Hi Magellan,
after several weeks of testing/hacking, I couldn't make the belkin card work. But my socket v2.5 Rev. G, after the same amount of hacking effort, works nicely and fits better in the cf slot.
I'd suggest:
1) forget about the belkin card
2) go into the how-to section, and folllow the excellent bluetooth instructions to get the socket card working
3) post any further problems you may have regarding the socket card
P.D.- before trying point #3 above, go to the nearest supermarket and buy an extra-large luck & caffeine bottle :-)
