Your senses are well tuned (Linux version 2.4.19-rmk7-ds3-mw1). I'd happily
switch to 2.6. With joy! If only it would run on my processor (Intel
XScale IXP425). Technically the kernel will run, but none of the on-board
devices work due to some feet dragging by Intel and MontaVista on getting
some micro-code issues ironed out for 2.6.
/proc/ioports is not real helpful, /proc/iomem and /proc/pci are slightly
more helpful. From the /proc/bus/usb/devices output (below) I can get to
the bus number (3 or 4) on the topology line (T:), but I don't _think_ this
corresponds to the PCI CardBus number (1 or 5) and it also does not help me
understand which device /dev/usb/ttyUSB0 (for example) is hooked to. I have
at least 4 if not more usbserial ports available and they tend to bounce
around in their /dev/usb/ttyUSBx mapping.
Are you willing to provide any more guidance? Or did I just overload you
with information? :-/
