Hi

   I am tring to use keyboard and storge device on u-boot (beagle board).

I have added/enabled below configuration in "include/configs/omap3_beagle.h"

*==============================*/
/* USB configuration           */
/*==============================*/

#define CONFIG_USB_KEYBOARD             1
#define CONFIG_MUSB_HCD                 1
#define CONFIG_MUSB_UDD                 1

#ifdef CONFIG_MUSB_HCD                          /* include support for usb host */
#define CONFIG_CMD_USB          1               /* include support for usb cmd */

#define CONFIG_USB_STORAGE      1               /* MSC class support */
#define CONFIG_CMD_STORAGE      1               /* inclue support for usb-storage cmd */
#define CONFIG_CMD_FAT          1               /* inclue support for FAT/storage */
#define CONFIG_DOS_PARTITION    1               /* inclue support for FAT/storage */

#ifdef CONFIG_USB_KEYBOARD                      /* HID class support */
#define CONFIG_SYS_USB_EVENT_POLL       1
#define CONFIG_PREBOOT "usb start"
#endif /* CONFIG_USB_KEYBOARD */

#endif /* CONFIG_MUSB_HCD */

   I have connected the device to USB Host but unable to detect.

OMAP3# usb�start
(Re)start USB...
USB: scanning bus for devices... No USB Device found
scanning bus for storage devices... 0 Storage Device(s) found

Any one has tried this on beagle board.. Is it correct way / Approach ?

Have you connected the devices through a mini-A plug ? (note that mini-A is different than mini-B).

Dear Ajay,

The beagle board has 2 type of usb connector on the board. 1) 4 usb port (Type A connector) communicating with "usb_ethernet hub (9514) ---> usb transiver (3320) ---> omap3 processor". I am tying to connect usb-kbd on one of this port i.e again Type A (4.5 mm x12.0 mm) connector. 2) mini-B connector on which i can not connect usb-kbd.

Regards

Atul,

Uboot supports usb otg port (musb) only and the config you have enabled is also for MUSB OTG. You can use musb port instead for your testing.

Dear Ajay,

You mean i need to use a converter from Type A to mini-B and it should work fine ??

But in my custom board i do not have that facility. I need to use usb-ethernet hub for my custom board. can u guide me to make it up with that??

I have got some patch and support in u-boot -2011.06. http://lists.denx.de/pipermail/u-boot/2011-November/107993.html

but hang after msg "USB clocks enabled" .

Atul,

You need a converter to use on OTG port which doesn't seem to be available on your custom board and so you have only option to use sta-A connector on HSUSB (EHCI) ports.

I have not tested or used ehci uboot patch and so better send a mail to uboot community for the issue you are facing.
