Hi all
     Have anyone come across the problem like that,once the kernel boots it print:
    usb 2-1: new low speed USB device number 3 using fsl-ehci 
    usb 2-1: device not accepting address 3, error -71 
    +++ hub_port_connect_change:udev->level :1 
    usb 2-1: new low speed USB device number 4 using fsl-ehci 
    usb 2-1: device descriptor read/64, error -71 
    usb 2-1: device descriptor read/64, error -71 
    +++ hub_port_connect_change:udev->level :1 
    usb 2-1: new low speed USB device number 5 using fsl-ehci 
    usb 2-1: device descriptor read/64, error -71

    It seems the usb cant register to the kernel.

I have seen something like this occasionally - it's usually a problem with the board's USB hardware. Do you have another board you can try?

Can you provide a bit more details, e.g. the BSP version, board, etc.
