VTI SCP1000 and Proto USB board

Now this problem is beyond my logic.
I am trying to use SCP1000 to get pressure and temperature. When I connect SCP to Propeller Demo Board, everything works great, but where I use Propeller Proto USB I get nothing, no reading from pressure sensor no temperature. Hmmm, I checked 3 different sensors, tried 2 different Proto Board and still nothing, again I returned to Demo board and it works. I use the same software, one more thing I tried different pins on Proto board and guess what - nothing, no reading
Does that make any sens to you??
Did I lost my mind
Thanks like always

I don't know if this is your problem, but it had caused me trouble on more than one occation.
Are you using an object from the OBEX? I have a SCP1000 right in front of me. I could give your code a try if you'd like. (I headed to bed now so I wont be trying it until the morning.)

If you want to try code, I used this object http://obex.parallax.com/objects/408/
Give it a trial if you can and see if it works. It works on my Demo borad does not on proto board - very strange
Thanks

Pins from VTI SCP1000 must be connected in order.
In my case
SCK - 0
MOSI - 1
MISO - 2
CSB - 3
DRDY - 4
Order is important, not an absolute numbers, so the setting above was for my Demo Board, in my final design pins go : 8 , 9, 10, 11, 12 (SCK, MOSI, MISO, CSB, DRDY).
If I tried change the pin order with changing pins assignment in software ( I used object from http://www.parallax.com/Store/Sensors/PressureFlexRPM/tabid/177/CategoryID/52/List/0/SortField/0/Level/a/ProductID/591/Default.aspx ).
It was acting strange, f/ex giving only one reading without updates, or simply not showing anything.
Hmm so interesting, the problem was not Proto Board, simply pins that I used (available were not in order).
Well, I am moving foreward and probably will get stuck on something else, but I am sure that you guys will be able to help
