[Q] New Nexus Dock + OTG Cable? - Nexus 7 Accessories

Not sure if this has already been discussed/discovered, but will it be possible to use the new Nexus dock "and" an OTG cable at the same time? It seems feasible given that the dock charges the device using the pin connectors which frees up the USB port.
One possible problem is that the dock also acts as a passthrough for data/audio so there may be a problem with the tablet trying to reconcile both sources trying to have simultaneous access.
I ask because it would be nice to be able to charge my Nexus 7 and utilize an OTG cable (for storage drives and game controllers) at the same time. I know there is an OTG Y-cable solution, but that involves rooting the tablet.
Has anyone already explored the possibilities of this combination?

I read somewhere else that while docked, the device doesn't react to an OTG cable. This is just what I've heard, haven't seen it confirmed.
This guy did something similar, and the results are evident: Dock point is useless! Charge and OTG can not be carried out simultaneously!

Would be nice to know, if Timurs kernel, which allows charging and multiple USB would solve this. Have no dock, so I can not check. What I would like to have is something like the magnetic pogo charger which is annonced for Nexus 10.

[Q] And USB adapters for the DS7 yet? So we can hook up controllers etc.

Just wondering, since some of the newer tablets let you hook up mini usb devices to it and so. Was wondering if there had been any adapters yet or so for us streak 7 users? Would be cool to get a wired controller hooked up and so.
You would need an OTG cable to do that, as dell doesnt make any you will have to make your own or use the HDMI dock.
Well I have the HDMI Dock, so I could use the dock then insert the usb device to that? Was thinking about getting that Logitech F710 with that usb dongle, heard it had support for android. What else would I need? Or hows that work fully.
As for the non dock part, has anyone made a cable yet to work?
if your device had a usb-a connector you have no choice then but to make a cable.
the sixaxis/ds3 uses a mini usb connector and might work though usb,
I know it and the wiimote will work over bt, with the wiimote being the easier to pair one.
Well I have the wiimote working fine, Issue there is.. Yea.. Battery drain on that remote. So figured maybe getting a adapter. I guess I need a USB to Mini micro usb? (The new style mini usb thing.. man I miss the old big RAZR size ones) How many of you have used a HID device or so on android or the streak 7?
you'd need to splice together the dock connector to preferably a USB-A female port, it'd be the most useful as you'd have a cable that could accept anything, but it'd mean you'd always need a minimum of 2 cables.
You'd also have to dissemble to dock connector itself i believe as the OTG pins are different from what's wired in the normal sync/charge cables, you cant simply cut the cable and rewire it, you'd prob have to cut the dock connector open and resolder
If you made a dock to micro usb connector it'd only accept devices that have a micro usb port on it.
Keep in mind usb mode means that the controller would be drawing power from the device itself, while controllers dont draw that much, it's still something to point out
Wouldnt this be all I need?
http://www.amazon.com/USB-Female-Mini-Male-Adapter/dp/B0016RNX2I/ref=pd_sbs_e_4
Would take the normal size usb dongle or cord, fits into the USB slot of the dock itself.
I havnt actually tried it but it sounds like that should work, i know that port is designed for otg connections so i'd assume it'd take care of the hard work.
When on 2.2.2 Did I need a special program for this to work? I know 3.x had native support. Just wondering. =) (Or can any game/emulator with key remapping auto detect)
if it's anything like the hoops needed for the s5 on 2.2.x yes, unless dell included their own code stuff to make it work, then i'm not sure.
I've never attached a controller to anything, wired or not so I can only say that much
Wonder what the app would be called or so, anyone know? I mean I ordered the part, should be here in a few days, then I can report any tests I have with a Rumblepad 2.
Ok tested it out, So far nada. Dont know if its even supposed to work.
Has anyone here hooked a wired controller up to their android? Running Honeycomb now too.
I know people talk about the F710, which I wonder if that works cause its battery powered?
So what's the verdict guys? Can a controller or other USB device be connected to the mini USB port on the docking station and work? If not, will it work if you plug in a mini USB OTG cable (like this one http://www.ebay.com/itm/Mini-USB-Re...757?pt=LH_DefaultDomain_0&hash=item3a6edf5335) into the docking station and then plug the controller into the OTG cable?
So far my verdict is nada.. dont think its supplying power to the usb ports. Now its been said that adapter based ones may work, something where controller is powered by batteries. Tho again. No one ever gives a real confirm.
My next area to branch out is http://www.onlive.com/controller 50$ but you can use a adapter for the pc. However it also works with bluetooth, something that the tablet DOES support and no adapter needed. Since I have the onlive app, least it will work 100% for THAT. Once my tax money comes in, Ill order the controller and see if it can work on emulators and so too. least then we will have 1 solid answer that has some good use. (Since honestly, onlive on the tablet really isnt bad at all!)
Why not bluetooth your ps3 controller though the sixaxis app on the market thats what I've done works great

I have used my Wii remote that way

To answer both. If I am not mistaken. PS3 controllers have to be "paired". Which means when you wanna play PS3 or Tablet.. got to re-pair them all the time, correct?
Wii-Motes I know you dont have to re-pair them. However.. one thing I hate... that to use the classic controller.. you need to have the Wiimote laying around somewhere.. then the cable for classic. Seems bulky for normal use.
Both controllers all are battery too. Would be nice for wired solutions. If I do anything wireless, I may as well get that Onlive controller with BT support.
If you have a sixaxis/DS3 dedicated to non-ps3 use: you only have to re-pair it every time you want to use it on a different device.
The sixaxis/ds3 do work in usb mode, at least on pcs. I dont recall if there's a solution to use it in usb mode on android (though i'd imagine it should, as usb mode is trivial to enable)
If you only have a single device to use it with, you only ever need to pair it once and then you're done.
Well, I finally went and tried hooking up a usb hub to my S7, and my results were absolute failures.
I bought an OTG <-> dell 30 pin a while back and a standard OTG <-> dock cable.
I dont have a baseline as I dont know offhand which kernels are specifically tested to work.
It seems to enable the hub (by enable I mean it powers up on detection of a host, it's wall powered)
on my S5 with ICS/Phoenix kernal (which is known to support usb hosting), but nada on my S7 with ICS B4/mod and stock 514.
Can anyone explicitly confirm that the b4 and stock kernals work with host?
I'm pretty sure nothing is happening on either of those, and as it works fine on my S7 it's definitely not bad cables/hardware.
Edit: at least the S5 is even capable of powering the hub itself, and with a dock it can charge at the same time. If it wernt for the terrible HDMI out on it, it would be a full on android pc with the dock.
The S7 on the other hand: I still cant get anything, remotely powered or self powered: it gives no response
I can tell you, yes, ICS kernel does have otg drivers but may not provide power to those devices.

Split the micro USB for charging and USB OTG

Hello,
I want to do some stuff at the same time with my phone.
Watching a movie from an usb stick while charging the phone.
So, I've bought this HDMI converter
When you plug this into the phone you can plug in your charger or USB OTG adapter in the usb port on the HDMI converter.
But i can't find any splitter cable on the internet or ebay so i can charge my phone and connect my usb stick at the same time.
I wonder if this is even possible. It is possible to charge the phone when HDMI converter is connected and it is also possible to connect my USB stick to the HDMI converter.
Anyone ever tried this or has found a simple micro usb splitter cable or normal usb splitter cable?
You can't connect a normal USB Hub because i can't send power back to my phone through the hub.
Thanks :good:
Sorry I can't help with your splitter request.
However I'd be really interested in knowing if those two items work fine with the Note 2?
Sent from my Nexus One using xda app-developers app
so the i know it isnt possible with the 5 pin mhl adapter (the old one thats not compatible with this phone)
I wonder if the 11pn version does allow this. I know the cables dont exist for what you are looking to do, there is a galaxy note smart dock 2 that seems to allow hdmi and 3 usb ports, if they allow it at the same time then it would be at least possible.
it must be. did you try the smart dock?
http://forum.xda-developers.com/showthread.php?t=1953061&page=2
I've ordered one and i will see how it will perform. smart dock is nice but pricey i'd like one for home and work!
Bought this one http://goo.gl/6OiGx and as it is listed compatible with the NOte 2 and the Galaxy S3 i was hoping it would work with the Note 2 as well - nope: only power OR OTG, not both.

Old thread... at least on my GS3 I have found that the ability to charge and use USB OTG at the same time is kernal specific. Anyone ever find one that works on Note 2?

Connecting USB keyboard problems

Hi,
I ordered a case for a Nexus 7 that has a buit-in USB keyboard. I thought that connecting it would be a simple thing, but I'm having troubles. I bought a 2-sided female USB adapter to link the keyboard and the Nexus' charging cable. That doesn't work.
With some troubleshooting, I came to the conclusion that the keyboard does work, and that the trouble lies with the connection. A little research led to find that the Nexus doesn't have a micro-USB port like I thought it did, but a OTG port.
I'd like to know if something like this (female USB - OTG dongle):
http://www.ebay.ca/itm/EEEKit-for-Google-Nexus-7-2-x-Micro-USB-Host-OTG-Adapter-Converter-Cable-USB-2-0-/400367750285?pt=US_Tablet_eReader_Chargers_Sync_Cables&hash=item5d37c70c8d
would do the trick before ordering it? Or if there is another proper way to set up the USB keyboard?
Thanks!

This cable will fix the connection issue and you should be good to go!

Usb otg not working

Phone happily charges through usb otg hub. No drives show up in xplore. How I get this to function correctly?
Also not functioning is my n64-usb adaptor.
I look forward to the day my xt894 (and an eventual, worthy, successor) can replace desktop computers for more tasks

It seems to be a common belief that the Droid 4 supports USB OTG. And it's fair, really, given how many sources say that it does.
It doesn't. It supports USB Host; it can serve as a device host, but can't actually supply power itself. You'll need a powered USB hub between your devices and the phone for it to work. On top of that, you'll need an OTG adapter that the phone wants to work with (apparently it's fairly picky and won't work with all of them). And, it may or may not work under Lollipop, if you're using that.
I'd expect an OTG hub to work, since one would assume it's just a miniaturized hub made to run off a microUSB charger, but apparently not. Probably wired differently than a USB hub.
Why does the phone support Host but not OTG? I would imagine because they wanted to encourage sales of their Lapdock, which itself has one or two USB ports.

USB Audio

I'm thinking about using an Amazon Fire 7 inch tablet as a car radio dashboard install, but before I commit to buying one, I can't seem to find any conclusive answers on a few things.
Firstly, does the fire output USB audio so I can use a USB dac?
And if so, is it possible to use a Y split cable for USB audio and charging at the same time?
Any info would be greatly appreciated.

I can confidently say this Fire like most other Amazon devices will not support charging while the USB port is being used for any other function. Can't speak to USB audio out (suspect not) as most go with Bluetooth.

It does seem to be a difficult feature to find on Android tablets.
According to Wikipedia, it's a simple implementation of a USB otg cable that should allow charging on any usb otg device.
USB Otg Wiki
The major problem (presuming the cable does work and usb audio is possible) is that the kernel needs to be able to enable USB otg at the same time as charging.

Yep. The stock kernel on most consumer devices don't have robust OTG support as the most commonly used gizmo is a flash drive. I was able to get a OTG GPS receiver to work but it wasn't plug-n-play by any means. Charging didn't work in that context...although I didn't fiddle with it much.
I've been working on a kinda similar project, I just haven't had time. I'm trying to use my fire as an octoprint server, which is a program that monitors and controls 3d printers. The problem is that it requires usb to be connected to the printer, while also staying powered on. What I'm going to try is remove the battery, step down 12v from the printer to 3.7v and just hack it onto where the battery would connect to the pcb. I'm not sure what the different pins on the battery connector are though, so I'll have to test those. Otherwise, it should work.
