Hi, before I start, yes I've seen y cables and moded usb hubs but,
I need to know before I vandalize my charging dock... If I have a charger connected to the pins on the outside of the phone, would it interfere with the usb otg? Has anyone tried this before?
Long story, I need to mount my phone and use it as a dashcam, I have 2 apps for this(one for road use, recording to sd card, don't need otg, short trips that gets deleted after a day or so) the other(for off road use, usually recording for hours at a time, so this will go to usb storage, but recording several hours does get power hungry) and therefore I need a charging dock with access to usb otg and the camera. Can it be done?
Another problem with this phone is the hdmi that also uses the same port, but I'll keep that till later.
Thanks in advance for any advice.
P.s. Accessories are hard to find for this phone where I live(the shops only keep for Samsung) so I'll build mostly myself.

i recently bought a cheap USB On-The-Go cable for the Razr hoping to be able to use my droid 4 with the DSLR controller app https://play.google.com/store/apps/details?id=eu.chainfire.dslrcontroller&hl=en but i am having no luck. i'm on stock w/ root, recently did the 219 update with no change. problem is i have no solid means of troubleshooting. i have a touchpad with cm9, droid 1, droid 2, and my droid 4, but i cannot get the cable to work with any of them even for mounting a usb drive. but i'm also having trouble finding solid info on if it should work with any of them.
has anyone had any luck using usb otg with the D4?
Sent from my DROID4 using XDA
I've gotten it working with a cheap Staples USB hub, a USB Y cable (2 male USB one end, 1 male microUSB on the other end for the hub), and a USB charging brick, the USB OTG cable itself. From what I've put together, it's sensitive to where it gets power from. That's why I had trouble with it at first.
Long story short, USB OTG does work on the D4 stock rom, updated and bone stock

Thanks. i actually was fooling around with my touchpad last night and found out it needs external power as well. so with a y-cable from a seagate portable harddrive, i was able to test that the OTG cable i have is indeed working. however, i could not get my D4 to work using extra power from my PC, but I picked up a kodak power brick today and its charging, so here's hoping that works.
actually nevermind, after playing around with a hub and a usb stick, it decided to work with my PC supplying extra power. after that, DSLR controller worked as long as there was extra power supplied. i imagine the battery pack i picked up should work quite nicely. now to go take HDR photos of the entire world! bwhahaha
Glad you got it working. From my reading, the thing to do is get power on the +5v rail of the micro-usb 'input' port, that will allow power to flow from the USB hubs power brick, thru the hub, up to the phone. Can't help you with that however, it's a bit beyond me.
like most MHL cables that include the charging port (where you just plug in from wall), is there anything like this for OTG??
tried finding and searching but nothing.....
If you're looking for power going to the USB device, then you can use this.
If you want to charge your Note while using the OTG feature, then I've not yet come across anything like that.
Just wondering if it is possible to charge the Note 2 while using the OTG yet? I'm in my car all the time and use an external SD card. My 64gig internal card is already full.

How about a scenario where I have External Battery charger and OTG adapter with usb stick. I want to watch the movie on usb stick while also have External battery connected charging the phone. I guess it's the same problem as not being able to charge up phone from any external source while using another device connected to OTG?

You could make your own micro USB OTG cable. I still haven't seen one for sale anywhere.

Oh, I don't have issues with OTG cables. I have adapter and cables, and modified cables before: http://forum.xda-developers.com/showthread.php?t=2107985
I just want to figure out how I can watch movie from usb-stick while charging my phone at the same time. There seems to be no solution for that yet? Or are you suggesting there is a way to make a custom cable to do that? I think once you attach OTG cable to connect a peripheral device, you turn Note 2 into host and it will not accept charging from micro-usb port. No way around it

Oh, I understand what you mean now. In that case, you are correct. You cannot charge your phone and use an external thumb drive at the same time through the usb port. When you plug in an external drive, your phone switches the USB power cables to send the juice instead of receive it.
The only ways I know around that are to use a wireless charge stand or the desk dock.

Isn't this exactly what sammys smartdock does? Charge and otg simultaneously?

Yep. Not possible with just a cable. It needs a microprocessor to regulate the current in and out. Devices plugged into the dock are powered by the dock's power, not the phone's.

I hear what your saying, but looking at threads in the S3 section like this one: http://forum.xda-developers.com/showthread.php?t=1953061 got me thinking... I'm just trying to make an audio cable for my car that charges and has 3.5mm out to my radio. And I need it to work with every 4.1.X kernel and above, especially stock.

If you get a pinout for the s3, might be able to modify a cable to do both.
Since it almost impossible to find a PDMI Port, I retrofited a MicroUSB port.
I even contracted FOXXCON, got a reply contract DELL for replacement part.
I have Charging and Data + / - (Detected by PC) working fine.
Only Issue is that the device shows it's not charging when Power ON and connected to PC (Hardware Charging LED is lit).
-Maybe this is Normal??
It does show charging when power on and connected to Charging Adapter.
I will post pictures when I get home today.

Basically Gutted bad PDMI Socket and Shove MicroUSB port in PDMI frame.
Looked up Pin out for PDMI and Micro usb for data +-.

Are you able to reach Fastboot with this mod?
PDMI connector to mini usb connector
Hello man. My name is Mario. I come from Italy. I'm a psychologist,but on the spare time I like to play with linux & mobile & tablet & technology in general. I was searching for a OTG adapter that was able to recharge my nexus 10 and at the same time that accepts an external sd card and someone has suggests this to me :
eKit 4 in 1 Data Sync Connection Kit For Samsung Galaxy Tab 2 10.1 & Note 10.1
you can read the full story here :
http://android.stackexchange.com/qu...ard-and-recharge-the-battery-at-the-same-time
the problem is that I haven't read very well what he says and I haven't understood that it is not good for the nexus 10. For this reason I have tried to search a way to convert the PDMI connector to a mini usb connector and I have found this thread. I would like to ask you if I can make the same thing that you have done and if you can tell me which electric modification I have to make to the board of this connector to convert it as a mini usb connector. Thanks.
Hi all,
I'm having two problems that I believe are related.
1) I bought the official MHL 3.0 sony cable and my tv intermitently sees the hdmi source. Off and on every second and my phone screen never displays onto the screen. Also the phone alternates saying its being charged and not being charged.
2) With some power sources, charging by micro USB alternates being charge and not being charged off and on just like the above case. But some micro USB cables/sources work just fine. As well my magnetic dock connector charges my phone fine as well. USB hosting is fine too.
Anyone has tried MHL or have had similar problems? Should I contact clove? I'm in Canada and sending it back there seems quite the pain. And if i just can't use MHL or certain cables maybe i should bite my tongue and keep the phone as is. I love it otherwise and haven't phone any faults until trying the MHL cable...
old mhl adapter works
My old mhl adapter, which requires its own power source through micro USB does work and I can mirror my screen to the TV. I just think that mhl 3.0 with power from the HDMI is not enough to drive/consistently power my phone. Same for the micro USB connectors that don't seem to keep a consistent charge on my phone. Anyone see anything similar?
Use Chromecast, the phone has a dedicated cast screen option
Yes I have used chromecast and it works great. I just wonder if anyone has tried mhl 3.0 Sony cable or has had the same chagrging experience as me.
Were you able to solve this? Im thinking about getting an MHL 3.0 cable but not sure whether my monitor will be able to handle it
Evening all
I'm planning on building my own dock for my OP3 to sit on my nightstand and charge at night. The goal of the dock is to charge the phone, but also have two or three USB ports for backing up photos and such during the nighttime hours, as well as an Ethernet adapter so that my phone has a wired network connection as well.
So I guess my question is, are there any powered USB Type-C hubs out there that fit this criteria? Again, it needs to:
--Charge my OP3 via USB C
--Ethernet adaptor
--Two or three USB ports for expanded storage.
I've considered using a Raspberry Pi for this, but I wanted to see if there was anything else first before I dove in to the project.
Cheers
Wow.. Your project is awesome. Please do post the results.
P.S. I have seen a hub like this for another phone not OnePlus 3 although it did not have any ethernet adaptor.
P.P.S. If possible, can you put a diy guide once you are finished? That would be amazing...
idk if this will work as I think our phones cannot charge and transfer data at the same time.. which means you either chose to back up your photos or charge your phone.
but you can try if this will work. its meant for MacBook but it should work ive used a MacBook usb hub on my one plus3. also don't expect dash charging..
