[Q] Host USB on Droid 4

Does Droid 4 have Host USB capability? In Lapdock it should but what about other methods.
Theoretically Droid 3 didn't have HostUSB functionality, but when you did connect it to Lapdock or HD Dock with USB the ports were supported and there were even app for supporting flash drives. The only with ancestor was that USB didn't have power so you couldn't use cables that have microUSB/USB to connect devices.

droid 4 will do usb host with a few caveats.
It will only do fat32 formated flash drives.
you need to power the drive off another device.
basically you need a usb otg (micro male on one end, usb female on the other) and a usb hub that uses an ac adaptor. The hub with power cord provides the power for the device, and the OTG cable is for the data. This can also be achieved using a powered y cable in place of the hub, but you would need to have the power-only usb port plugged in to a power source.

Has anybody tried Remote Release with the Droid 4? It does Canon DSLR and normally works with Galaxy S2 and 3 without rooting.
Using a USB OTG cable I've connected my Canon DSLR but I had now joy unfortunately...it doesn't recognise anything. Also I've tried keyboard and mouse but that doesn't seem to be working either. Am I missing something

Thanks, I've seen this already. I guess what I was looking for is to understand whether everything OTG needs power or just things like keyboard/mouse/pendrive - things that actually consume it. TBH the DSLR camera itself is not actually being charged or anything, it is just DATA, so I was sort of hoping that I can avoid.

Out of all the devices i have tried all have needed external power... prior to the purchase of an HD docking station I just used a powered USB hub with an otg cable....

I think I've made an assumption that it would behave similar to my android tablet, just plug in the pendrive and it's all good. I have defo came across devices that don't need external power, especially for a camera that doesn't take power.

Do you think this would work?

I found this item on Ebay - OTG Micro USB Host All In One Card Reader For Samsung S2 i9100 i9300 i9220 i9250
(search for item # 390452881730)
it seems like it should work assuming you have stickmount installed. Anyhow have an adapter like this?
I was going to get the regular cable - but thought this would have the sd card reader built into the cable and could be handy to only have to carry one cable (vs multiple cables/adapters)

It claims to be for the Galaxy S2/3 so it should work fine. It still needs a cable so I can't see where the advantage lies over an otg cable and usb stick card reader, that said it's cheap so go for it.

So hold on, this adapter would still need the otg cable? The description says it is an otg built in... not sure I follow you.

It doesn't need an otg cable it plugs right in to your phone/tablet. This is what I have been looking for for so long man thanks for finding it! I do photography and this is gonna be so awesome to sort photos from a shoot without having cables everywhere and movies on long flights. Double thanks for you!

i gotta get one of these to stuff in my camera bag for work, thanks for the idea !

When I said it needs a cable I meant it connects to the tablet by a cable, not an otg. I'm going by the images in the eBay auction which seem to show a micro usb socket on the back. If that's the case I can't really see the advantage, as I said ^

Looking at the images, one would think that if your N7 is in just about any case you wouldn't be able to connect this easily. I'll stick with a cable...

Micro USB to HDMI Adapter

The razr i has only got a micro usb port you probably know...
Somewhere i heard it would be possible via an adapter to get hdmi signal out of this port...
Can soneone guide me to one of those adapters or is one already shipped with the device?
Thanks

One is not shipped with the device, but if the USB does support HDMI out that would be fun to try for inclusion in other mods.

You'll need to know if the razr i is MHL compliant. If not you should not be able to have HMDI output on the microUSB.
If so, you'll just need a MHL adaptator, something like this:

EDIT: Cancelled.

Apparently it doesn't work on the M, so I'd be surprised if it worked on the i. It will be cool if it does, though.

it does haves a dock app do ,and somewhere in manual and info papers that comes with the phone, you can read several statements that point to a dock port

Hi Robert,
Do you own a PS3, XBox or Apple Tv????
The reason I ask is because if you download app called 'DoubleTwist' from google play store this consolidates all of your music and videos into one application instead of having seperate apps for each.... Once you have this downloaded and all your content on you can download there paid app called 'AirTwist' for double Twist.
once you have these 2 seetings you can wirelessly send your videos and music over any wifi network to a Playstation 3, Apple Tv or Xbox and no need to have cables lying round and probably costs the same if not less than buying the cable!
Hope this helps and if so please don't forget to press the Thanks Button on the left under my user name

HDMI Connection Kit

Does anyone have one of these that can tell me more about it?
http://www.ebay.com/itm/New-Micro-U..._PDA_Cables_Adapters&var=&hash=item3cd4db7fb9
Looks like from the bottom of the listing it states:
"Attention: The MHL, OTG,Card reader and Charge function only can be used one at the same time. cannot use it together
all functions can be used only when the adapter is being charged"
Not a bad price, but if I can't at least use HDMI + another function like SD card or USB peripherals it seems a little redundant
Thoughts?

Hi.
Have you received your HDMI kit yet? Does it work?
I received mine today but unfortunately, the HDMI function does not work at all, I don't know if it is my TV or the device is defective.
The OTG function works only if external power is plugged in which makes this device almost useless. There is no way to plug in the external power and SD card at the same time.
My phone is running Jedi X16.
Update:
I read the instruction manual and confirmed that external power supply is required for all functions of this device. So we can forget about using it as a portable OTG doggle.
I also connected a USB keyboard and a USB mouse to it and both worked at the same time.
So the remaining question is whether the HDMI works with Jedi X. I tried it on two Panasonic TVs and both didn't work.
2nd Update
Read the forum and found that I have to turn on Airplane Mode for HDMI to work. My phone did detected the HDMI cable but no video out. Used my other cheap MHL cable and video was displayed on my TV. So it seems that my device is defective.

Any updates?

It works as an OTG adapter but you have to plug in power first to make it works so it is not too convenient.
It didn't work as an HDMI adapter no matter how I connected it to my TV.
Initially I thought it was defective, the seller had sent me an replacement but with same result.

I have the official mhl adapter from Samsung. Bought it on Amazon uk at a great price. Must buy from Amazon and not from of the other sellers from Hong Kong
Anyhow just mentioning that it too needs to have power supplied for it to work. I just plug a cheap usb cable into a usb port on either the satellite decoder box or the tv and that works fine.
Btw the Samsung mhl adopter works amazingly well. I've had absolutely no problems using it to watch Netflix, streaming tv, YouTube, or playing videos from the sd card. Everything I've thrown at it works really well.

One of these hdmi/usb/card reader devices?
I already have a cheapo MHL adapter which works fine (yes, you need power plugged in). But I wanted to add USB OTG, and this seems the only device that will give it to me on the cheap. So I'd really like to know if anyone has one that works with HDMI and USB at the same time.
I also find it hard to believe how so many sellers out there can be selling these when it's physically impossible to plug in an SD card at the same time as the micro USB plugged in for power. That's obviously a massive design fault.

Once the connection kit and the power are plugged in and the phone detected the existence of the adapter, you can remove the power and insert the USB drive or SD card.
