As a follow up to my quest for a thunderbolt adapter for my P2 workflow in the field, I have purchased another adapter. This time, the Matrox MXO Thunderbolt adapter.

This adapter is a straight Thunderbolt to PCIe interface, not an Express34 adapter like the Sonnet Echo.

Of course, the MXO Thunderbolt adapter has one purpose, that is to interface an MXO2 to the Thunderbolt port. I am NOT trying to do that. I am trying to interface Thunderbolt to my P2 card reader, the PCD35.

I had successfully used another Matrox card in the past, a e34 to PCIe adapter, which worked great on my pre TB MacBookPro.

Alas, this adapter does not mount my PCD35 either. It may be a driver issue, but the Matrox tech support line has very long hold queues, over 2 hours, so I have not been able to speak with anyone regarding it. I expect that the conversation would go like this: “you’re trying to hook up what? We don’t make a PCD35. No, we do not support that.”

I think I will save myself the time, and go back to a firewire based PCD20.
