The trouble with the usbWigglers is that they don't work with 
CodeWarrior - we are trying to test out both!  We've ordered one of the 
P&E debuggers, so we'll see how it goes.  After checking that we've got 
an appropriate chip for the project, we can decide which toolchain to 
use (CodeSourcery or CodeWarrior), then if necessary buy a better and 
faster debugger.

Thanks for you advice,
