Tracing Using ST-Link V2 and Ac6 System Workbench

The processor is an STM32F373VCT. The emulator probe is an ST-Link V2 iso.

I have on the board JTAG connections to all five of the processor's trace pins (CK, D0-D3). In the Ac6 System Workbench's Trace Control window I see that when I have a debug session in progress there is the message  "Tracing is not supported." Is this because the DBGMCU->CR register is left in its default state? If I set TRACE_IOEN, and TRACE_MODE bits in this register would tracing be supported? Or is tracing not supported in ST-Link V2 hardware?
