Hi, all

I am using ARM11 SoC and u-boot-2009.03 stable tree. EHCI HC is embedded in SoC.

In ehci_submit_root function, code is like this:

typeReq = req->request << 8 | req->requesttype;

switch (le16_to_cpu(typeReq)) { case DeviceRequest | USB_REQ_GET_DESCRIPTOR: switch (le16_to_cpu(req->value) >> 8) {

At the first call of 'usb_get_descriptor' for retrieving the root hub device descriptor, I think the first case should be matched.

But In my environment, le16_to_cpu(typeReq) is 0x0680. (request= USB_REQ_GET_DESCRIPTOR, request_type=USB_DIR_IN) and DeviceRequest | USB_REQ_GET_DESCRIPTOR is defined as 0x8006.

So the request failed and "Unknown request" printed out.

Do you think that I did a mistake for some byteorder stuff? I didn't define anything related with the endianess, like LITTLEENDIAN for the old OHCI HCD.

CONFIG_USB_EHCI CONFIG_USB_STORAGE CONFIG_CMD_USB are defined for my board config.

Thanks.
