Can I charge the note while in USB Host mode?

So I built a USB OTG adapter by shorting the ID pin to ground on the USB connector. This makes the Note go into host mode and start providing power out so it can talk to memory sticks and mice and keyboards.
Can I somehow through hardware or a custom kernel charge the note while in Host mode?
I want to build a little custom circuit for my Note that lets me charge it while in my car cradle but still talk to various USB devices like my OBDII adapter.
Yeah, nerdier than most Q&A, I'll try the development section if I do not get an answer.

I'm modifying an HP Ipaq keyboard from its ipaq interface to micro USB for my Note. I'm planning also putting in a powerpack and tiny powered USB hub to make the power connection.
If you got a small USB hub and gutted it then would that help?

I'm not sure if it will work but I plan to find out once the ebay sourced parts arrive

Dude, there is a small (but non-zero) chance you could permanently screw up your note doing what you describe (which is why I am asking the question instead of just hooking up a power supply and seeing what happens.
Most likely, nothing bad will happen but it won't work. You'll have two voltage sources fighting each other trying to push current in opposite directions but the relative difference in voltage will make for very small currents.
Worst case is you will fry something in your USB OTG chipset by shoving current into a system designed to push current out.
Second worst case is your battery pack goes boom because the Note is pushing current in to a regulator trying to push it out (unlikely).

So... PurpleMelbourne, what happened?

Bump, I am still very much interested in this. Any help appreciated.

Are you sure its 11pin not 5pin?

When that happens with my Note 1, I power cycle it and its adapter starts working again.

How can you tell if is 11 pin?
My old mhl still works on note one, htc sensation and skyrocket doesn't work on note2

Look at the MHL micro usb connector. You will see a 2 step connector. 6 pins on the lower step, 5 pins on the inside step. You can also look at the Note 2 micro usb plug and you can see the 2 step connector pins.

Lol it was fake

Is your Samsung MHL adapter like this...
Mine cuts in and out (both video and audio), and wiggling the entire set of attachments seems to bring it back. I've replaced the hdmi cable and power adapter / cable to no avail. Also, the power plug into on the MHL adapter seems very loose at the pin connection. But even with the charge indicator on, the video/audio signal cuts in and out randomly.

[Q] Need some help with my Micro USB Slot

Hey,
My N7000 suddenly doesn't want to charge or connect to pc.. I tried with several other cables and they all don't work.
The phone only charges when I push the MicroUSB plug downwards.. I think I twisted my phone in a wrong way when the charger was plugged in or so.. Can i repair it?

If you have the expertise then yes by ordering yourself and new one and changing it. Lot of videos on that.
Have you tried to check if all the pins in the port looks ok. Not twisted and touching each other.

Or warranty. I swnt my year old note off last week and got ot back yesterday (2 year warranty in UK) all fixed nicely

Clean your micro usb thoroughly using a pin or tooth pick. Make sure you get out all the fuzz and then it should work. Get right under the tight spot of the micro usb where most buildup is.

Charger cable with short plug

Does anyone know of a charger USB cable with a really short / stubby micro USB plug piece? I have my Nexus installed in the car, and due to the size of the plug that goes into the Nexus, it gets pushed to an angle by the dashboard, which causes things like my USB flash drive to unmount suddenly, USB-DAC to lose signal etc. I have tried both with the charger plugged directly into the Nexus, and using a 90 degree adapter, both are just slightly too tight and I am afraid with the pressure on them may cause damage to the connector on the Nexus itself.
I am hoping to find a USB cable with a stubbier plug, or possibly even an OTG cable with a 90 degree connector on the end of it. Either one of these should give me an extra couple mm in order to not run into this problem.
Thanks.

Have you tried something like this?

Thanks for the link, I have not tried one of those (yet). I did find this link searching around yesterday and ended up ordering the down angled cable. It's not cheap for a 5" USB cable, but should work and give me a little extra slack for plugging/unplugging the Nexus.

USB hosting?

I realize since its 4.0+ it should, but I haven't heard anything concrete one way or the other.

I think ICS has the support, but the connection will be an issue. Impedance due to the cable size will likely create minimum power threshold issues.
Is there a shorter cable, or other connector option? This ties into my review concern of the proprietary connector.

Yea, I was thinking about that connector as well. I could use bluetooth I suppose, but I've found that things just seem to work better for me when I can plug it in.
I do have a micro to standard usb cable. Now that I think about it, I should try that with my fire hd.
My wife is giving me crap about wanting the hd+ after I saw the mothers day sale on it, she says the old nook color is still working fine...
