Hi all

I am using hawkboard which is based on OMAPL-138 platform.

I am trying to read from usb storage device from the u-boot.

I have following things already enabled in u-boot

/include/configs/da850evm.h

#define CONFIG_USB_DA8XX /* Platform hookup to MUSB controller */
#define CONFIG_MUSB_HCD

#define CONFIG_CMD_USB      /* inclue support for usb       */
#define CONFIG_USB_STORAGE     /* MSC class support */
#define CONFIG_CMD_STORAGE     /* inclue support for usb       */
#define CONFIG_CMD_FAT      /* inclue support for FAT/storage*/
#define CONFIG_DOS_PARTITION /* inclue support for FAT/storage*/
#define CONFIG_SUPPORT_VFAT     //使能FAT32文件系统的支持
#define CONFIG_SYS_DEVICE_DEREGISTER
#define LITTLEENDIAN            //定义数据为小端模式

When I connect U-Disk by mini-A plug Cable to usb port, run "usb start", result

usb start
(Re)start USB...
USB: scanning bus for devices... New Device 0
usb_control_msg: request: 0x6, requesttype: 0x80, value 0x100 index 0x0 length 0x40
usb_new_device: usb_get_descriptor() failed
No USB Device found
scanning bus for storage devices... 0 Storage Device(s) found

I donnot kown that I ignored what?

Does not anyone know how to solve？

I confirm

1. VBus is power on

2. miniA cable

I feel this problem should be simple, but it is not resolved.

Thanks!
