CW/TAP: CCS Protocol Plugin: Error reading memory [connection refused]

I'm unable to connect to my target (MPC8280) at all using CW TAP with CW for PowerQUICC 8.8 (as recommended).  I'm using the USB connection.  When I try using Flash Programmer or HW Diagnostics, I get errors like:  "Read failed...Details:  CCS Protocol Plugin:  Error reading memory [connection refused]". 


Could I possibly have the wrong USB driver?  It's using usb8023.sys (Microsoft).  I haven't checked the JTAG connector signals, but I'm assuming there's only one way to do that, and I'm told it works with the Green Hills emulator. 


Any advice?  Thanks.
