Has anyone tried use a powered USB adapter cable with a USB card reader?

I thought I read in one of the forums (can't remember which one) that you could get the N800 to recognize a external HD by this method, so a USB card reader should work to.

See link for how to make a powered USB adapter cable.

If you search the forums, you should find alternate methods too.

Seems easy enough to try.
