usb receptables from old motherboard => gender changer => usb host cable?

[Timo Juhani Lindfors]

I tried this "USB gender changer" and the voltage levels seem to go
just about right:

normal pc usb port
==================

black GND
green 0V
white 0V
red +5V

freerunner as device
====================

black GND
green 0V
white 0V
red 0V

freerunner as host
==================

black GND
green 0V
white 0V
red +4.98V

However, usb devices don't seem to work. Even the simplest USB
extension cable with LED does not turn its LED on. Any idea how I
should debug this further? I am using

echo "host" > /sys/devices/platform/s3c2410-ohci/usb_mode
echo "1" > /sys/devices/platform/neo1973-pm-host.0/hostmode

from http://wiki.openmoko.org/wiki/Neo_1973_USB_host to turn host mode
on and the following rootfs and kernel:

Maybe the ID pin in the openmoko usb cable somehow causes trouble?
