Hello,
I am currently using a Madiface with express card connected to a SONNET adaptor. It has been working for me before, however it is now not being recognised on boot up. I have also noted reliability problems with my older Macbook 17" where i had the same problem and it was a case of shut down/ boot up several times until it was recognised by the machine. I have the latest drivers (hdspe_x86_304.zip) and i am now at a loss as to what is causing this unstable performance.

Macbook Pro 15" Retina 2.7GHz i7 16GB RAM

Thanks in advance for any help

PPower
