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?.

Is there a list of functions that can be used with the GTab USB? For example: can I mount a digital camera as a USB drive?
Pretty much all storage devices work. People have had success with 3g usb adapter. Mouse and keyboard also work. I haven't tried printer yet.
Has any research been done with usb wifi adapters? I've searched but with no success as I'm sure the issue would be driver related.
The kernel controls what can and cannot be used via USB first.. If there is kernel support for your do-dad, you're good to go at least for the first step... after that, the rest of the Android framework needs to allow you to do something useful with the thing, which may or may not stop it from helping... or may require apps, or additional libraries, or pixie dust.
Right out of the box, if it looks like a HID (keyboard/mouse) or storage, something encouraging will happen on most of the g-tab roms, even the stock rom. If its storage but a format that's not supported by your kernel, you may need additional modules, or it may never work.
Everything else, who knows. Use a custom kernel, and get the source, and build one that supports what you want. Check for linux support - if its supported in linux, odds are way way better...
user mode usb driver support?
I would like to write a "virtual Control Panel" application to communicate with a propriatery device via USB. Under Windows XP, I wrote a device driver, DLL and C++ application.
Now I am sure the linux kernel does not support the proprietary protocol of my device. However I understand that some linux systems support user mode device drivers for USB devices.
Is this the case with Android 2.3?
If so, can a user mode device driver be written with the Android SDK?
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?
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.
I backed the MiiPC Kickstarter project. I have received the device. It is running Android 4.2.2, kernel 3.4.50. I am attempting to connect the MiiPC to my PC in order to use ADB. My PC does not recognise that the MiiPC is connected. I have been unable to locate a USB driver for the MiiPC. Are there any, for lack of a better term, "backdoor" approaches to make the connection?
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.
