Codewarrior setup with USBTAP - USB open failure

I'm trying to set up a USBTAP to use with Codewarrior.  The host is FC6, and the target is an MPC8349.
 
I've been through various settings including CW Preferences, Debugger, Remote Connections.
 
Having selected CodeWarrior USB TAP, interface type USBTAP, I have verified it is configured
for CCS EPPC Protocol Plugin, USBTAP. 
 
Then select Debug, Connect, a msgbox pops "CCSProtocolPlugin::Could not connect to the requested core #0.
 
But the real story is in the protocol log - Error message:  USB open failure
 
Having confirmed the USBTAP is enumerated in /proc/bus/usb/devices
Bus=05, Vendor=15a2 ProdID=50b3
 
I then visit /etc/hotplug/usb.usermap and usb/usbtap
 
What isn't clear is how the USB device is detected by CodeWarrior and I suspect this is where
things are failing.
 
In usb/usbtap there is a reference to DEVICE=/proc/bus/usb/BBB/DDD
but there is no such device in /proc...
 
so I'm puzzled how to set this up.  Is there a downloadable USB driver module for USBTAP?
I've checked ccs/bin/ccs.cfg but not much to go on there...
 
 
Thanks in advance!
