Looking for a cable that can usb otg/power at same time(Future Car install)

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.

I am interested in this kernel patch quite a bit. I have a galaxy note 2 (sprint version). What are the odds someone has figured out how to get power and otg working on the note 2?

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.

HD/HD+ usb host cable

Due to proprietary port used in Nook HD/HD+, standart usb host cable does not fit.
Did anybody seen anywhere Nook HD/HD+ port <-> Usb Female cable?
I need such cable to attach keyboard/flash/... to my Nook.

I'm looking for the same thing, no luck so far. Anyone find anything?

There is a chance to have mode switching via software and use female to female adapter with stock usb cable

Is mode switching developed on a per hardware basis, or is there a general app that will work on the hd+? I think its per device . Guessing no one else has made any headway with OTG yet?

I'm sorry, I was wrong with previous post (deleted)

Unable to get usb Nook Hd + to recognize any usb input
I downloaded the zip mentioned in the first post. Previously I was on a hybrid version from Android for Nook of 4.1.2
I have tried mounting with chainfire and nexus media importer but not seeing any drives. I have tried two different flash drives a mouse and a ps3 controller with powered usb hub. None of the devices have been detected.
I have gotten usb otg to work for a nexus 7 so I'm not a total noob. But far from expert as I can't get usb otg for my htc evo 4g lte.
Under settings it showing the custom rom that you linked here.
However I may have installed incorrectly as I can no longer get into Nook mode. Only Android mode seems to work now. Any help would be greatly appreciated.

If you installed the version linked in the referenced post above and it said ...emmc.zip in the name, you installed it to internal memory replacing the stock Nook HD+ OS.

Layout
I have a few extra Nook HD/(+) cables and am thinking about doing some wiring. Anyone have a pin layout of the Nook HD plug, so I don't have to tear it apart? Or are they using standard USB wiring once it leaves their proprietary connector?

i am not the most skilled in this area but i am also looking for documentation on the pinning. i am thinking if the whole connector is actually connecting (can use all pins) we can do a lot more than just otg this could allow powering of the tab and data at the same time, possibly with a custom rom and hardware permitting display out with power and data all at once. but thats being super hopeful haha

ah thank you for the heads up, i also read that someone found the hdmi pinning (probably took apart that hdmi adapter) as well but no pinout was shown :/ but hey that means were getting closer!

Hardware hacking?

Has there been any attempt at hardware hacking the Nook HD+ ?
I just bought mine on Monday, roooted stock and Im loving it but I hate the 30pin proprietary connector.
What I would like is a small dongle, the size of the hdmi adapter, that has a female mini or micro usb coming out the side for OTA. Or maybe one on either side for OTA and charge or OTA and microSD.
Are the pinouts of the stock connector available? I could get a stock cable and experament with it.

Actually not much done on hardware side if we leaving out FCC official HD+ teardown flying over the net and my teardown. But i can say that my this testing item still half opened and i can make "animal testing"

[Q] USB2 HDD and/or keyboard on KFHD7?

I know the KFHD7 can't power things plugged into the micro USB but assuming a USB hub or power from another source just having the data cable plug into it should work, right? I've tried a USB2 HDD and USB wireless mouse/keyboard and they don't work though, although they do on my Samsung Galaxy S3 using same apps to mount in case of the USB2 HDD.
If this is possible what am I missing to make it work?

i m going to explain you why you cant use them (i bought a keyboard) amazon disabled usb otg in the kernel. i said amazon to turn it on. i contacted them 2 times, and nothing. i think, we have to contact them to enable it (all forum users) or pay me 35 dollars for a bluetooth keyboard!

Damn, lack of USB OTG support is a real shame, I was hoping to use the KFHD7 as a portable media centre/laptop replacement but it might be impossible by the sound of it.
One thing i forgot to mention is that my KFHD7 is modified with TWRP and CM 10.1, runs really smooth compared to the stock software. But is USB OTG stillnot possible like it was on the original Kindle Fire? Seeing as this newer one uses a second bootloader and all.
