SPI communication problem

Hi, I am trying to use this sd reader, this one:

http://www.geeetech.com/sd-ramps-breakout-for-teensylusanguinololu3d-printer-p-626.html

but i can't get it working in any way, I have tried with every lbraries, oficial one, sdhc one.... and with 4 different sd cards from 1gb to 4gb with any luck.

I would like to know if there is any way to know if it is a problem of my shield or spi port is not working.

Do you have logic analyzer to check if the communication is ok ? what target are you using? Did you update libraries to the latest revisions in all programs you testeD?

Lpc1769 Lpcexpresso working successfuly with every other peropheral. I don't have logic analyzer I was whiling for a way to report it via software. By the way, I have lpc812 max too if I can build any project as logic analyzer.
