Long time lurker. First time poster.

I have a 10.1 Note Model # SM-P600 that I have set up in my car. Currently, the charging works fine via micro USB to engine/ignition accessory. Now that I have the initial steps completed, I am looking to add more stuff to the setup. I purchased a USB hub in order to connect a few different devices (USB DAC, External HDD, Camera, etc) along with a few different OTG cables. So far, I have not had any luck charging the device (although, I am able to access devices connected to the hub via the OTG cable). I understand that this is a common problem, and it seems that it has been solved on some devices (Nexus 7) by installing different kernel's and USB ROMs (not sure what this is?). However, I have only seen one bit of information in regards to the SM-P600, and that is the BinDroid kernel that I have found here:

I flashed the kernel correctly (I believe, I see the kernel information showing up in my device information), but I am still not having any luck getting the device to charge while having the other pieces of equipment attached. Can anyone give me some good solid info on this problem? I thought I'd be able to install the kernel and that would fix my issue, but maybe I'm missing a few steps? Do I need to install something else? I am currently on the stock ROM, version 4.3. I was thinking about putting CM10.x on the tablet, but I don't think that it's supported...? I need a bit of clarity on that as well.

Please help if you can. Thanks!

P600 needs 2A current. I think when you attach other equipment to the USB hub, it may not be able to provide enough current to note so it will not charge. I am not an electrical engineer so someone with more knowledge can of course prove me wrong

Generally when your device is connected with an OTG cable, your device is working in as a USB host supplying power to the devices. In your case, your Note will try to supply power to the USB hub. Even if your USB hub is powered by a separate adapter, your Note will not attempt to charge as it is in USB host mode.
