Just got a Mophie juice pack for my iphone. I want to connect the male 30 pin plug from my ClearScan Live radio interface to my iphone ( which now has a usb female jack into the mophie. I searched the interweb for converters that take a 30 pin male plug and output to a microusb male plug. I can find the exact opposite of what I need. Has anyone run across such an adapted?

I think the simplest solution to give you would be to get the Camera Adapter, which provides a USB female-A jack, and then a standard A-to-microB cable. I'm not completely sure what kind of data would be permitted across that by the OS, but it's something to look into.

Hello everyone! My name is Patryk Andrzejewski (don't try to read my name if you're not polish), and this is my first thread on XDA.
I am studing electronics on university of technology so i'm pretty well with all kind of electronic stuff.
What i'm trying to do is "x-ray" the usb port in our TG01.
My basic targets is to find way to charge the device while using USB HUB or while listening music. If it's even possible to do.
Right now I know how to connect TG01 to amplifier by 3.5mm plug. Generaly most amplifiers have high impedance input while tg01 expect low impedance earphones to switch usb port to audio output. So what we need to do is take two resistors with the same resistance around 10k Ohm and connect them both between ground and both signal channels in male 3.5mm plug of the amplifier. This should do the trick. You can experiment with resistance but it should be as high as possible to not interfere in sound quality, but if it be to big output won't swich or sound would chop on high volume.
Basic usb cable have four wires plus ground. While micro usb plug have five pins. This extra pin is used to tell device what cable is connected, hub earphones charger or pc. It can be done by two ways, in each cable this extra pin is shorted to diferent other pins. Or it's connected by resistor to ground or Vcc.
What i need to do is determine how it is in our devices and if it would be done make a cable what will allow to charge while using usb to other purposes.
I can also help with porting microusb-3.5mm cables from other devices to TG01, just what i need is this cable, it's schematic, connection route with insides picture or small donation to buy it for tests.
Or eventualy I can make solution how to do it yourself.
Right now I waiting for a pack with new empty microusb male and female plugs to do some tests.
If someone have some experience with this please share.
Also it would be great if someone will port me on to usb switch driver.
Feel free to talk to me on priv.
Thread will be updated...
Hi @patryk,
Welcome to the TG01 Forum.... especially on this particular topic - if you can find a way to get multiple function via the uUSB port simultaneously, that will be great
There have been various attempts at this before, but in practice the only route seems to be using Bluetoth for audio while either charging or using the port in host mode.
I did a piece on Brighthand a while ago on connecting an external hard drive; there have also been discussions on MoDaCo and later on XDA (down the Accessories thread.... one is here and I think there may be some earlier than that). There is a link in the XDA post to a Freescale Smiconductor chip schematic. This is supposed to be able to (externally) support multi-function usage - ntended to be used by 3rd Party manufacturers in eg. a car kit, but as yet I am not aware of any such accessories having been released. If/when available would be suitable for any of the modern crop of uUSB based evices, though I think many car makers have opted for Bluetooth connectivity instead of the older style fixed car kits with cables.
Acording to pdf from your link I'm right, its all about one resistor. It's entire possibly to do this.
Tomorrow morning tests...
Thanks
oh I cant wait so:
rid_f: >220 kOhms
rid_a: 122-126 kOhms <-- this is what we're interest in
rid_b: 67-69 kOhms
rid_c: 36-37 kOhms
rid_g: 1 kOhm
These res val has small tolerance and ar not typical.
rid_a resistance is used to switch to charge device from charger and use usb for earphones or hub!
earphones - yes, but headset - not sure I must check first where mic is connected
here it is Dummy cable schematic:
Here are some related illustrations:
Schematic of the uUSB standard audio accessory control:
View attachment 505996
Picture of the supplied Toshiba earphone adaptor pcb:
View attachment 505997
The mic is connected to pins 1 and 2 (White and bare Cu)
I have made up several 3.5mm audio adapters using Neutrik 3.5mm jacks with 10k resistors fitted from D+ and D- to 0V common:
View attachment 506008
This ensures it will switch to audio out when connecting to external speakers with or without a ground-loop isolator transformer where typically the external device will have too low an impedance for the TG01 to recognise.
Shorting out D+ (Pin 2) and D- (Pin 3) causes the TG01 to go into Charging mode.
An R from ID (Pin 4) to 0V (Pin 5) causes the TG01 to go into Host mode.
I check all of these Rid's and it seems they don't work on Tg01. No matter how i try there is working only charging or earphones never both same time.
As you say device can be forced to charge when resistor < 200 ohm is connected between D+ and D- and they are floating.
There also must be other way to do this by the driver of usb charging becouse pc link charges only when TG is on.
In TG mic an switch of headset are connected to ID pin. So this first schematic of yours is about Toshiba accesory ?
Technicaly charging while using audio out is possible becouse VBUS pin is free in headset.
I'll do some other tests tomorrow..
Hi!
Any news since February?
I will find answers on many questions by reading this document

It is a good document, but iunfortunately leaves many questions unanswerable.
In Section 6.4 it shows a schematic of an Accessory Charger Adapter which is essentially what we need to achieve simultaneous charging and audio out (or other functions). It does not however give enough detail to implement. I have previously identified a Freescale chip which has been designe dto do this job, but hae been unable to identify any source from which to obtain one. In essence this is aimed at the peripheral manufacturers' -who might wish to design and market eg. a hands free car kit to which you could connect a microUSB On The Go spec device. However so far as I can discover there are no manufactureres who have as yet brought any related device to market. If anyone happens to have found anything somewhere across the globe - please shout !

Kevin
Does anyone know if I purchased one of these can the Transformer then read memory cards or use other USB peripherals?
no one has tried yet, try it for us and find out!
I would if I had the tablet. If it does it would be a major plus.
Well we know for a fact that the 40 pin connector that is used to hook up the tablet to PC and charger through USB allows for USB host, we just don't know if it would be so simple that all we have to do is use a female to female converter.
I would think that it would work, because that's how you transfer files to the tablet. Not sure about peripherals though. If this does work it would easily make this better then any tablet.
if I can get myself to put down the money and if someone posts a link I'll try it.

I meant usb female to USB female since I don't have anything with microUSB just wanna test host.
Just bought http://www.amazon.com/gp/product/B000BSN4UY female to female adapter, I'll test USB host I guess
The tablet only has a micro, so I guess I don't understand why you would buy that item.

The tablet doesn't have a micro port, it has a proprietary 40 pin to USB male cable with a proprietary 40 pin socket. So you need atleast reg female to reg female to get host at the minimum.
Never mind just figured it out. You are going to use the micro usb cable that can with the tablet and hook up the female to female. Sorry.
I thought the tablet did have a micro usb host?
only ports are the proprietary connector used for hooking it up to the PC/charger/dock and mini HDMI out. But the proprietary connector supports USB host.
I've been looking for a cable to use in my car with my sII skyrocket for a week or so with no luck thus far. What I want is a single cable solution that plugs into the micro usb port on my phone and provides an aux out as well as usb out so I can charge and listen to my phone through my car. The usb would plug into a usb car charger and the aux out would obviously plug into the aux in on my stereo. I know it's possible to have one cable do this as I've seen docks that have this feature but I have yet to find a cable! I loved being able to easily charge and listen to my iphone with a single cable and hopefully someone knows where I can find one for my galaxy sII. Thank!
Does your car stereo have a regular 3.5 MM audio input? If so, just get a male to male audio cable and run that from your phone's headphone jack to the stereo.
I don't think there is such a cable because the Aux is an input that only take a signal from your device to the stereo, not the other way around. Usually those docks plug into the car lighter and connect to the radio using a specific radio station signal. Like burhanistan said, you should just buy a 3.5mm male to male cable like Retrak or Belkin and get a car lighter adapter for charging.
Yeah that's what I've been using but I would prefer to use a single cable to charge and play music. As you can see in these images the official samsung dock has a pass through auxiliary port with the only input being from the micro usb port so its definitely possible.
I might try and buy one of these and soldering in a micro usb cable to charge simultaneously but the skyrocket isnt listed under the compatible phones. Oh well my search continues...
Yea, sorry bud, the closest thing you're going to get is one of those Radio adapters that has a USB port on it, as well as the 3.5" male end.
I just checked on google for awhile and simply couldn't find anything. You can find these for the iPhone and I've used them, they rocked. Seems like the Skyrocket doesn't support audio out through the usb connector?

yeah would be nice..
Just bought one of these http://www.amazon.com/Samsung-Headset-Adapter-to3-5mm-Female/dp/B003W057FS/ref=pd_cp_cps_1
If it works with the skyrocket I'm going to solder in a usb cable as well to charge it at the same time. I'll let you guys know if it works next week.
i too would love something like this. i used the IMP adapter before on my iPOD it was great could charge and listen to music at the same time with only one connector coming out. seemed more clean as far as cabling went.
Well the adapter I bought does not work with my skyrocket... Oh well I guess I'll have to deal with a mess of cables for now
Is there a connector that will enable plugging the Micro USB receptor on the bottom of an HTC One to device with a male 30 Pin plug.
like iHome radios etc....

First off, please excuse the lack of links in this response. I am a newb and not allowed to post them.
Unfortunately there is no simple answer to your question, so we have to break it down into parts.
1) If you are looking to simply charge your device through the 30-pin connector then life is good - google "micro usb to 30 pin female" and pretty much whatever you find there should suit your charging needs
2) if you are looking to play audio over your iHome (which I'm sure you must be), then it gets a bit dicey.
Audio over usb on the HTC One was confirmed in this xda-developer post, but you will be more likely to have a working system if you use an audio jack to 30-pin converter. Google "android adapter for ihome" and near the top should be a GottaBeMobile link should have a review that will give you some ideas.
best of luck!
So here's what I want to do: remember when iPods (with clickwheels) were all the craze and everyone had a speaker dock for their iPod. You would stick your iPod on the dock and it would charge while it played music from speakers. I want to make a dock for my Pixel that sends out audio (3.5mm) and charges it at the same time. The idea is essentially to have a USB-C to to double USB-C splitter (basically impossible to find), into that I would plug a USB-C to 3.5mm adapter and a charger. Probably wouldn't be fast charging, and I'm okay with that.
Would such a thing work?
Is there a better way to do it? I have seen cables that are micro-USB on one side and 3.5mm and USB-A on the other side. That's what I'm going for.
I can't find anything that plugs into USB-C and has 2 USB-C ports on the other side. Do they exist?

The Pixel has both USB C port and 3.5mm headphone jack, no need to invent or look for a splitter.
You can use a standard USB C dock or a plain stand and plug in the charger and the 3.5mm cable.

The whole idea is to make something where I don't have to plug into the phone's 3.5mm jack, like an old iPod dock.
