I have also concluded that no Express card adapter will work with the shuttle, shame too, it is a nice box, got it to work on a Sager np8130 (HM65) and a dell m6600 (QM67), I think when looking at the Shuttle the best thing to to is look at the Wiki page on intel chipsets
http://en.wikipedia.org/wiki/List_of_Intel_chipsets
At the bottom of that page you will see the chip'sets with 6 Gbit/s, 2 Ports & 3 Gbit/s, 4 Ports, the sandy bridge chipsets, gen two with onboard usb3 seem to be stable for the Shuttle. This is just for sourcing into R3/4 have not done captures, thats a whole other deal. Anyways once you tinker with all the settings of the source and capture it will work on a laptop. Sucks though because with the m6600 it has the express card slot on one of the 6 Gbit/s, 2 Ports, and with an adapter that states it can do up to 5 Gbit/s.. but once connected the Shuttle is not even recognized.
The solution was to get a Matrox MXO2 mini into the express card thus offering a second 1080 source, got that working so both the Shuttle and MXO2 can mix with each other in R3.. BUT! the MXO2 has too much delay 1/3 to 1/2 a second, way to much for me.. the Shuttle is quite snappy, maybe a frame of delay.
Any one got the MXO2 or the Motu HD express to work good without delay, or at lease only a couple of frame???!!! thanks!!!
