Priya,
I believe the SD card reader should have a status indication
mechanism that needs to be used for card detection purposes. If it is a
proprietary implementation then you would have to write a driver on Linux to
interface with the mechanism or get the related code from the vendor.

Subject: Unable the detect SD card after kernel boot up on DM6467
Hi,
I am working on a custom board which has TI Davinci DM6467 Processor running
Linux 2.6.10 as the host processor to which we have a USB2640 hub controller
connected on the USB bus. This hub controller has a built in SD card
controller. So basically this hub supports two USB devices and one SD card.
The problem I am facing right now is that if the SD card is connected during
kernel boot up, the SD card gets detected and also enumerated. After this I am
able to mount the SD card.
But in case I plug in the SD card after kernel boot up, the SD card does not
get detected when I insert it.
The USB devices like USB pen drive or mouse connected to the USB ports are
detected when they are hot plugged.
So how do I enable hot plugging for the SD card? Basically how do I enumerate
the SD card once the kernel is up and the SD card is hot plugged?
Thanks,
bkrpri
