P2020: device not accepting address

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Dear all,

First of all let me apologize if this question should be done in other
list. In that case, if anyone can redirect me I would be very
thankful.

We have designed a board based on Freescale P2020 in which we have
implemented linux-2.6.32.

Attached to the P2020 we have an USB3300 (which interfaces UTMI to
ULPI) and then an SSD with USB interface.

When we boot, we have the USB3300 in a reset state, and when we made
it leave this state and begin to work, we obtain the following traces.

I have explored the internet and have found some experiences of this
kind with different laptops... It seems that removing ehci or
resetting the device is sometimes the solution, but in my case
removing ehci is not an option.

The relevant configuration of the kernel (as far as I know) is:
CONFIG_USB_SUPPORT=y
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB_ARCH_HAS_OHCI=y
CONFIG_USB_ARCH_HAS_EHCI=y
CONFIG_USB=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_EHCI_HCD=y
CONFIG_USB_EHCI_ROOT_HUB_TT=y
CONFIG_USB_EHCI_FSL=y
CONFIG_USB_EHCI_HCD_PPC_OF=y
CONFIG_USB_STORAGE=y

I have also take a look to usbmon.txt and have obtained the following
traces with usbmon:

I am not an expert with USB, so I do not really know how to correctly
interpret this traces or what else to test.

Any clues?

Thanks
