Has anybody reverse-engineered the pins in the docking port? Would be interesting to create some custom accessories for that...
It's an I2C serial connection, from what I've read, so you're not going to get much more than what already exists: keyboards.
Edit: And this can be confirmed in Device Manager.

Anyone know of a micro USB to RS232 Serial adapter?
or for that matter if the Epic can be used in USB Host mode?
My goal, is the be able to use my Epic 4G to run a terminal link to some control boards using ZiLog Z8F processors, I work a job as a field technician on energy management controls. Currently I lug a net book around to flash and terminal into the controls.
If I could do the same without having to drag my net book with the rest of my tools, that would be incredibly awesome for me, I'm always trying to find ways to minimalism the amount of gear I have to carry from my truck to the boiler room.
Thanks
The only thing I have seen that comes close to what you are asking is this thread in the dev section: http://forum.xda-developers.com/showthread.php?t=833373
I dont have any information other than the link, but thought I would at least point it out.
Thanks, at least now I know where to ask questions and pick peoples brains!
If you could find the appropriate cord and drive it from your epic.
I used this back in the day (not from a phone) when I lacked a RS232 port on my devices...
I have seen adapters that would likely drop the usb to micro easily enough but.. thats the least of the difficulty

really not sure if it could even make this work from an epic, lacking any readily available drivers though.

If you can relax your requirement for USB, then use IOGear RS-232 Bluetooth Serial Adapter (model GBS301). I use this along with the app BlueTerm on the market. Works for all of my RS232 needs.

Might be worth a shot. I didn't see anything looking quick, but I know they have lots of different options and if all else fails custom build components as well.
A USB serial adapter won't work with the stock rom (or any custom rom not implementing usb host/otg).
In theory, it's possible to repurpose the usb port's pins as gnd, txd, rxd, and a resistor of specific value that tells the phone to electrically route their signals to pins on the SOC chip with txd & rxd functions at nonstandard voltage levels, but I'm not aware of anyone who's literally gotten it to work on the Epic, yet.
Note that serial via this method has *nothing* to do with usb; it's just temporarily repurposing the pins & connector for serial use.

Does anyone know if the sensation has audio out on the usb port? If so, which pins is it on.
Looking to butcher a dock to make use of it if it does, to save me having to connect the 3.5mm jack and usb connector at night.
Usually, the pins are 'multi-use'.
So to get them to be 'Audio', you'd probably need to have a certain resistance across some pins, which would make it 'sense' that you have an audio device connected.
You could try a micro-usb audio adapter from, say, a Toshiba TG01 (I had one of these) and try it. (The TG01 also had USB Host adaptor as well!)
You might find there's an official lead for it, or it might just not be a feature that's available.
Until we get a service manual for the Pyramid, or you find a lead and test it, we're going to have no luck.
ICS is rumored to have support for USB Host, that should open up a world of possibilities, such as this.. not sure if this is possible at the moment, but I would wager that it's not.
Hi. I've just recently tried out an app from the market that would let me control emulators and some games with a Wii remote, but it wasn't compatible with my G2x. However, I stumbled upon what is most commonly known as "OTG" cable, but discovered they were worthless for the G2x as of now because 2.3 doesn't have USB hosting.
What I wanted to know is, number one, will the G2x have USB hosting when the official 4.0 update comes out, or is it missing some special hardware needed for that? And number two, is there any risks in just getting a cheap MicroUSB to Female USB cable from a trusted seller? Like, can it damage any internal parts because of different voltages between devices or something like that? Or is the worst thing that can happen is the cable simply not working?
I'd really appreciate an answer on this one, because USB hosting seems to open up a lot of possibilities with our devices.
The short answer as of right now is NO there aren't any common ways to enable USB Host. With that said, can the Tegra2 chip in the G2x support host mode?...yes. Will it require a custom kernel?...yes. So basically your phone needs to be rooted to say the least and a kernel framework to enable and support it. I'm actually looking into this as we speak but it's looking like it'll be a while.
As for the cable... no most generic micro-USB cable won't work as is. The OTG cables have either a 'grounded' 4th pin or a disconnected 4th in some usb host modes. But either way you either need an OTG cable or if you search online you can find several ways to splice and solder back generic USB.
I have been looking for a while, but there doesn't seem to a custom kernel that supports USB Host mode. I already have USB OTG adapter (mini Male to 4 pin USB female) + arduino board etc.. So are there any custom kernels out there?

Nothing had really changed on this front, if you want to use Android as an ardi interface, I'd suggest you grab a cheapo phone that supports it out of the box.

Any update on this? Seems ICS/JB roms are out now... any strides in getting OTG to work? I'm looking to make a G2x into a dedicated TV gamer unit to replace my MK808 and forgot about OTG for my air mouse. I have a Bluetooth mouse to get me by but the airmouse was awesome.
I guess I can look for a Bluetooth airmouse as a last resort.

No OTG happiness for the G2X with any ROM and/or Kernel. There is a board from Sparkfun which provides an interface that enables a non-OTG phone to work like one for interfacing to Arduino, etc.

Can't seem to find a definitive answer as to whether the phone can detect a USB connector with appropriate resistor added to signal dock mode (desktop vs car).
Apparently the stock ROM doesn't have support, but perhaps CM9, etc may?
Can someone with first hand knowledge comment?
Thanks!

I don't have a dock, but CM10 has a specific settings item for Dock Options. I'd assume this means it works...
I think that might be generic.
I'm not sure if the hardware detects a resistor between pins 4 & 5 on the USB cable to signal if its in desktop dock vs car dock.
We use our phones as alarm clocks too, so not having that feature pretty much kills the phone for us.
Finding something like the N1 that has good docking abilities that isn't huge is tough now a days. (Too bad there are few phones with POGO pins, that makes the experience awesome)
I'm looking for the pinout to make a dev cable or if someone is selling one please let me know.
i'm looking also for pinout of this cable
wondering whether i can use uc-e6 cable with pinout below?
http://pinoutguide.com/DigitalCameras/nikon_uc-e6_pinout.shtml
Looking for the pinout of the dev cable as well... I have one of these and plan to start building LOS for it. I came up with the UC E6 as well but according to Wikipedia it's "non-USB" so makes me wonder if they're using a different pinout.
it has been a while since this got asked but here is the actual pinout for the connector https://github.com/Stricted/adt1-pinout
you can find the plugs on ebay with the search term "Mini USB 8Pin"
enjoy, have fun
