I was trying to get EHCI running on sequoia board (ppc440epx).

 

I'm getting the following message when issuing "usb start" .

 

Cannot enable port 1 after 5 retries, disabling port. 

Maybe the USB cable is bad?

Cannot reset port 1!?

1 USB Device(s) found

                Scanning bus for storage devices. 0 Storage Device(s)
found

EHCI works fine under operating system (a customized NetBSD). This is the
configuration I'm using,

.

#define CONFIG_USB_EHCI

#define CONFIG_USB_EHCI_PPC4XX     /* added ehci-ppc4xx.c similar as
ehci-ixp4xx.c */ 

#define CONFIG_EHCI_DESC_BIG_ENDIAN

#define CONFIG_EHCI_MMIO_BIG_ENDIAN

 

Has anybody tried sequoia?
