Re: -CURRENT, EHCI, and the iPod

I have MFC'd the ehci controller
and I see it working there.
well, in general..
---------------------------------
    class    = bridge
    subclass = PCI-PCI
uhci0_at_pci0:29:0:        class=0x0c0300 card=0x80891043 chip=0x24c28086
rev=0x02 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82801DB (ICH4) USB UHCI Controller #1'
    class    = serial bus
    subclass = USB
uhci1_at_pci0:29:1:        class=0x0c0300 card=0x80891043 chip=0x24c48086
rev=0x02 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82801DB (ICH4) USB UHCI Controller #2'
    class    = serial bus
    subclass = USB
uhci2_at_pci0:29:2:        class=0x0c0300 card=0x80891043 chip=0x24c78086
rev=0x02 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82801DB (ICH4) USB UHCI Controller #3'
    class    = serial bus
    subclass = USB
none0_at_pci0:29:7:        class=0x0c0320 card=0x80891043 chip=0x24cd8086
rev=0x02 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82801DB (ICH4) USB EHCI Controller'
    class    = serial bus
    subclass = USB
--------------------------------------
ehci0: <EHCI (generic- USB 2.0 controller> mem 0xf7000000-0xf70003ff irq

evice 29.7 on pci0
ehci_pci_attach: companion usb0
ehci_pci_attach: companion usb1
ehci_pci_attach: companion usb2
usb3: EHCI version 1.0
usb3: companion controllers, 2 ports each: usbp usb1 usb2
usb3: <EHCI0(generic) USB 2.0 controller> on mhci0
usb3: USB revision 2.0
uhub3: (0x8086) EHCI root hub, cla{s 9/0, rev 2.00/1.00, addr 1
uhub3: 6 ports with 6 removable, self powered
---------------------------------------------

however I still see some problems that I am looking at..
e.g. sometimes teh kernel stops booting at the ehci probe.
(sometimes it gets past it), So I've more to do.
