Connecting usb to uart device to android device >3.1

Question

I know that the latest android device with API>3.1 support USB host mode or USB OTG that allows you to connect a lot of usb devices like flash disks,mouse,keyboard etc. but can you connect any device that does not have common general drivers like USB to uart device,printers,cameras

I have linux drivers for these devices in source codes as .c files, So is there a way that I can build and install those drivers to an android phone and make the usb devices usable on the phone?

Answer 1

Never Mind ! I found a standard way for my device here It provides interface through native code and IPC and official library from manufacturer

Answer 2

To use linux drivers for android you have to compile your own kernel or kernel module. If you expect your app to be used by other people, this is not a feasible way.

For some low bandwidth USB devices it is possible to write user space drivers in java using the Host API. For USB-UARTs there is the usb-serial-for-android project that is implementing a user space driver based on this API.
