can read canbus messages between controllers, but not from PEAK device

Hi all,

I have set up a very simple CAN network with two SDC2160 controllers connected; a PEAK PCAN-USB adapter is used to connect my PC. I use rawCAN mode, 250 kbps, distances are much less than one meter, 120 ohm resistors at both ends.

The controllers happily talk to each other and I can see the traffic with PCAN-View on the PC. But any message that I send from the PC does not seem to reach either of the controllers even though "Listen Node ID" is set to "0" on both controllers. I must be overlooking something simple, but I have no idea what. Do you have any suggestions for me to try?
