Because you need a software app to switch the USB port to Host mode, you can just use a USB gender changer. A real host cable is only needed to trigger host mode on devices that detect a host cable.
But then, the host cables I got were only $0.99USD (including shipping) from a Chinese ebay store (plus a month or more wait time for delivery).
If you are in a hurry, you can make one (with no host cable signal) from a couple of other cables by cutting and soldering them.
We still need a USB mode switch software tool (perhaps we can adapt the one provided in the Nook Simple Touch forum at MR).
