I just got the Samsung Multimedia Dock EDD-S20EWEGSTD
I don't know if it is supposed to work this way but if it is, then it's garbage. The problem I'm having is that the USB ports only work when the phone is fully charged. I tried the OEM charger cable/adapter as well with the same result. I thought the USB ports were defective but later tried it after the phone had fully charged and everything worked as it was supposed to. I thought it was because I had used a different HDMI cable and plugged it into a different monitor but the next time I tried it the USB ports weren't working again. The only thing that changed is that the phone isn't fully charged now.
DO the USB ports work if the HDMI isn't connected? I tried to see if it would work as a multi charger but there was no output from the USB ports at all when the HDMI wasn't plugged in.

I have the official Samsung desktop dock for the GN with pogo pins for charging. I cut out a notch in the left side of the dock so that I could access the USB port on the phone when it's docked. I'd hoped I could then attach a USB OTG cable and mount a flash drive while the phone charged via the pogo pins.
Unfortunately, the two functions seem to be mutually exclusive. If the phone is in the dock and charging and I attach the cable and flash drive, they are not recognized by the phone. Or, if I attach the cable and flash drive first and mount the flash drive before placing the phone in the dock, charging doesn't initiate when I put the phone in the dock.
Does anyone know if there is some way via software or hardware to force pogo pin charging while a flash drive is attached and mounted via a USB OTG cable?
I will try tomorrow on my self built car pogo charger and usb otg. I have aokp with the fast charge override feature.

Sounds great! Thanks much. If it works, it'll tempt me to go to AOKP myself.
Any luck on this?
I too want to use OTG functionality while charging phone in the official car dock.
USB OTG + charging
I'm actually trying to get the same get something like this going on a galaxy s2 (the I9100g with the omap processor) or a GN, My goal is to get usb host and charging going through the same cable. By making some changes in the kernel i've got the phone to think its in charging mode while in host mode, but if you check the battery status, it's still draining even though it says "charging" and I've got the a usb "Y" cable connected to a 5v 2amp power source.
I think cyanogenmod (there was a post on this here and a standalone app that eventually rolled into the latest cm7 nightly) has this working on a BN nook color (also TI-OMAP Processor), but I have not been able to verify this.
Does anybody have host+charing working on any device with an OMAP processor?
Sorry for the delay, I had an emergency work trip offshore on an oil rig. I can try it out tonight.
Results. Charging OTG killed pogo charging. I tried mounting in pogo charger with OTG already attached mounted with a basic thumb drive. Charging never started. I tried charging with pogo first, then plugging in OTG, charging stopped. I checked to make sure it was actually discharging by waiting for a few percent decrease.
Sorry, I was hoping it would work too.

Thanks for giving it a try. It would be interesting to know if this behavior is built into the hardware or could be modified via software/in the kernel. It's consistent with what happens when using a powered USB hub.
Other than a software mod, I'd sure like to see someone start making and selling an Accessory Charger Adapter as described in Chapter 6 of the USB Battery Charging Specification document from 2010. It's the exact thing needed to use USB OTG and charge at the same time.
Anyone knows if its possible to charge via USB, with a device connected?
I connect an adapter microUSB to USB OTG, than connect USB OTG in a USB HUB and than i connect a device in one USB and force in another, is it possible or not??
It may work, since connecting to the pc works.
I’m having a problem charging my AT&T Galaxy S3 rooted. No USB cables work to charge my phone. Whether it be the one it came with in the box or one from wall mart. I’ve also tried all the USB cables, HTC, Samsung, and others. Also tried the USB mini Best Buy sells for these phones.
Before I had this problem USB cables would work just fine but all the sudden they stopped working.
The only way I can get any USB cables to work is if I hold it at an angle and itll charge and stop randomly but charges very slow if held at an angle.
Only way I can get my phone to charge is if I use a wall charger. I have tried all the USB cables with my car, lap tops, and usb to wall adapters.
HELP PLEASE!

That's a hardware problem.. not much we can do about it. You most likely damaged your USB port and will need to replace it.
You can contact mobiletechvideos.com for their services if you don't know how to replace it yourself.
so i have two usb cables and original. 2.0 amp samsung wall charger, the samsung cable i use for wall charger at home so when i setup my s3 as a AP i need constant 2.0 amp from charger keep up with the demand and charge the battery at same time but now i cant do that i have turn off hotpot and leave the phone alone so i can charge. i brought in my car usb cable, and now i can hotpot and charge at the same time no problem, so what is the problem with other cable? i mean cable still works and i still can use it for data transfer etc...
just cant use as heavy demand cable.
I have some cables from the "box o' cables" we seem to collect that have the same issue. Some of them won't keep up with the s3 others won't keep up with my n7. I notice it more with older cables so it seems to me that its the cable breaking down or wear on the contacts inside the connector itself.
Hi all,
Have a Samsung Galaxy Note 8 running stock Android 4.4.2 I have used an OEM Samsung charger and cable always. But recently had to replace the charging port with an OEM charging port because it completely stopped recognizing the cable.
The install went well and the port works fine.
But I recently plugged in an OEM Samsung MHL HDMI adapter to watch movies on the tablet on my TV. Adapter works great!
The problem arises when I disconnect the HDMI adapter an then plug in the regular charging cable. The cable is not recognized. And it does not charge the tablet.
The tablet will ONLY charge if I use the HDMI adapter plugged in to the OEM Samsung wall charger. I have several OEM Samsung wall chargers and OEM charging cables, but the tablet will now ONLY charge with one specific cable attached to one specific charger and connected through the OEM Samsung HDMI adapter.
I used the adapter once on my Note 3 phone, and it has no troubles connecting to any other charger. But I amit, I am hesitant to attempt to try it again with the phone. I have lost the portability of my tablet now, since it will not accept my portable battery charger either.
Any ideas? Is there some sort of setting I have to change before disconnecting the HDMI adapter? I thought it was hot swappable, although I do not try removing it while it is sending. I turn off the tablet then remove it. Am I looking at doing another charging port install? Is this common with the Note 8?
Thanks for any help.

I had that happen as well not too long ago. Took the blasted thing apart and found that the MHL adapter's usb plugin to be cheap. Had broken internally. So I bought a cheap o replacement. Fortunately the replacment had a good quality usb port, so that said, should not have the same issue.
Think I have discovered part of my issue. The MHL HDMI adapter connector is considerably longer than the standard micro USB connector. This new Port is quite snug. Didn't think much of it after initial installation, just figured that old port was worn out. I think the snug fit may have allowed some shift of the port internally, even though it is screwed in. This small shift is just enough to prevent the micro USB from making proper contact.
I was able to utilize my portable battery pack when in the field with the tablet. Just connected the pack via the hdmi dongle. It worked.
Thank you for your insight.
Unfortunately, I just wasted over $30 on a Valarm IoT OTG Y cable. It does not work at all as a host cable for any USB device on the G4. I was hoping to use the Valarm cable to connect a USB DAC and charge the phone at the same time. The cable will let me charge the phone but whatever I connected to the USB female port is not recognized. If anyone finds a USB host cable that allows charging, please post!

From what i understand otg goes one way or the other it cant act as a host and carge at the same time. It flips the charging circut to flow out instead of in. Ive been through this on a few phones tried even straight wiring a powerline to the otg itll power the usb device but not charge the phone.

The manufacturer of that cable clearly states that it'll charge a samsung phone, not confirmed working on a G4 though. Here is the link, http://shop.valarm.net/products/micro-usb-host-otg-y-cable-with-micro-usb-power-for-samsung
I wish there was a way to enable charging using OTG.

Yea me to i have a few devices that hook to my car that drain my tablet and phone batts and it kills me the only other way ive got it to work is hard wire a charger to the phone. But of coarse this is a old throw away gs3 that im talkin bout not my g4. I havnt tried on my g4 yet but its all phone specs has to have dual charging circuts cause they can only flow one at a time. Now some new devices i know. Do support otg with charging capabilities.
