Hello
I've got my hand on a BEISTA K107, a low end Android tab with Android 10.0 on it.
I'm trying to setup a photobooth but the tablet do not detect my DSLR when I plug it in USB. The tablet is supposed to be OTG compatible but It seems that it's not usb host compatible
Any idea how to correct that ?
I've try rooting it without success
@zeph
Support for USB host and/or USB accessory modes are ultimately dependant on the device's hardware, regardless of Android platform level.

I have an Ainol Novo 7 Paladin tablet running android ICS 4.0.3 (rooted) that I want to use in one of my projects. And I need it to communicate with an arduino - one with FTDI or prolific PL2303 serial interface. Now I know that the Paladin should work as an USB host but I need something more. I need an high level Java library that can use this serial interface. I've worked with rxtx on a desktop machine before and that is the most complicated that I would like to get. The main reason is that I simply don't have enough knowledge to write myself an serial driver. I just need a simple character based two way communication.
I've found this http://slickdevlabs.com/slick-usb-2-serial-library/ but I don't think that it will work for me - at least the test application doesn't since the Paladin has an Ingenic JZ4770 CPU that isn't ARM based. And the second problem - I don't like the price.
So I have made an USB OTG cable that is working - I can connect a mouse, keyboard, usb drive,... . Getting the serial interfaces working is another problem. When I plug the arduino with an PL-2303 controller to the tablet I get this (with dmesg):
Code:
USB AS HOST MODE
...
hub 1-0:1.0: unable to enumerate USB device on port 1
usb 1-1: new full speed USB device number 82 using musb-hdrc
usb 1-1: device v067b p2303 is not supported
we are entering usb_match_id!!!!!
Simillar with the arduino with FTDI controller.
As far as I know android should have the drivers for the PL-2303 and FTDI chips included. So any ideas?
Dear All,
I wanted to know if USB Host mode/On the Go (OTG) on for Samsung devices?
cos as far as i have seen, unless you modify kernel and use an app OTG doesnt work with other devices.
I have a tablet (HCL ME U1 - Version: ICS), which has normal USB/Mini USB, but the USB Host mode is not enabled on it. i was wondering how do i enable it ?
the other option is to buy a tablet which is OTG enabled, but as far as my knowledge, only samsung galaxy tab has OTG.
kindly help me out with information

I am quite interested in usage USB host ability on my china no-name tablet based on Allwinner A13 CPU. I'd like to use it as GUI front-end for my embedded project with STM32F4 ARM microcotroller. So far I use laptop as the GUI for this device. STM32F4 is connected via USB as a vendor-specified device. I use WinUSB library on laptop to enumerate connected device and to open endpoints.
I'd like to use tablet instead of PC. So I looked to the USB host API on Android and tried to enumerate devices. However I couldn't enumerate any device - includes mouse or flash drive, which works perfectly in the system, but getDeviceList from UsbManager returns emtpy list.
I installed USB Host Diagnostics application and run a test. All results are yes, only items "Claims support" and "Device detected" in Android API shows no. But there's an item "Device detected" in Rooted API, which is yes.
I'm quite new to Andoroid developing. What is Rooted USB host API? How can I use it? Thank you for your answer.
Can I use USB host to interface with an Arduino in CM11? This is very important, and if it does not happen, can somebody PLEASE come out with a patch; this is for school, and I need it soon.
AFAIK, none of the CM7/9/10/11 ROMs to date has support for USB Host for any kind of USB devices.
FWIW CM10.x/11 builds for the Nook HD/HD+ do support USB Host for some common types of USB devices (e.g., flash storage).
I am working on a project that requires me to setup a windows pc as an accessory in order to communicate with an android phone via a USB cable. After studying the ADK(ANDROID DEVELOPMENT KIT), it seems that you must have micro-controllers endorsed by google which supports aoap(android open accessory protocol) to communicate with the Android phone. However, my project requires me to establish communication between PC and ANDROID via a USB cable without a micro controller. Also i would like to know how to program such an application,what software should i use,what languages do i need to know? What should be step 1?.
