I’ve used/tested the Intensity Shuttle on various different hardware. The main problem I came accross was when using any USB 3.0 controller other than the NEC/Renesas (I’ve even tried the Fresco Logic FL1009 and it failed miserably).
Also power saving technologies can prevent the Shuttle from working. On Intel P67, Z68 and X79, enhanced ‘C’ states (C3/C6/C7) must be disabled. On AMD 890/990FX, with a Phenom II CPU, C1E must be disabled, with an FX CPU it can be left enabled. Lastly, PCIe link power saving must be disabled in the Windows 7 power options.
Getting the Shuttle working on a Laptop is tricky. A USB 3.0 ExpressCard isn’t going to have enough bandwidth, BlackMagic’s own support page states: “ExpressCards for notebooks are not supported and will not work. The bandwidth they currently support is not suitable for Intensity Shuttle, UltraStudio Pro or Pocket UltraScope.”
