Winy,
Are the USB modules loaded on your system. i.e. usb_storage. Can you please provide the output of lsmod on the board when it has booted up?

This board is flashed with u-boot 1.2.0 In the u-boot1.2.0 source code, in .doc/ README.usb document, it is mentioned that "The USB (at least the USB UHCI) needs a frame list (4k), transfer descriptor and queue headers which are all located in the main memory. The UHCI allocates every millisecond the PCI bus and reads the current frame pointer. This may cause to crash the OS during boot. So the USB_MUST_ be stopped during OS boot. This is the reason, why the USB is NOT automatically started during start-up. If someone needs the USB he has to start it and should therefore be aware that he had to stop it before booting the OS." Also, the configuration parameters to be used are, CONFIG_CMD_USB enables basic USB support and the usb command CONFIG_USB_UHCI defines the low level part .A low level part must be defined if using CONFIG_CMD_USB CONFIG_USB_KEYBOARD enables the USB Keyboard CONFIG_USB_STORAGE enables the USB storage devices I have tried enabling above parameters, but the code was still unable to detect the usb storage device. It would be really very helpful, if someone could give me hint to the solution, as to which files and parameters should I manipulate. Thanx in advance for the help !!
