rayman - the mini-b to mini-b should work. If those cables have 5 wires connecting each end, you can do what I did for my micro to host adapter.

Note - I now have both an N800 and N810 (Upped the dose to two tablets?), and only have the one modified for host mode sense mini B male to standard A female adapter and an original (unmodified) micro b to mini b adapter like the one that I modified for host mode. I will probably do more of the mB-AF adapters.
