Hi,

  I finally got -CURRENT to install on my laptop as of 2003-03-25 and have 
been playing around with the acpi code trying to figure it out.  One of the 
main problems is to get my USB bus to wake up after a suspend, currently all 
the USB devices dies when suspended and resumed.
How can I tell the USB PowerResource to turn on?  I've been able to access 
devices that have a HID and create drivers for those, but I don't know how to 
access resources with only _ADR addresses.  The USB portion of my acpidump 
below:

        Device(USB_) {
            Name(_ADR, 0x00020000)
            Name(_PR0, Package(0x1) {
                USBP,
            })
            Name(_PR1, Package(0x1) {
                USBP,
            })
            Name(_PR2, Package(0x1) {
                USBP,
            })
            PowerResource(USBP, 1, 0) {
                Name(RSTA, 0x1)
                Method(_STA) {
                    Return(RSTA)
                }
                Method(_ON_) {
                    Store(One, RSTA)
                }
                Method(_OFF) {
                    Store(Zero, RSTA)
                }
            }
        }

Thanks,
