I am using am335x board.USB device is detected when it is inserted while booting up the board. after the board is booted up, i unplug the device and is inserted again,it is not detected.usb driver switches off the vbus session when a device is disconnected from its port.every time i need to start the session using the command "echo F > /proc/driver/musb_hdrc".How to make it auto detect? If anyone has faced this problem,please post reply.

If faced the same problem. It seems that when you use ULPI mode, starting vbus does not work. Have a look on a newer kernel in file drivers/usb/musb/omap2430.c When an USB_EVENT_ID got notified, you should turn on vbus independtly of the mode your otg is working.
hope that helps.
