Hi all,
I was wondering if anyone knew of a USB Y cable (with two male usb plugs converging into one female usb port) that could allow quick charge and data transfer so it could be used with Android auto? Both male usb plugs would need to be able to transfer data into the female usb port in order for this to work.

I guess this wouldn't work and might also damage the head unit, but I'm no engineer.
If I were adventurous enough to risk frying my head unit and/or phone, I would follow this
http://www.instructables.com/id/Add...-hub/step3/Cut-the-VCC-wire-of-the-USB-cable/
and connect the output of the quick charge car adapter instead of the external charger.
Then would cut the Vcc wire directed to the head unit.
I don't know if the main hub cable (the one which normally goes to the PC) has to go to the phone or the head unit: who's the host in Android Auto? I'm inclined to think it's the head unit, since the phone connects in mtp mode. So my first guess is main hub cable to head unit, quick charge adapter connected like in the article, then big usb to micro usb cable to phone.
Maybe voltage higher than 5V would fry the hub, and maybe Android Auto connection is so picky (and it's picky, you know) that the hub circuitry wouldn't allow it. Who knows.
Again I'm no engineer and I'm scared to try
But I would buy a safe device tested for this use case, 10/10 :laugh:

Use a usb y, but don't short the data pins to send it to high charge/current mode. You won't necessarily hurt the hu but you'll never connect to AA, the phone must detect the shorted pins to enter high charge mode. Which means the phone can't talk on the data wires. I find a 2a charger running at 1a plus the hu's usb keeps just ahead of the power usage.

Unfortunately, you can't have quick charge (2.0) and data transfer at the same time (at least with my Galaxy note 4). On a standard USB cable, you have 4 wires, two for data, two for power. On my GN4, the data pair communicate with the quick charger (I'm not sure exactly what the communication is, I remember reading somewhere it used the data pairs to communicate voltage, etc...).
Now, what I did do, was make my own data cable using 2 male type A adapters and connecting it all up to a a male microUSB end(Data pair is only connected to 1 of the type A male ends, I can't remember if I wired up the power in parallel). My AA head unit puts out less amps than my car charger, so even though I'm not getting quick charge speeds, I'm getting a bit more amps to charge with. So, one male end goes to my charger, one end goes to my head unit. I've been using it like this for over a year with no issues.
How much better is it than charging while connected to the AA head unit? Not sure. I'd rather have more amps than not enough.
Just buy a y. Cheaper and safer than self making.

Hi,
I want to clarify some aspects:
1) Qualcomm's Quick Charge doesn't work when the USB is in use for data.
2) Quick Charge requires a certified adapter (as it's an active function).
3) USB power can charge the device, however very slow... in fact with AA the device consumes battery when running.
So, my question is:
- Increasing the USB power current with an Y cable the device can be charged more quickly?
- And if this is true: the Y cable needs to block the current from the dta USB port of the car?
I like to comment these topics.

Sorry if this has been covered elsewhere; I couldn't find anything.
I'm looking into getting some spare chargers for my Tilt. I read at Pocket PC Techs that the device has a distinct "fast charge" mode, that uses a special pinout. Is this true?
If so, does the charger that comes with the Tilt use this fast charge mode? It seems to be just a standard mini-USB charger (data sheet here).
The link to Pocket PC Techs is actually to an adapter that they sell that is suppose to give you a fast charge with any USB charger. I'm wondering under what circumstances I'd have to use this.
Anyone know what the fast charge pinout is, and which third-party chargers use it?
Thanks.
ISTR reading something about pins 4 & 5 being tied together on some chargers -- should be very easy to test this.
I have not tested this but I suspect the pin out is the same as the Hermes:
http://www.tracyandmatt.co.uk/blogs/index.php/2006/09/10/htc_hermes_usb_connector_pin_config
The USB charging is done with different connections and at a different mA rating. The mains charger is 1000mA and is what I would call the normal charging system (but what the site you show, refers to as fast charge - but only by comparison to USB charging) This is just about standard for many sync/charge PDAs and not a special feature of the Kaiser.

I do notice a huge difference in speed comparing my old razor usb power adapter vs usb cable into my computer vs tilt power adapater so it prolly makes sense

Yep, the Razor adapter only delivers 500mA not 1000mA
Mike
Plus the razor charger does not have the pins 4-5 shorted, this is a HTC tweak that lets the phone know that it's on a charger vs std. USB power and it may in fact charge at a higher rate upon detecting this. I just know that my Hermes occasionally did strange things like turn off BT radio and other odd things when connecting/disconnecting from different chargers. Kaiser seems better at this.
For a couple of weeks now, I have been charging my Kaiser at work by using the adapter that came with my Audiovox SMT5600. It's been working fine. I cannot however determine if this charges any faster or slower than the Kaiser's adapter.
Slow Charging
So that would explain when I use GPS in the car with my old RAZR charger why the battery still drains. Darn, looks like I'll have to buy a new car charger.
USB Charging
are there any issues iwth battery drain or lif when charging with the USB cable connected to a computer?
Thanks,

Is there a specific USB charger.

I wouldn't think it would need to be tested. As per this page:
HTC has developed a range of accessories that are compatible across all HTC devices for consumer's ease of use. These include the BH M200 (Bluetooth headset), HS U110 (3.5 mm audio adapter and headset), and the HS S200 (HTC standard stereo wired headset) to enable effective communications on the move.

If the audio adapter and hard wired headset are compatible across all HTC devices (per HTC themselves), then that confirms that the pinout of the audio side is the same. And it's been mentioned earlier that the data side follows the mini-usb standard, which I can confirm: I'm using the usb cable from my camera to connect my Kaiser to my PC at home, while I use the supplied cable to connect it to my work PC.

I am experiencing a similar issue with an USB/car adapter and the USB cable that came with the Tilt.
Ran Google Maps yesterday with GPS on and when I got home my phone was almost empty. It was charging the whole time in the car though.
Does this mean I should look for another USB cable that is shorting those pins?
What about these adapters that plug into the phone and allow you to connect a USB cable for charging and a 3.5mm audio plug?

In answer to the original question, yes, pins 4 & 5 are shorted on the OEM charger that ships with the Tilts, thus enabling it to fast-charge the phone at currents greater than 500ma.
Hopefully this helps,

My problem is simple, i'm tethering my Wifi Nexus 10 to my Galaxy S3 and the S3 just doesn't have the staying power of the tablet and the AP is battery intensive.
I have considered:
Extended battery (unofficial) - don't want the bulk.
Extended battery (official) - not cost effective.
The other option would be usb otg and charger cable but I'd like a single cable if possible.
To make it clear - I'm looking for a double ended micro usb (B) cable.
If anyone knows of a reason this wouldn't work please do say
You could use this adapter with your original cable to see if it dies the job.
http://www.ebay.com/itm/Right-Angle...006572?pt=PDA_Accessories&hash=item27ccd180ac
I have the same setup (nexus10 and s3) let us know if it does work.
You could try monoprice.com. I get all of my cords and such from them.
eBuyer tend to be pretty good for this stuff.
Just FYI, I tried this using an OTG adapter and a standard USB-A to USB-B micro cable. Depending on which side I plug the OTG adapter into, the S3 charges the Nexus (when the adapter is plugged into the S3) or vice versa (when the adapter is plugged into the N10).
EDIT: It would be interesting to try though what would happen if one was to connect the four pins (VCC, D+, D-, GND) directly to one another, with the ID pin being left unconnected (since that is what a Micro-B to Micro-B cable would most likely do). My guess is that nothing will happen, since neither of the devices assumes a master/slave state and so it doesn't know that it should supply power to the other device. I guess I need to order some Micro-B plugs at Digi-Key and whip up a cable...
--fbrozovic
Can anyone enlighten me as to what the exact difference is between these two USB cables? Are they wired differently internally or is it just a difference in the quality of the copper used?
I have tried several USB "charging only" cables to connect my GT-N7000 to a PC. Some will data synch and allow file transfers but only in one direction and only some of the time, some of them won't connect at all ie are charge only.
At least one cable I bought from a leading IT store stated "USB Data/Synch" on the packaging but only works as a data/synch cable on a Windows XP netbook but NOT on my Windows 7 x 64 desktop PC. It won't connect for data synch at all on the desktop.
I have Samsung's USB drivers installed on both machines.
Only the original Samsung Data/Sych cable works reliably for both charging and data synching on both my PCs.
Can anyone tell me what's going on?
Thanks in advance
Trevor
All of those cables sound non-standard. A decent charging cable like the original Samsung one will likely have all 5 pins: power, data-, data+, ground and the other one which I can't remember. The power will be rated at at least an amp for charging and it should all work fine.
Power only cables may just have power and ground to keep costs down and some data cables are only rated at 500mA as that is to the USB spec.
I'd just get another Samsung cable, pretty cheap on play.com.

Hi all,
I know there have been other postings regarding this, but none have helped me solve my situation:
I have a "stock ROM" AT&T Note 2, and have tried two different Smart Dock units from Fry's. I get NO usable HDMI signal from either when connecting to my ASUS V228H monitor; the HDMI cable/monitor have been checked as working by connecting my DVD recorder up and successfully playing video content. USB connections to a wired keyboard and mouse worked well on unit #1, for some reason not on unit #2. There was no improvement when I rebooted the phone into safe mode. Lastly, the phone is correctly recognized by a PC when connecting via USB (MTP mode).
I'm ready to scrap the whole Smart Dock idea and instead buy an MHL-to-HDMI adapter and bluetooth keyboard/mouse combo, which I think can be found with total price just around that of the Smart Dock... unfortunately, I guess there's no "splitter" that could let me hook a hard drive up as well, like I could with the Smart Dock.
Does anyone have any ideas? I of course would hate to have to hard reset the phone, but might do it if there's really a good chance of it helping.
Final question: is it possible that the microUSB connector at the base of the phone could get damaged in such a way that USB to PC connections work, but MHL video does not?
Sent from my SAMSUNG-SGH-I317 using xda app-developers app
did you plug the dock into an original Samsung charger?
did you reboot?
mhl takes a lot of power, so you need to have the charger plugged in to make it work.
and the usb port can get stuck in a certain mode if you've used it too much without rebooting, a simple reboot will reset it.
I am using the new micro-USB to USB cord connected to the wall charger (FYI, plugged into a power-strip, not directly into a wall outlet, would that actually lead to MHL getting too litle power?). The phone was recently rebooted. I have typed this response using a USB-connected mouse, so at least that's working. HDMI is STILL not working.
Sent from my SAMSUNG-SGH-I317 using xda app-developers app
I'm guessing that unless it's specifically stated for the gn2, like the samsung dock, the microusb connector is using 5 pins instead of 11. That's the issue you'll have with mhl adapters, too: find an 11 pin, or buy the 5-> 11 adapter.
If it says compatible with the note (not note2) or evo, that's a pretty solid guarantee it's using 5 pins.
-----
I would love to help you, but help yourself first: ask a better question
http://www.catb.org/~esr/faqs/smart-questions.html
in this case the amount of pins is irrelevant. (edit: unless you didn't get a note 2 smart dock)
have you tried a different screen/TV and cable?
there are multiple versions of HDMI, and your cable or screen may be sufficient for an old DVD player but not a newer device.
Interesting that nowhere on the Smart Dock's box does it say "compatible with Note 2". But looking up the part # on the Samsung.com accessories site yields the following description:
Smart Dock Multimedia Hub
EDD-S20JWE
Compatibility: Galaxy Note II and Galaxy S4
As for HDMI protocols changing over time leading to incompatibilities... WTF? They don't need to create specification version numbers like USB to clue the user in? I will test your theory with an MHL to HDMI dedicated connector purchased today. If you're right, even this device won't work with my monitor...
This is going to sound like the annoying tech support people on the phone but... are you sure everything is plugged in tight?
I only ask because when I first got my smart dock I was getting picture but no sound with my hdmi cable and I was about to try a different cable but decided to try replugging everything first and voila...it started working!
It didn't make sense to me because it must be plugged in if it's working even a little but apparently either the phone wasn't docked all the way or more likely I hadn't pressed the hdmi cable in enough.
Would be nice if it's that simple in your case. Good luck!

Thank you for the suggestion. Yes, I had tested the Smart Dock's connections to make sure all were tight. No improvement.
I have given up on the Samsung Smart Dock for now. A "rig" that appears to be working is as follows:
1) Cirago MHL1000 MHL-to-HDMI adapter.
2) Mobile Phone->Voyage adapter (Micro 5 pin to 11 pin)
3) Comkia 3 foot HDMI cable.
4) ASUS VE228H monitor
5) HYPE Bluetooth Curve optical mouse
6) SMK-LINK Versapoint Bluetooth Slim Keyboard
You are definitely right about needing to check on the connection status of the various connectors. I periodically lose the HDMI video signal, which requires that I press the MHL adapter's plug tighter into the 5-to-11 pin connector. Yes, I also have the case off the Note II when attaching everything.
Sent from my SAMSUNG-SGH-I317 using xda app-developers app (using the rig above).
Okay, I'm noticing that the HDMI signal gets lost every 5-10 minutes and blacks out the monitor for 5-10 secs. I also have been having the issue of definitely less than 1080p output (not sure if even 720p) except for video player and Angry Birds Star Wars which do look good.
Is this a problem of the Cirago MHL1000 plus 5-> 11 pin converter, which would be solved if I just spent some more bucks on a Samsung HDTV cable with 11 pins? Will the Samsung MHL 2.0 cable for the S4 provide better output for a Note 2 than the Samsung S3/Note 2 cable?
Sent from my SAMSUNG-SGH-I317 using xda app-developers app
Okay, I sucked it up and bought the Samsung MHL 2.0 HDTV cable for the S4 and backward compatible with the Note 2. I think I've gotten things as good as it's going to get. Video out is stable and actually at higher resolution than using a Cirago cable and a 11 to 5-pin converter.
I unfortunately have no USB input capability for hard drive access. Is there any adapter to insert in the "circuit" to let me attach a HD to the Note 2 if its MicroUSB is already occupied by the MHL to HDMI cable?

hi
Hello, I have a problem when connecting a peripheral (mouse, keyboard, etc) the screen automatically flips and turns black, saying, which it is connected by hdmi too. that's not right.
otherwise it has explain, does not leave me connect the mouse and keyboard, because the s4 assumed that this also connected the hdmi.
Does anyone know of a USB cable that it capable of supporting AA and has USB-C on one end (for device) and double 3.1 on the other end (to vehicle)?
I have 2 USB ports in my vehicle. The input port for AA does not charge the phone sufficiently when is running and the other port does fast charging but doesn't allow AA to run.
Thanks very much!
Welcome to the never ending problem! No, it is not possible to do what you want to do, that is, to be connected to AA and to fast charge your phone from an other usb port or car charger. I tried everything, including powered usb hubs, nothing works, unfortunately.

Thought about that but I'm worried about overheating. I guess I might need to try it and find out?
Do not be worried of overheating, if the phone is connected to a usb cable and port and it detects charging, it will automatically disable the wireless charging.
The only way is to replace, if possible, car's charging circuit with a fast charging one.
