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.
Any help woule be preciated,thanks.
Best Regards
