hi My system is Lite5200 with DENX Embedded Linux running on it.When I tried to enable my USB port to use my u-disk,
the problem occured. I have enabled USB support with 'make xconfig'. The reports are as follows: ******************************************************************** U-Boot 1.1.2 (Nov 12 2004 - 11:46:06)

It seems that the USB port has been detected.But the filesystem mounted unsuccessfully!(Mounting USB filesystem:
mount: mount point /proc/bus/usb does not exist)
Please give a hand! Thanks in advance!!!!!
