OTG support hardware or software? - Android Q&A, Help & Troubleshooting

Is OTG support releated to hardware or software, kn other words can OTG be enabled with only adding that feature to kernel or I need some hardware requirements beside usb flash and otg cable?

OTG support requires both hardware and software support. If your android is rooted then you can enable OTG support using USB OTG helper
You require OTG cable when enabling OTG support.

You can enable OTG support on any chipset. You required rooted android.

No you cant.
First lets understand how otg works.
First of all , for Pendrive or Storage to work , you need power for it to function.
There are two eays to power up the pendrive.
i)Power from your phone's battery
ii)External Power
No matter how much you tweak your software , without providing power to the pendrive , you cannot run an otg.
You can always google and find out if your chipset supports otg or not.
If your chipset supports otg and your device doesnt , you can always root your device and try StickMount or USB Otg Helper , but if your chipset doesnt support otg , you need to power up pendrive externally , using a usb Y cable.
After you've acquired the cable you may try the above mentioned root applications to try out your luck.
I am 90% sure that your device wont support otg even after providing external power because of your kernel.
Your kernel is the one which controls all mounting point and hardware devices in your phone.
Good luck/

So, if I understood it, if my device doesn't support OTG by hardware, I still can make it work using Y cable, and if it still doesn't work than I need to add kernel support?

Its worth giving a try , usb y cable is available for less than $5 now a days.
For mounting ntfs , USB Otg Helper is mandatory though , even after kernel modifications.
Or maybe libraries can be manually installed
Anyway , Cheers

I needed a tab for my car dash entertainment/navigation so i ended up buying a cheap verizon ellipsis 8 (model QTAQZ3). Its perfect for runing multimedia and navigation but it dnt have Otg support which i need to attach rear view cam. I rooted it with kingroot 4.1 and installed root explorer. I have placed android.hardware.usb.host.xml and updated vx.core.hardwarwe.xml. now now i used all otg diagnotics and mounting apps but all are showing otg and usb host active but Linux kernel 3.10.0 (andoid 4.2.2) is not otg supported and no usb flash or usb cam is geting recognized by ellipsis 8. Is there any patch for kernal that will do the job? Wht should be next step??
