How to broadcast music over USB cable

Hiya all - I have one of those car chargers/fm transmitters that work with all USB cables. I used to use it for an iPhone. With iphone, when you plug the device, the ipod would automatically send the music over the USB cable to the actual charger/transmitter, thus allowing me to listen to the music via car stereo speakers. Is it possible to do the same with Nexus One (trying just straight on didn't do the trick )
Thnx

USB does not have contacts/wires to transmit audio. There is only power and data. You are confused

Well that might be true, but it totally works with iPhone

Most likely because it's an iPhone accessory and the iPhone has drivers for it which android doesn't.

If you get/have a head unit that has a USB port you can use your phoene and charge it if you mount the phone as a USBdevice.... ive done that with my G1 and it works... Other than that i dont know of any device for the N1 or any usb type device that does that....

Yes, you are confused. Normal USB doesn't transmit audio.
You want one of these

I plug my phone into my car (if your car has a standard 3.5mm aux port like mine), and play music perfectly fine. 0 software required.

USB is better, but NOT through FM FM is rubbish compared to jack cable.

I think he is talking about where the head just plays whatever files you have though the usb.
I don't have a unit that will read a usb mass storage.
Has anyone tried the N1 with such a system? (I'm guessing it might with it mounted)
LGU

If you have a car radio that can read from a usb storage device (e.g. a flash drive): Plug in the Nexus One and "Select to copy files to/from your computer".
Calling that "playing over usb" is a complete misnomer, though. The radio will just read the mp3 files over a usb data connection.

I think the confusion was with the SD adapter. It said "8.9 only" on Samsung CTIA slide. Hopefully they'll have one.

Anyone else think it's a bit of a con to release these all as separate adapters (i.e. if you want HDMI then that's an adapter, USB is another adapter, SD card slot is another adapter). I think Samsung could have put all those connections into a single adapter. Also, it's weird how the HDMi adapter has a little bit of cable to give some flex in the connection where as the USB adapter is just a single block.

Considering how big these adapters are, shame they couldn't put USB and SD or USB and HDMI or all three on a single adapter.
Even the media port doesn't appear to have HDMI out it, looks like it has another 30 pin port on the back and you have to buy the HDMI adapter for that.
All these adapters, all being sold separately is gonna get quite pricey too. Even Apple was compassionate enough to sell the USB and SD adapter in a single kit for $30 (saving $10 over buying each separately for $20).
PS. Though I imagine some third party might save us and come up with some adapter that combines multiple things together. They've done it with the iPad adapters.

Ugh these accessories are such a rip off. $19.99 for the damned additional data cable?! The hdmi cable port is also $29.99, just absolutely ridiculous. I'll prob eventually snag one regardless... :-/

Most definitely. This tablet is going to have so much aftermarket accessory support, we won't know where to begin.

With the exception of jump drives, most USB devices have their own cable.

Does anyone know if the HDMI converter works with the 7" Tab?

You guys are lucky to see accessories, the UK mob don't even have a clue about the 10.1

$40 for HDMI!?! Are they ****ing serious?! Who do they think they are? Apple?!

Possible to use this adapter for usb-keyboard use on the note?

Is it possible to use this cheap 5-pin Micro-USB, type B - male to 4 pin USB typ A - female adapter to plug in a usb-keyboard to the note?
Or is it something special about these OTG-cables?
Please see the attached file.

I have tried a simple adaptor and it did not work - there are very similar looking adaptors that are OTG though.
Personally, I prefer to use a mini Bluetooth keyboard with integral "mouse" touchpad or an OTG cable to connect a similar USB keyboard rather than an OTG adaptor as I worry that I may lever the adaptor by catching it and cause damage by the straining the micro USB socket in the Note.
When you plug in an OTG adaptor or cable, the Note comes up with the message "USB connector connected" - a plain adaptor does not cause a message.
The picture below shows, from top to bottom, OTG USB adaptor connector, OTG USB adaptor lead, Wireless mini keyboard with mouse "touchpad", Bluetooth mini keyboard with mouse "touchpad".
Both mini keyboards came with wireless or bluetooth receivers which do not work with the Note as, I assume, they need "Windows" type drivers. The Wireless one cannot therefore be used with the Note (even though it also has a mini USB connection - probably only for charging use) whereas the Bluetooth one does work can as it connects using the inbuilt Android/Note bluetooth rather than using the supplied mini USB bluetooth receiver.
Hope this helps!

USB-OTG (they're all the same) works perfectly with some USB keyboards and mouses but not with all of them. I'm using Genius mouse and Microsoft Wired 200 keyboard.

Thanks, i'll try it. If it works it works
btw, neat bluetooth keyboard/mouse you got there!

I have a mini-wireless USB keyboard/trackpad from Kogan that looks closer to the mini-Bluetooth one in the 2nd post, and that works fine with my usb2Go adaptor and the Note. I know both look similar, but the button configuration under the trackpad on mine is the same as the Bluetooth one.
I like the idea of the bluetooth one mind you!

Dave

Thanks for that info, very useful. I'm considering getting one, can you advise where you got yours (a link would be great, if not, a manufacturer name and/or part number would do ... worst case can you advise approx price & dimensions?)

Although I have a USB one I bought from Kogan, this thread made me aware that there were now bluetooth ones too, so I've just ordered this one from Ebay:
http://www.ebay.co.uk/itm/Rii-Mini-i6-Bluetooth-IR-Keyboard-Touchpad-2-1-UK-Latest-Version-2011-/250901297139?pt=UK_Computing_ComputerComponents_KeyboardsMice&hash=item3a6ae1f7f3#ht_2215wt_905
It seems to be a slightly later design/model than the one shown in the 2nd post here, but you can find that too if you search ebay with the term "mini bluetooth keyboard rii".
Regards,
Dave

looks good - the universal learning IR remote is a nice add-on too. Let us know how it performs when you get it ...
meantime, I see you've got a wireless USB k/b already working via USB OTG. I'm awaiting my OTG adaptor so I can try that out with my existing (compact, but not mini) wireless k/b with optical trackball. Not sure how much current the Note can supply for OTG usage but I guess I can just use a powered hub if required?

[Q] hacking docks to provide audio, hdmi or sync (MHL and stuff)

I've spent some time searching looking for something on the subject, but haven't found anything that seems to cover it (does that make me special (I did laugh at the video), but enough off topic).
so I specifically have the Samsung Galaxy Note. though I realise in a lot of ways its really just a big S2 in most regards. and I suspect several other devises that would be comparible.
I'm currentlty using a dual charging dock station which I bought cheaply of amazon, and that gives me sync and power. having looked inside the case there loads of spare room in there. and so I'm wondering about playing around with the MHL adapter and ideally something like the audio out with the official samsung dock.
from what research I've done the note senses what type of dock its in by the resistance on pins 4 and 5. now even with my basic electrical skills it seems rather easy to put in a 3 way switch to select between these
obviously the guts for the HDMI out would be from a MHL adapter, and that should be possible to power through the standard connectors on the current dock. but what I cant seem to find would be the associated parts for the audio (dont want to buy the official samsung dock just to rip it apart) (one thread on here about stripping the cable back to power and then the 3 inner wires were left, right and ground, but didn't see any evidence of that method working)
the audio aspect has another relevence for me, as I'm also wondering about a note dock/speaker set up (cheap 2.1 speakers, rehouse the sub to a case that incorperates the mUSB connector, audio components, and power, so that other than speaker cables and one power cable that'd be it (currently use a Sony NWA-3000 plugged into old pc speakers for such night time listening)
so thoughts and advise (specifically on the audio aspect)

Thatz pretty impressive. I too have that sony dock. I think about modification of it so that i can plug in my hd2 in it. Ie just to put an micro usb plug out from it, so that i can charge my phone while i plug in 3.5mm jack from the sony dock.
Thatz all about mine.. now letz look into ur case.
Cant u try out 3.5 mm jack for audio o/p?
Or else u can check out pinouts.ru for pin config of hdmi, coz, u r going to take out hdmi from sg note any way. So u can rip the cable apart and take out audio and video wires, connect the video cables to tv and audio to dock/ amp.
But i suggest that 3.5 jack will be the easier way.

So I don't know about it, I would say that it really isn't that feasible. Besides putting a different resistance you would also need to route the data lines to a different location to the MHL to HMDI converter.
If you were to do the video or USB you couldn't do audio. From what I understand there is a IC that looks at the resistance on the ID pin and puts the audio signals on the data lines. Once again you run into the same problem that you have with the video adapter, routing the data lines.

got a brief schematic for layout. I'm buying some cheap bits now (MHL adapter, USB soundcard, USB OTG cable)
first a few explanations on the schematic, software I used didn't have many switches on it, so plan to use a 4 pole double throw like this rather than the 2 sets of 2p2t shown in the diagram
secondly, not sure if I need to short pins 4&5 for OTG, still reading stuff

Yap, u got it.. but also provide external power supply of exactly 5v in usb host mode, so as to power slave devices.

guyz, i wanna ask something, in order to use MHL adapter, does the phone need to support MHL protocol? and the protocol resides in the hardware part or software part of the phone?

The MHL lives in the phones hardware is the simplest. If you find the Galaxy S2 hack pack it will show you a block diagram of how the MHL exists there.

as giritrobbins said it is hardware based.
it shares the microUSB connector, but uses an entirely different signalling. hence why it has to be separated out. otherwise a hub would do every thing I'm trying to do here

Hi, folks just thought I would ask how this project is going ? It's really quite fascinating.

Pin 5 (ground) can be carried through to everything.
OTG requires ID (pin4) to be connected to Gnd (pin 5).
In the diagram above S2 is not really needed.
If you want to switch electronically, there are lots of ICs for doing that.
Here is one picked entirely at random: http://www.fairchildsemi.com/ds/FS/FSA3000.pdf
MHL will be the trouble spot, USB is much more forgiving.

I've seen docks like the one you're tying to build on eBay with built in MHL; is that what you're after?

Well, if you look at the service manuals, they have lots of details about where stuff is coming from.
The MHL is all digital coming from the HDMI chip. There is however audio, which you'd need to enable in the snd driver as
a RX enabled, and also it looks like the I2S would have to set up the microUSB chip to export the analog
audio through the USB port.
At least in the case of the 8960 systems (Galaxy S3, OneX?) this is the USB driver setup.
The audio is coming directly from the qualcomm codec chip and you'd have to enable it with
the tabla stuff, then the USB, but it might be programmed to sense USB headset.
---------- Post added at 10:33 PM ---------- Previous post was at 10:10 PM ----------
Basically, if you want analog output only, you need to use the MUS_I2C to tell the Fairchild USB analog mux to enable the
audio lines. Then you would need an audio amp because the codec output can only make it to the analog mux
and I'm not sure what kind of buffering is on the uUSB chip. But if you are going this route, you might as well use
the headphone jack. It's not digital unless you use the MHL.

Two things to bear in mind when demultiplexing the USB connector:
The analog audio out ("CarKit") has a signal that goes below ground.
Some electronic demultiplexors might not handle that.
The MHL signal goes into the Gigahertz.
Don't try switching that with a Radio Shack relay or connecting using loose wires.
MHL uses the two data lines for TMDS data and the ID pin for CBUS.

i9505 MHL with CM12 and other Lollipop roms (no TW)

Hi guys,
can anyone help me get my MHL connection working with i9505 running CM12?
I bought a new MHL adapter (one side microUSB - charging port - HDMI out + reduction for micorUSB for S3) then I connected to my Samsung TV (older model like 4 years) and ... nothing happened on both sides. The only thing I saw was a phone charging from the adapter (because of external charger). Do I need to modify something, or is it my TV not supporting?
Appreciate help

Hi!
I've got some information, I think I can help you.
First is support for HDMI in CM12, i checked it on SaberMod CM12 and it's works. I dont know what with another CM12, CM11, MIUI build, TW rom support that but Live Demo Unit soft (S4 with Retail Mode and without GSM) no.
Second, what type of MHL you have?
- MHL1 with 5-pin cable - this is for S2, Note (1) Glalaxy Nexus and some another. Probably incompatible.
- MHL1 with 11-pin cable - for S3, Note 2, S4 and Note 3 work good
If you have MHL with 11-pin cable and it's not working you may use another reduction for micorUSB, maybe your is damaged or MHL is damaged.

thanks for answer!!!
The adapter is new and is for the newer models - Note 2,3 S3,4 - I tried connecting from microUSB and also with the reduction for S3 (different shape of a connector a little) - but still no go. TV saying no signal. Let's assume my connector is not broken (everything else works)
I am on AntaresOne's CM12 optimized. so I will try to ask in the thread you posted - maybe ther are some modification of the ROM inside which allows MHL.

and also with the reduction for S3 (different shape of a connector a little)

What you mean? S4 like S3 have the same microUSB port, can't be another shape of connector. The best way it to show your MHL cable. I have that:
