i have written USB Peripheral Driver for ISP1583 & USB Mass Storage Driver for harddisk present in MP3 Player and it is working fine.
but i have to do more i.e.,when USB is connected to the host an USB icon should be displayed on the lcd of mp3 player & when it is plugged out the USB icon should go(not be displayed). for that i have to implement something in my driver so that i can inform the application about plugging in & plugging out.
has anybody has done this.
