Somebody in the thread at some point said:

There are two parts to host mode on Freerunner, logical and power. You
have found the power one which enables 5V @ 500mA out of the USB socket
(so you don't need a battery hub).
What you're missing is the bit that sets logical host mode in the USB
peripheral in the CPU:
~ echo host > /sys/devices/platform/s3c2410-ohci/usb_mode
This makes it "do the host thing" down the USB socket and enumerate your
WLAN device, etc.
