--- Comment #8 from gyhor@gmx.de 2012-01-05 01:58:26 PST --- I can confirm that. My Setup is a Sony VPC-Z21 (detail: VPCZ21C5321B) with the external PMD-Station. The network, usb, diskrive are working. Only the graphic card refuses to get to work.
I am not sure, that theproblem is that the card is connect via LightPeak/Thunderbolt.
