Can't find much information for the Xperia Z for what I am looking for, so might as well ask.
USB OTG, from what I can gather, will only allow us to play media on a USB stick, but not charge at the same time.
What about using a QI Wireless charging kit which connects via the two exposed metal plates on the side by the USB port? If we use this method, can we still use USB OTG functionality at the same time as charging?
If so, brilliant, I can then figure out a method of integrating a QI charging kit into my current phone case for this phone

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.

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.

I was thinking, I have a MHL Cable which charges my phone while connected to my HDTV, but I was thinking, what if I buy a DK31 Charging dock.
Will it charge faster because of DK31 + Micro USB? Or one of the power sources would be ignored?
it should
try and report it
The USB port is not accessible when the phone is in the dock. So you cant connect the MHL cable

This. The same concept was tried with the Nexus 4 wireless charging orb. The USB connection was ignored and it only charged wirelessly (or maybe it was the other way around. Either way, it only used one)
There is no wireless charging on the Xperia Z1

Hey guys,
I was looking at the Samsung smart dock :
( can't insert link as I am a new Member)
And was wondering if it would work on the Xperia z1?
I know that the z1 supports MHL and OTG so I'm guessing it could work..
Also, I realise that the actual phone won't fit onto the dock properly but I really want hdmi out with at least 2 usb inputs, so I'm fine with using a micro usb male to female cable to run from the phone onto the dock.
This is my first post so let me know if I'm doing something wrong
Thanks in advance

It's a hardware issue actually, Samsung uses special usb connectors which can active both mhl and usb at the same time, not sure Sony does too...
Sent from my C5503 using Tapatalk
I use something like this and it works fine to have HDMI out, but never tried using the USB in at the same time.
You can use the usb as storage or only for charging while using hdmi?

I heard that the USB input on that could only be used for power and nothing else.. :/
I think that's correct, as the HDMI output does not work unless there is AC power going to the Micro USB in.

Theres a cheaper version of the dock on ebay for $11 which has HDMI and USB (both full size) ports. I might buy it and try that one first.
A stupid question, how can I use the MHL cable and charge the Z1 in the same time? It is possible?
spam, delete
OK technicaly it's possible to fit and wire up a USB port to the headset and cut a port hole out. But we need some expert help here to be honest there ain't much in the headset so fairly possible any help would be appreciated pics of inside etc.
Yeah have actually thought about this... thinking i may attempt. Woundering if we could use a samsungs mhl dock circuit to use the hdmi out at the same time as gearvr

What we need is when the new gear vr is releases a teardown and see how the micro usb is attached and mod one our selves.
If you can find the pin out for charging, then you can probably wire solder a female micro USB to it.
Why not using a wireless charger with a qi wireless receiver card on the Note 4?
Wireless charger probably won't keep up charging phone while using vr apps. Wireless chargers usually output around 0.5A or a little more while factory wall chargers - 2A
