugged in. I don't think that just the presence of a connection to pin 1 is what does it.
My suggestion is to open up the plug on your least-favourite adaptor (to experiment in case you trash it) and look for internal links between pins. My guess would be that either one of pins 4 or 5 is not a genuine Gnd signal but is actually a pin that is held low (i.e. set to Gnd) by the headset adaptor via a link from one of the genuine Gnd signals coming in on USB pin A or the other one of pin 4 or 5 . Alternatively one of pins 4 or 5 might be asserted high by a bridge to pin E. Finally the USB NC pin (pin B) might be the detector pin and asserted either high or low via a link to one of the Gnd or +5V input pins.
What you really have to hope for though is that two of the above are true because if there is only a single pin on the plug that is either asserted high or low to allow the detection of the presence of the headset then you're really out of luck because it is then extremely unlikely that it will separately detect that the speakers are plugged in but the mic isn't so, when you identify and disable the appropriate link, you will probably also re-enable the speaker in the handset as well as activating the mic.
All the above is guesswork I'm afraid, but I am a computer hardware designer so it's not totally uneducated guesswork, so you really will have to experiment or find that wiring schematic I spoke about, but the basic message is to look for links asserting some detector pin (or pins) high or low on the connector.

P.S. I can't think of any way that you'll break anything just by cutting links but be very careful not to short out any existing connections because that could damage your device and don't create your own extra links unless you know exactly what you're doing.
A similar question has been asked on modaco but I don't think a solution was found. Therefore I am going to ask if this would work here.
Is it possible to connect a micro usb (male) to mini usb (female) adapter up to this thing (HTC 4 in 1 adapter: I can't post link because I am a new user but just search it on youtube). This would connect to the tg01 micro usb and provide a 3.5 mm audio out in addition to a mini usb connection where one could potentially hook up a charger. I was thinking of testing this out as it would cost about 10-15 dollars but I do not want to damage my phone in the process. I have no electrical engineering knowledge but maybe someone else can explain if this would work before I order anything.
On a side note: I order samsung WEP870 bluetooth headphones on sale as an alternative to this. Note sure how sound quality is but I will try answer any questions you guys might have.
Any input is welcome.

I was heavily involved in the discussion running on MoDaCo you refered to; unfortunately there has been no breakthrough on this issue to date.
I did look into the the HTC adapter you mention, but it actually uses the proprietary HTC ExtUSB plug on the input end (connecting to the phone) and NOT a normal mini-USB. The ExtUSB has 11 pins which include a discrete audio output (being used to feed the 3.5mm jack socket) and also hard-wired power (used to accept the charger input).
In the case of the TG01 uUSB socket, it is too 'intelligent' for its own good. Every function, charging, audio out, USB data transfer, etc., is under procesor control. Different functions are triggered by the device 'seeing' a certain resistance across the sense pin and ground; depending on this the processor then configures the use of the socket pins accordingly.
I am after what you are trying to achieve also; there is a chip supposedly available which is intended to fulfil exactly this functionality, but I've been unable to find any devices on the market which use it and attempts to contact the manufacturer with a view to getting a few samples to try and build an interface have so far been unsuccessful.
I've attached a couple of documents which explain the uUSB Charger Adapter and also the chip spec sheet for reference.
View attachment MC34825.zip View attachment batt_charging_1_1.zip
If anyone else knows anything to help move this one forward, will be much appreciated !
Thanks for the nice explanation,
Hopefully one day there will be an adapter that can make this possible.
Hi guys,
I bricked my G1 recently and am going to try to Unbrick using the guide on cyanogen's wiki.
One requirement is the debug serial cable, but here in India I haven't been able to get my hands on the ExtUSB breakout. I do have a mini usb breakout. Could I use that instead?
The pins I need are:
1 VCC
2 Ground
3 tx
4 rx
The pins available on the mini usb breakout are:
A +5V
B -Data
C +Data
D N/C
E Ground
Pretty obviously:
1 -> A
2 -> E
Goggling tx and rx, I think they mean data in and out but not sure. Anybody have any advice?

ExtUSB is backwards compatible with mini USB: http://en.wikipedia.org/wiki/Universal_Serial_Bus
I have several mini USB cables, some with a Type A male connector on the other end, others with a wall plug end, and still some with the cigarette lighter adapter end. They all work with the G1. The 2 extra pins on the ExtUSB are for sound only.

Ah, when I saw serial I thought, "why is he calling a USB cable by only part of it's name" (universal serial bus). I misunderstood the post and did not think he was talking about an actual serial/RS232 connection.
So as to try to contribute something to OP, have you tried looking at this? http://www.instructables.com/id/Android-G1-Serial-Cable/
I was doing some study connect my serial GPS (gives TTL level serial signals) to HTC P3400 WM. Found out about G1 cable in instructables and other materials that explained how to use serial ports in HTC mobiles. I came across a very cheap "adapter" in a roadside shop in Chennai - one end of this one goes into the mini usb and the other end provides a 3.5mm stereo audio jack. I grabbed one of them and surprised to find that it did not have the moulded rubber connector. I opened the plastic case and found that I can easily solder pins 7,8 and 9. I will be testing this over the week end!
Thanks for the info Xsite_01, i think i can find some headphones to cut up and give it a try.
If smpncrc's adaptor works, i'd love to get my hands on it in delhi.
Thanks for all the info guys
Someone asked help on our local forum about this and I thought it might also be of help here, so here goes my share.
If you are like me who wants to carry only a small cable for charging and data transfers, you'll find it hard to get your hands on a good micro USB charging/data cable. Buying micro USB charging/data cable for Samsung is tricky since the wiring can be different from the normal USB cable. There should be 5 pins on the micro end, but sometimes there are just 4. But Samsung cable uses only 4 pins that might have been rewired. I'm not sure whether only Samsung does this or the same can be said of the other brands. There are also micro USB cables being sold that does only charging and no data function, and vice versa.
I've grown tired of searching for a cheapo charging/data cable that doesn't deliver the function, so what I did was I bought micro USB to USB adapters instead and bought a normal female-to-male usb cable extender just in case the fragile cable wires get broken again they can be easily replaced. They get the job done. You can also use the other gender adapter and cable combo but using the same combo that I use enables you to charge and transfer data with just the adapter and without the cable in case the fragile cable gets damaged.
They charge the phone as fast as what the USB power brick provides and what the phone can accept at the same time. :victory:
This thread was opened with the intention to help others to easily find an almost guaranteed working data/charging cable combo because not everyone has access to a cheap branded cable. (And sometimes even a branded cable does not guarantee both functions). This is a quicker guaranteed solution for those buying micro USB cable that has no way to test the cable they are purchasing, mostly those buying online or those buying impulsively.
The logic behind the "almost guaranteed working data/charging cable combo" is that unlike micro USB cable, an extension cable guarantees that every pin has its own wire with no modifications, that's why it is called an extension cable. The micro USB adapter, guarantees the full conversion from micro USB to USB interface to have all pins connected properly, that's why it is called adapter/converter.
So, if you do not like the idea of the extended length that is protruding out of your micro USB slot, this thread is not for you and you are not obliged to use or try the setup in any way. The solution provided here is not perfect but a fully functional solution.
I hope this can help someone.

No offense, but that is a seriously stupid idea. Do you have any idea the amount of leverage that contraption will put on the μUSB port? Hit that wrong or yank it too far and it will snap the port right off the board.
There is absolutely nothing special about any Samsung charger or cable. They use standard, straight-through A-B cables just like every other phone. The chargers themselves conform to industry standards, whereas + and - are on pins 1 and 4, and the data pins are tied together in order to trigger the phone into high current charge mode. The "B" end of a mini/micro USB does have 5 pins - the extra pin is for an ID resistor (referenced to ground), so the phone can identify when it has been inserted into a desk or car dock. There is no corresponding pin on the "A" end, and the lack of an ID resistor or the physical pin will have absolutely no effect on charging.

The same goes for the charging flap. Anything that is applied too much force will break. I've been using it for almost a month now and everything is fine. It's just an alternative, maybe a short-term substitute for the oem usb cable if you want.

Of course anything can be broken given enough force. But it takes far less force to break something when you have effectively quadrupled the length of the lever. The stock cable's plug is 1/2" long. That contraption is easily 2" long. That's the same reason you don't use a one-piece solid adapter to plug 1/4" headphones into the 1/8" jack on your phone. It's 6th grade science.

Considering you are the only one to have this "problem", Mod Edit – Some content removed . USB is USB. That's the entire point of adhering to standards. There are no "special" or "rewired" cables for Samsung, nor does any current Samsung device (with the exception of the Tab2 10.1) require any proprietary cable or charger. If a device's connectors do not adhere to the published USB standards, then the USB name and logo can not be used under penalty of law. A company can use the technology in a non-standard configuration, but it must have a distinctly different connector and can not use the USB marks.
And no, Samsung bundles 4-pin cables. So the phone can't identify when it has been inserted into a desk or car dock?

WTF are you talking about? The standard "A" side of ANY USB cable only has 4 pins. There is no such thing as a 5 pin standard "A". The μUSB JACK on the phone has all 5 pins (well, technically 10, since it is USB3.0, but the extras aren't pertinent). μUSB "B" end of a CABLE does not use the ID pin (pin 4), because it does not need to - so whether or not it is physically present in the plug end is moot, because even if it is there, it's not connected to anything. The only thing the ID pin is used for is for situations where the phone needs to know when a certain device is connected. If the ID pin is connected straight to ground, the phone knows that an OTG adapter is plugged in and it puts itself into host mode. If it sees a certain resistance to ground, it puts itself into either car mode or dock mode depending on what resistance it sees.
And for the record, most of the posters commenting in that thread you linked to over at AC are retards. Especially the OP, who claims to "know for certain" that the S3 uses a connection with reversed pins. Because just like EVERY OTHER PHONE WITH A μUSB PORT, the S3's jack follows the USB standard pinout.

It won't work, because it's not an actual OTG adapter. It doesn't have the ID pin tied to ground in order to put the phone into host mode.
This made me LOL
But yes any A to Micro USB cable will work. However, if you use the provided cable that Samsung gives you it will charge quicker by using the extra USB3.0 plug.
But, my S4 charges just as fast as the standard OEM cable they provided when using my Galaxy S2 or any other quality USB A to Micro USB wire. This however is not true when using junk/cheap USB cables irregardless the USB plug ends. The wire quality is usually pants compared to other brands. Some of the cheap USB wires will even show a resistance on an ohms meter.
In the end, the OP is making a very complicated USB plug for their phone Just buy a quality USB cable from walmart ebay bestbuy etc

Sorry, but that's wrong*. The 3.0 plug only adds extra data pins. Power still runs through pins 1 and 5. It will charge faster if you use the provided CHARGER - because that outputs two amps, versus the 3/4 to one amp output by older/generic chargers. The S2/S3 came with one amp cube chargers, the S4/S5 came with a two amp. The ones you find at gas stations are generally 750mA to one amp. But it does not matter if you use a 2.0 or 3.0 cable to get that charge rate, because it is dependent on the charger, not the cable..
[* the 3.0 standard does call for higher power capability when connected to a computer port - the device can negotiate up to 900mA from the host while simultaneously transmitting data (USB2.0 specifies up to 500mA). However this is still lower than the power that is available from the supplied charger.]
As far as sourcing cables, you absolutely can't go wrong with Monoprice. They have the high quality cables with the glossy, hard plastic plug grips (just like what comes with Apple and high end Samsung products) for $3..

It's because you can't, in any way. First, you don't have that capacity. Second, those " well-documented, globally recognized industry standard" is not for the "USB" that you re referring to, therefore they don't exist. "USB" is not the whole device or cable itself, but the receptacle & plug and how they will transmit power and data. They don't specify how the device should deliver them. In fact, you can attach another device in the cable between the USB ends.
Taz420nj said:
USB is an INDUSTRY STANDARD. That means in order for a manufacturer to be allowed to call a device "USB Certified", the manufacturer MUST ADHERE TO THE STANDARD'S POSTED SPECIFICATIONS. It does not matter whether the manufacturer chose to use a standard, mini, or micro USB port. It also does not matter if the manufacturer uses a dual-purpose port (such as a USB/eSATA hybrid port on a laptop) or proprietary port (such as Samsung's 11 pin Micro USB) - provided that the port is BACKWARDS COMPATIBLE (there's that obscure word again) - meaning that still adheres to the posted specifications for pinouts and connector dimensions for the USB standard.

I'll say it once again, the USB standard is for the connectors. Anything beyond the connectors and the immediate wires connecting on the pins are not covered by the standard that you claim.
So, just for everyone's information, and since I am already tired of your continued spawning of nonsense and making others ignorant as you, I will explain everything in detail in layman's term. Although, I doubt that eenie weenie pea-size object in your cranium can comprehend them. But nonetheless, I will have maximum tolerance for the handicapped in this thread. Be sure not to post any blabbering anymore, because your ignorance is being broadcasted worldwide.
USB is a plug & socket standard, just like your power plug and power sockets. They have their own standards set by the governing bodies to ensure universality among electronic devices to ensure that they fit and function. Like the power plug, the USB has + and - wires, but with added wires for data transfer. The standard refers to the physical dimensions and positions of the plug and function of the pins, as well as the code classes, but anything beyond that other than the voltage are not covered by the usb standard. If they were also included in the same standard, there won't be innovation. It will be dictating something like a power plug can only be attached to an electric fan and cannot be used elsewhere. The wires inside are also not obliged by the standard to be present. Although there are 4 pins, they are not required to be all used and attached electric wires into. This is the reason why you can't say that all USB cables are the same and will function the same, and that especially applies to micro USB cables. They look the same but you will not know the difference until you use them or slice them open.

For your statement that you keep on insisting, your tribe was obviously left out by civilization. For charging/data cable, which this thread aims to give alternative to, you need the correct micro USB cable, using just any micro USB cable that you come across won't guarantee that it will supply power for charging and do data transfer.
Regarding length, you cannot use just ANY LENGTH because the signal weakens after a certain length. You will need to attach a booster to maintain that transfer speed longer than that length.
http://en.wikipedia.org/wiki/USB#Cabling
The USB 1.1 Standard specifies that a standard cable can have a maximum length of 5 meters with devices operating at Full Speed (12 Mbit/s), and a maximum length of 3 meters with devices operating at Low Speed (1.5 Mbit/s).
USB 2.0 provides for a maximum cable length of 5 meters for devices running at Hi Speed (480 Mbit/s). The primary reason for this limit is the maximum allowed round-trip delay of about 1.5 μs. If USB host commands are unanswered by the USB device within the allowed time, the host considers the command lost. When adding USB device response time, delays from the maximum number of hubs added to the delays from connecting cables, the maximum acceptable delay per cable amounts to 26 ns. The USB 2.0 specification requires that cable delay be less than 5.2 ns per meter (192 000 km/s, which is close to the maximum achievable transmission speed for standard copper wire).
The USB 3.0 standard does not directly specify a maximum cable length, requiring only that all cables meet an electrical specification: for copper cabling with AWG 26 wires the maximum practical length is 3 meters (9.8 ft).
This is, again, straight from wiki:
To reliably enable a charge-only feature, modern USB accessory peripherals now include charging cables that provide power connections to the host port but no data connections, and both home and vehicle charging docks are available that supply power from a converter device and do not include a host device and data pins, allowing any capable USB device to charge or operate from a standard USB cable.
http://en.wikipedia.org/wiki/USB#Connector_types
This is particularly evident in most micro USB cables bundled with powerbanks. The powerbank requires only to supply power and it doesn't need data transfer. So, it is more logical to bundle data-less cable so that the material acquisition cost could be lowered. The opposite can said about older cellphones that are bundled with proprietary charging cables that have micro USB slots for data transfer. Most of their bundled USB cables do not have charging capabilities, although some can still be charged when plugged into the computer.
And also, this proves that USB cables do not provide the same current or amperage. And also proves that not all micro USB cables will charge your device at full speed due to different resistance which the caveman has still failed to answer. The OP provided visuals, so I'm hoping the caveman can at least recognize them. This is a factual data and not some blabbering blah-blah-blah from someone obviously left out by time.

It is not just about the "connectors and the immediate wires connecting the pins", the USB standard lays out EVERYTHING, from the connector dimensions, to the pinouts, to the cables, to the power transmission levels, to the data transfer. If a device does not comply with those standards, then it can not be legally called "USB Certified".
