Where is this at for the tab. Has anyone found it yet. I dont know if maybe froyo does not support the usb host mode needed or what. I saw that it was comming and yet cannot seem to find it. It was supposed to plug into the data port on the tab and give you the ability to attatch regular usb peripherals.
Any info is greatly appreciated

FWIW I saw a USB dock at Home Plus (Tesco for you guys in the UK) the other day for 29,000 KRW. Although I can't be sure, it appeared to be just a USB only dock but it looked like the HDMI dock recently reviewed on here.

you should try out the Elan Mobidapter, it's a micro SD to USB adapter with integrated USB Host. i'm using the Mobidapter often and im happy with it, but you can only use USB Storages with it. No keyboard support.
BTW: Android itself doesn't have or support an USB Host.

That's not entirely true. Most android builds don't have the necessary usb host support as part of the kernel, but there's nothing to prevent someone from compiling it or adding it in as a module. The Tab is/was supposed to do this OOTB, and based on the pinout information posted elsewhere, there is at least kernel support for determining if host mode should be enabled. With a modified iPod connector from Sparkfun I was able to get the Tab's AccessoryManager process (I think that's what it was called) to see a non-supported device plugged in (externally-powered USB hard drive enclosure), even if it couldn't enumerate it. It could be because I didn't connect the requisite +5V for downstream devices, or because there is no usb_storage module available. More testing needs to be done on this before we write it off completely. Hopefully Samsung will just release their solution(s) sooner than later.
That is what I wish they would do. But im afraid with the tab10.1 it may be put on the back burner

How did you modify the ipod connector? I have a few ipod/iphone cables lying around but they seem backwards compared to the sgt connector and difficult to modify.
I'm thinking about buying some sgt connectors or cables from china to play with.

Unfortunately I could not find a supplier of the "mirrored" iPod connectors that the SGT uses. I contacted many China-based component mfgs and none could point me in the right direction for that stupid dock connector. So I got the iPod one from SparkFun, used an xacto knife and small file to grind off the material on either side of the connector that keys it into the mating iPod connector. This allows you to invert it and plug it into the SGT, which then gives you access to all 30 pins. The cheap charging/sync cables that you can get from ebay and the likes only come with 5-7 pins connected, and the rest missing.

you know what sucks? I had a $100 haipad that had a microusb jack and came with a 6" adapter cable. guess what? you could plug in usb sticks, a usb mouse, or a usb keyboard. worked perfectly. mouse had a pointer, keyboard worked without a popup, it was all quite magical.
that was on a 2.1 resistive touchscreen chinese tablet.
why the hell can't the tab to this?
I have everything planed out for my tab install for my Dodge Magnum. But since the Nexus 7 doesnt have a sd slot I need to find a cable that can charge the tablet and use my flash drive at same time.
My flash drive(Usb on dash, so its easily removable)

Plugging this into the usb otg cable
http://www.amazon.com/Black-4-Port-...qid=1348442221&sr=8-3&keywords=4+port+usb+hub
I would love host cable with 2 usb inputs but cant seem to find it and dont know if its even possible.
Any help would be appreciated.
I found this on the bay : item # 140839631580 (Can't post link I'm too new... I was a lurker for a while -_-)
i didn't think the N7 could support power and OTG
You want it for video or audio? You could try a wifi solution for audio. Or be the guy that gets the pins to work.
there is NO data and charge at the same time. This is due to how the device switches from charge to usb mode thru the pin 4 . it senses rather a data cable or charge cable is being used . will not charge via otg..
there are several threads with experiments trying to get this work .You could use a wifi or bluethooth drive for data...
I have no clue what im doing but this is what im playing with at the moment. Its a old dock for sgs2 i believe but it has a dc and usb input on the back of it.
Im about to this because i have very little patience for china.

Would get the cheaper one but the juiced one has a flexible cable vs the fixed usb on the other one. Would this be pointless though?
Unfortunately OTG sends ground up the sense pin to trigger host mode. Once activated it sends 5V DOWN the USB cable to power your USB devices. Trying to send voltage up the cable at the same time to the Nexus would not be a good idea. The only way around it I can think of would be to hack the firmware to only activate the data pins in host mode and keep the power circuit seperate, then you could power the USB device from a modified dock/hub which sends power up the USB cable to the device.
A lot of work, and without the powered hub, OTG would be useless!
In the long run wouldn't it be easier to just plug in the power lead when needed and have the otg in the rest of the time? (or vice versa). It would mean you having to have easy access to the usb port but I can't see an easy non technical solution to connecting both at once.
Don't use the Nexus 7 for a car install. You can get an Acer Iconia A100 with a full-size USB port to connect to whatever external storage solution you want, and it's usually about the same price or cheaper than the Nexus 7.

Would it be possible to charge while using an OTG Cable for Keyboard/Mouse or does the same principle apply as inn data via OTG & charge?

Same principle. In normal OTG host mode the tablet powers the peripherals. A USB keyboard/mouse will be no exception to that.

Sorry to resurrect an old thread but was wondering if you ever ended up getting that Juiced systems adapter and if it worked well with the N7. Been looking at it but haven't found any success stories on XDA with the N7, just the few Amazon reviews...
That cable would work but u need specific kernel tweaks for otg + charge to work. Pm me if anyone needs it.

Ofcourse there is charge and otg at the same time by just simply shorting pins 4 and 5 with a resistor,in my case for xperia p , a 100k resistor does it.
Timurs USB ROM from another site is what you want. Has links and everything you need.
I was going to do a car install as well but after sourceing parts and work estimates ( I want clean install, like stock) just more hassle than its worth for me. Please post pics if you get an install going.

Hi team!
I was looking to get some input from the forum members about creating an adapter for the nexus 7 that would be a male micro USB input that had 2 USB inputs and 1 female micro usb. The function would be to be able to use simultaneously, a mouse and keyboard while charging your tablet. Also obviously you can pair a mouse and keyboard to one BT node, so it could leave a USB input available for thumb drives, externals ect... Would you guys buy one? Whats on the list of accessories the nexus 7 needs and new models to come?
Thanks for the input.

Wouldn't a pogo pin adapter let you do the same thing? I know there would be a big market for that.

Whats a pogo pin adapter? And those are available already?
The pogo pins are the dots on the left side of the device. They can be used in a dock, which does not exist yet. I don't know if it's possible to make an adapter for the pogo pins that works without the help of gravity.
For your USB-only adapter users would need to root and flash a kernel that's capable of OTG charging (like the faux123 kernel). Normally the host device (Nexus 7) feeds the OTG-peripherals with power. It can't be charged over the same micro USB connector. After switching the kernel to OTG-charging and replugging the peripherals, the host device can be charged by your adapter.
Does anyone know of a charger USB cable with a really short / stubby micro USB plug piece? I have my Nexus installed in the car, and due to the size of the plug that goes into the Nexus, it gets pushed to an angle by the dashboard, which causes things like my USB flash drive to unmount suddenly, USB-DAC to lose signal etc. I have tried both with the charger plugged directly into the Nexus, and using a 90 degree adapter, both are just slightly too tight and I am afraid with the pressure on them may cause damage to the connector on the Nexus itself.
I am hoping to find a USB cable with a stubbier plug, or possibly even an OTG cable with a 90 degree connector on the end of it. Either one of these should give me an extra couple mm in order to not run into this problem.
Thanks.

Thanks for the link, I have not tried one of those (yet). I did find this link searching around yesterday and ended up ordering the down angled cable. It's not cheap for a 5" USB cable, but should work and give me a little extra slack for plugging/unplugging the Nexus.
sorry if this question has been asked already but i looked around and cant find a answer. other than building your own, where can i buy/order one in the US? I want to root my new chromecast but cant find one. a link would be greatly appreciated

A powered USB hub should work Just test it out, the worst thing that could happen is that it will boot stock image, just pull the power to stop it.
Hey guys.
I'm in NYC for a few days and I'm looking for an OTG cable, powered or not. At best buy and at radioshack they look at me like I'm asking for the impossible. I'll be in towns until Tuesday, and I'd like to ask if anyone knows a store where I could buy this cable.
Thanks in advance.

Sorry to say, I have yet to see a powered OTG cable in a retail store, even my geeky local "has a majority of stuff Monoprice carries" store does not have this particular type of cable.
If B&H Photo/Video has these in stock, it should work (but it'll cost more than getting the OTG cable on eBay)
Pioneer DJC-WeCAi 2.6' DJ Controller Cable - $29.00
Neutrik NAUSB-B USB Female Type-A to Type-B Converter - $5.21 (If you can find an equivalent that's not designed for panel mount, all the better)
Comprehensive On-The-Go USB A Female to Micro USB B Male Adapter Cable (4") - $2.99
-OR- NTW USB Type A Female To Micro USB Type B 5-pin On-the-Go (OTG) Pigtail Adapter - 4" - $5.99
-OR- StarTech Micro USB Male to USB OTG Host Adapter Female (5") - $5.99
$37.20 or $40.20 (if you go with a more-expensive OTG adapter) plus tax...
more expensive than the Chromecast itself but everyone has priorities.
Connections would be:
Pioneer cable RED A (flat) end --> Chromecast wall power adapter
Pioneer cable BLACK A (flat) end --> USB OTG adapter cable
Pioneer cable B (square) end --> USB A-B converter --> plug your USB Stick in here
USB OTG adapter cable --> Chromecast
You might find the right parts to get this cheaper, you just need to plan it out in your head. I was just sticking with stuff B&H has since they're in NYC.
Thanks,
I was planning a visit to B&H, but now it became mandatory.
I'll try the one from #3. I could wait until I get home, but can't leave NYC without rooting or bricking my Chromecast, in my hotel room.

Just so we're 100% clear, you'll need 3 total pieces to make it work - the Pioneer cable, the USB A female to B female adapter, and one of the OTG cables.
I also hope you've already checked your serial number against the rootable serial numbers and you know that the hotel's TV may not have HDMI enabled, and even if it does, its WiFi probably won't allow Chromecast to work.
If you brought your own wireless router, then you only have to deal with the TV though. Actually, if possible, I would take everything you need
with you to B&H. If you explain what you're trying to do, they might let you borrow an input on one of their TVs - then you won't have to worry about the hotel TV being locked, unless you already know it's not.
Good luck!
Just to add these cables are usefull for more than just hacking a Chromecast.
I use one to connect Hard Drives to my Xoom (Tablet) since my ROM supports OTG.
Sn are 3920 3921 3922, this shouldn't be a problem. Ref cables I'll take a look at the links later at the hotel. Thanks for your input.
