Device detection in android os
 

Hi Friends,
This is karun, Can any one tell me how device like SDIO is detected in ANDROID platform.
Thanks in advance.

depends...your devices/ROM would need to support UTG which is USB On The Go. If you doesn't support that, nothing you plug in will be reconized. Also, as for recognition, you have to remember that its striped down. it doesn't support all devices. mainly keyboards, mice, sdcard readers and such.

Thanks but can u tell me in driver prospective regarding buses ,how its going to intimate to kernel,how intrpt handled,how its related to user space etc..
