More info.
there are 3 USB connectors on this board
Host 1 - SIE1a
Host 2 - SIE1b
Peripheral 1 SIE2a
At the moment I do nto care about Peripheral 1.
I am virtually certain A0 and A1 are not switched.
with no USB devices plugged in
The status port is returning a value of 0x30 if I read it
immediately after iomapping the device.
It returns a value of 0x20 after calling c67x00_ll_init() and
c67x00_ll_hpi_reg_init()
The instant request_irq() is called before a single subsequent line
in the driver executes c67x00_irq() is called.
at that point c67x00_ll_hpi_status(c67x00); returns 0x20
the remainder of the interrupt handle is called and the status
changes to 0x0 - and remains there.
Howevr USB interrupts continue to occur until the kernel gets ticked
and turns them off.
