[Q] usb host - what adapter to get? - Samsung Galaxy Nexus

I'm a bit lost with this usb-a and usb-b stuff.
Should I get USB-A to USB-B Micro or USB-A to USB-A Micro?
I want to use this phone as host for various DSLR's. I'm rooted and have all the software needed for this.

what you need is a male micro USB to female USB A.

So it doesn't matter if the micro male is a or b? I get the regular female side...

You need an OTG Micro-USB B to Standard-A receptacle.

Could you share what exactly you want to so with dslr's?
Im a photographer and would love to use my Gnex as an alternative to Nikon's 700 euro WT-4 wireless adapter!

If you've got a spare DSLR you can send it to Chainfire so he can write code for the Nikon variant of DSLR Controller!

Excellent! Thank you, very much.
The dslr controller should work cause I use 5D mark II. But I'm more interested using this as portable hdd and then send my pictures via ftp/email to the image developer back in our firm. AFAIK this should be possible. We'll see how it goes....

You are awesome.
yeah, it would be possible to attach any USB device (like on your pc) to the Phone (USB Flash Drive, Keyboard, Mouse, ......... )
cables
I could only find cables in china has anyone seen any for sale in the uk ?
you can make the micro USB to USB 'A' cable with a few bits and a soldering iron or some electrical tape. They seem to be scarce over here so thats what i plan on doing.
i have a "female - female" USB Cable here. if i plug this in my normal micro USB-Cable will this work?
Desire -> Micro-USB-Cable -> Female - Female-USB-Cable -> USB-Keyboard
I ordered from the ebay guy he adivised on his site
@kingchris
Nah this wont work. The reason he uses the powered hub and the special power cable is because the phone itself doesnt give out 5v like a normal USB port so devices are having to steal it from elsewhere.
So with your keyboard setup, the data lines will be connected but it will have no power.
so a normal Micro-USB cable to a USB-HUB and then to the keyboard?

Dont know if you even need the hub. Its the special dual ended power cable you need. Just need some way to pump 5v down towards the keyboard. *i think*
http://www.span.com/product_info.php?products_id=22810
Here a link to a company selling the power cable. Based in Surrey.
i think it will work if you don't plugin as much devices as the guy in the video.
you can use one of these to convert your existing Charging Cable to a Female Port
Amazon.de
or
Amazon.co.uk
Edit: kay, not sure if the gender changer is all you need

Lapdock HDMI

I can confirm that the lapdock does indeed work as a hdmi monitor and usb mouse / keyboard, I had some spare time and tried it out.
*update*
I just spliced a USB A to a micro USB female, works great on my ps3. I just connected USB Rx Tx and ground, Don't bother connecting USB +5vdc red as it sends power up stream and may damage whatever your connecting it to.
here's a video of it in action.

I sent an email to sparkfun inquiring about a micro hdmi female breakout board and here's they're response:

Hi XXXX,
Thank you for your breakout board product suggestion. You bring up a great point about seeing this type of connection more and more. I will forward it on the appropriate people to see if this is something we can make and carry. Thank you again and have a great day!
Take care,
Pamela

Hopefully we see something from this.
great news!

It'd be awesome if you could post some pictures, such as a game console or camera
So far I just connected it to my laptop by holding it. I have an adapter I bought off dealextreme that converts micro female hdmi to full size hdmi. I had to file the female side down a bit but nothing more. If I can find my hdmi genderbender then I'll post it with my xbox360 or ps3. http://www.dealextreme.com/p/hdmi-male-to-micro-hdmi-female-adapter-converter-81206
that is awesome, a female micro hdmi to female hdmi cable is impossible to find I'm sure
What kind of usb slicing is involved?

What are you using the USB for for end-use? USB hub for the ps3?
I'm not familiar with the ps3

The lapdock keyboard and touchpad work just like a normal USB keyboard and mouse. I just used a ps3 as a good proof of concept. But it'll work on anything else that has HDMI / DVI and USB. I'm going to use mine as a cheap rack controller with a KVM.
@callen81, I see there are 2 HDMI to micro HDMI connectors on dealextreme. The one you've posted is $5, and the other one is $4.10. The cheaper one also has a smaller form factor. Maybe it'll fix without any modifications. Anyway, I just wanna ask is there any reason why you've decided to purchase the expensive one? Thanks!
Here is the link to the cheaper one.
http://www.dealextreme.com/p/hdmi-male-to-micro-hdmi-female-adapter-66079
Awesome find callen81!
If I get a "Gold Plated HDMI Female to HDMI Female Adapter/Converter" (search on dealextreme) coupled with the HDMI Male to Micro HDMI Female Adapter, I should be good to go right?
@callen81: Out of curiosity do you happen to have Rock Band 2 with a Rock Band 2 Guitar? If so, I'd love for you to run the auto-calibration test on the Laptop monitor and let us know what the Video Response Time is (aka input lag). If it's under 16.6ms, then it is considered sub 1 frame lag. If you don't have this, I'll do this test myself when I get my Laptop monitor up and running and report back!

I don't have Rock Band, that HDMI micro female to HDMI male looks identical to the one I have. Looks just to be cheaper? As well I just used a hdmi female to female gender bender for a wall plate and it seems to have worked fine. A HDMI extension cable would probably be ideal.
Where did you get the female micro usb as well? FRom video it looks like the hdmi adapter takes up almost all the room so I am just wondering how hard is it to fit them plugged in at same time
Is there anyway to make an extender (female to male) for both the HDMI and USB connections? I would love to be able to use my atrix as a webcam for skype or goggle talk since the screen blocks the view of the phone when the lapdock screen is up.

I had to file both the hdmi and micro usb female plugs down a bit, far as an extension cable for the atrix itself it wouldn't work as more then usb data is sent though the usb plug.
Mac Mini?
All the more reason to pick up the dock while its being sold for $50 on ATT.
Someone should connect this to a Mac Mini and you would have your very own PAAH (Portable as Hell Hackintosh)

You should look at the pandaboards, full opmap4 dev board with hdmi.
I plan on doing the same thing.
Ordered two of the link below thanks to your testing.
hxxp://wwx.sparkfun.com/products/9614
Plan on soldering them together to make a clean adapter. (Without the +5v connected, or with to power a beagleboard using the OTG port)

How to make OTG work?

I bought a micro usb to female usb adapter and I've tried using Faux's kernal, Da_G's .42 kernel and Bullet 2.9 but plugging in the adapter with any usb does not seem to work.. is there any app I need or like how do I verify that it works?

Nope it should work right away. What are you trying to connect? Also, it's possible that it's a bad adapter.

YOU NEED AN ACTUAL OTG CABLE, NOT JUST AN ADAPTER.
Yes all caps, this has been stated time and time again, some people have had luck with the i9100 cables , some have not, you need a cable that works with either the t989 or Hercules, but, I have tested one that was made for the Xoom and it worked as well ...
Well I bought it online and I'm assuming it was made for OTG because what else could you possibly use one for? idk maybe there's another use for it but I can't think of one.
I read something online about shorting the 4 pin to 5 or something, could that work?
And I've tried connecting 3 different flash drives

Yes that could work, that is usually what a OTG cable does, but depends on the phone, the regular adapters are used, to use an Mini USB cable/charger on a Micro port , I use them all the time, because I have dozens of older chargers ....
Ok so I ripped open the adapter and the build quality was too good so I had to just rip the heads off lol so now I have a micro usb end with no wires connected and a female usb with no wires on it. Can I take 5 thin wires and connect the appropriate pins on the micro usb end to the corresponding pins on the female one?
If anyone has a guide to do this, it'd be appreciated

Thanks I tried working it for about half an hour but i couldn't get it to work. I'll just have to order one that is specifically for OTG.
Just as a reference for other noobs like me, the wire MUST be otg for it to work

Looking for Dock with outputs

Hi, thanks for looking.
I am after a desk dock which has a charging port, USB port and HDMI-out at the rear.
I would appreciate any recommendations.

Lol, we all are. But from what I hear you can't have MHL and OTC USB at the same time.
Your best bet is Bluetooth mouse and keyboard.

What would you want to try with that?
Are you referring to something like this:
ebay.com/itm/Hot-Mini-A-5P-5Pin-USB-Male-To-Micro-B-5P-5Pin-USB-Female-Extension-Data-Cable-/290699800110?pt=PDA_Accessories&hash=item43af0eee2e
only then with the full type-a plug on the male end?
I thing he means for Micro USB otg cable. You can get them for a dollar on Ebay.

No I mean a normal (not otg) that has a full sized usb male side to a micro usb female side.
Oh well I guess they don't exist.
you can always buy the two cables from a thrift store and then splice the cables yourself.

So are usb cables just connectors? Like can I just wire each pin to the exact opposite pin? Or is it more complex than than?
