>Description:
A USB HDD, which has a USB HUB internally, is not recognized with
ehci as follows:

ehci_pcd: change=0x20
ehci after reset, status=0x00001005
ehci port 5 reset, status = 0x00001005
ehci_open: pipe=0xc1912500, addr=0, endpt=0 (1)
ehci_alloc_sqtd_chain: start len=8
ehci_alloc_sqtd_chain: start len=18
uhub5 at uhub4 port 5
uhub5: vendor 0x0840 product 0x0090, class 9/0, rev 2.00/0.00, addr 2
ehci_alloc_sqtd_chain: start len=9
ehci_alloc_sqtd_chain: start len=41
ehci_alloc_sqtd_chain: start len=2
ehci_alloc_sqtd_chain: start len=9
uhub5: 4 ports with 4 removable, self powered
ehci_open: pipe=0xc194bb80, addr=2, endpt=129 (1)
usbd_setup_pipe: endpoint=0x81 failed, error=INVAL
uhub5: cannot open interrupt pipe

The root cause of the error is in ehci_open():

	case UE_INTERRUPT:
		pipe->methods = &ehci_device_intr_methods;
		return (USBD_INVAL);       /* <=== Here! */

Is it unimplemented?

The USB HDD works with uhci, not ehci.
