I decided to build my own dock today and wired up a micro USB plug to the official specs.

All I get is car mode but no charging.
Can anyone help on this?
Tried wiring the 5th pin to GND and Vcc but no deal
I need that pinout, too ^^
Don't know if you already know it, else for others searching for this: it seems that for some phones, it's neccesary to short the D+ and D- lines to activate charging without a computer.

What do you mean by shorting? Connect D+ and D- directly or do you have to connect them to GND?
connecting D+ and D- (not to ground) activate DC charging mode.
when standard wired it should work in USB charging mode.
DC mode is not good for a PC USB port which can only handle 500mA max so, be aware, your phone can suck up to 700mA and fry your port !

Hey guys I'm currently looking for a gadget where you basically plug the dock to the wall socket.
But instead of the dock being a pin connecter like for example this:

"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The dock has multiple USB plug-in (2 would be nice if not one is fine) So I can charge more than one usb rechargable device such as an iPod and the phone while using them.
Is there such device?
Thanks guys
EDIT: If there is none, I'm thinking of buying a portable battery charger. If anyone has recommendations of good ones that is durable and does the job please feel free to share.
something like this?

No, I'm looking for a thing where that USB part of the charger is a wire and leads to a "dock" where I can place on my desk but has 2 or one USB port.
I want something that will plug directly into a micro USB phone. I'm aware of the multitudes of this design:

"lightbox_toggle_sidebar": "Toggle sidebar"
}
I had one, thought it was garbage, it made an irritating noise both charging and discharging, its connection was hit and miss as bumping it might disconnect it, and eventually less than 6 months later it stopped working. It was advertised as a 2800mAh but its charge was extremely poor. Yet, those are the only type of chargers I can find, all from various companies using the exact same design.
The Motorola P790 is ideally the type of thing I'm looking for, it even comes with a slide out USB so it can't get damaged, but it's no good since it's a mini USB and would require packing around cords:
I'm not looking for a mega charger, one charge or so is fine as I'm not trying to carry around more than a second phones weight in a charger. I find it extremely odd that with so many phones out there, there hasn't been a decent micro USB charger without cords that I can find.
Does anyone have any suggestions?
Forget about my other topic It made no sense.
If you had a cable with a micro usb connector at one end and two micro usb plugs at the other that is how you would get a hdtv adaptor and usb to work simultaneously.
There are none of these anywhere and nobody has built one so someone with skills in electronics they could make one.
Seems simple to me.
Maybe Samsung will come up with an adaptor like this.

}
Why?
It seems plausible to me as the two micro usb plugs would join to the connector going into your phone, the hdtv adaptor would still have a charge as you would be charging it through the adaptor and the otg cable would connect up to the other micro usb plug.

READ THE OTHER THREADS. so a search for MHL+OTG.
I didn't say that MHL+OTG would not work, i said his way of doing won't work, as is outlined in the other threads.
there are MANY threads where the exact same idea comes up, and in the end: nope the hardware each of you want to use doesn't do what you are assuming it does.

No, it does not give any notification if nothing is attached to the cable.

He's talking about when nothing is connected to the adapter. I does not give a notification as it shouldn't. Just like if you connect a usb cable to a computer with nothing attached.

And I am saying I always DO get a notification when i plug in my otg connector . even with no device connected . ..
My OTG cable (monoprice brand) gives a "USB Connector Connected" notification when you attach it with nothing connected.
It also works fine.
So, like if I get no notification? Is it working properly?
