I am using Micromax A110 with Custom Rom (Android 4.2.2). I have installed usb host controller it recognize my mass storage device also i can mount to specific folder such as /mnt/sdcard/ehdd but this folder shows nothing in ES file explorer but i can see all contents in some root explorer where i found this folder contains only owner permission not user/group permissions, i tried to apply user/group permissions but i am failed with a message "permission change was not successful"
I have a problem with my elephone P8 with custom rom 4.2.2 and usb otg connections.
My phones doesn't see any mass storage device instead it works with usb device.
On usb host controller into the info I read "S3C USB host driver NOT found" and "Root hub present, USB Host mode is active"
How can resolve my problem?

how to enumerate USB device without using USB Host API
I developed one app to read data from USB device. I used USB Host API. It works fine on Nexus 7 tablet.
But I need to use it on pcDuino3. Android 4.2.2 OS is installed on that. But my app does not recognize the USB HID device on pcDuino3. It is unable to enumerate the device connected.
I used your app. It recognizes the USB HID Device and enumerates.
Where can I get source code for your app? Which API you used to detect attached USB device?
Is there a way to manually activate USB host mode?
My Samsung tab pro recognizes HDDs and keyboard with a USB otg cable,
but I would prefer carrying one less cable over automatic host mode detection.
Currently I use a small piece of aluminium foil to short-circuit pins 4-5, but that is a rather dirty and risky solution.
Hlw I have a problem. My phone is Micromax bolt D321 which is rooted and support otg usb.
I tried to connect pendrive but it won't show... I used stickmount and usb host controller also didn't helped me.. Usb controller shows “S3C USB Host driver not found”.what does it mean? Or I have install a kernel that supports pendrive... Where can I find it... Plz help me..
