Thanks, Mark.
For some reason, the device isn't resetting properly when we try to attach it to the VM. You might want to try editing /etc/vmware/passthru.map to configure the reset method used for the device, and see if that helps. Brief instructions are at the top of that file. I don't know which reset method(s) will work with that device, so some experimentation may be needed.
Perhaps try:
1b4b 9123 d3d0 default
and try other reset methods (as listed in the file header) if that doesn't help.
Cheers,
