USB host for 9g45

VENKATESH S

I have configured USB Host controller of AT91SAM9G45 board. I have enabled USB Flash drive 0 in
File_config.c. OHCI is supported in our processor. Hence i have selected OHCI as USB host0
Controller interface in usb_config.c file.

When I call finit("U0") it is returning value 1. Calling usbh_init(0) returns 1.
When i call usbh_engine(0) and then read status through usbh_msc_status(0,0), status always
returns zero whether i connect usb pen drive or not.

What event will happen when a usb device is connected in host port ? The usb pen drive is
getting power.(As i configured power gpio pin) How do i debug the application.

I have taken LPC RL-USB host sample project located in this keil path as base project :
E:\Keil\ARM\Boards\Keil\MCB1700\RL\USB\Host\MSD_File.
