Kat any luck ?

One thing to be aware of if your already not,
is the compiler supplied with the cygnal kits is not
the full version but a limited edition.

Also its not cygnal any more but silicon laboritories.
Entering www.cygnal.com takes you to
http://www.silabs.com/products/microcontroller/

Came across another micro with usb the other day.
Bga only - pain.
Analog devices BF-535
They call it a embedded processor but its more of a dsp.
http://www.analog.com/selectiontable/ADSP-BF535P
http://www.analog.com/IST/SelectionTableProcessors/?selection_table_id=31

Also for anyone considering dsp
have a look at this
http://www.analog.com/Analog_Root/static/promotions/BlackfinGO/index.html

http://www.analog.com/processors/epProductPage/0,2542,BF533%252DHARDWARE,00.html
board comes out at Aus$150 (US$99) + p&h  from memec
not bad for a 600MHz dsp + 32MB ram

The bf-533 in the kit doesn't have usb support builtin.
(There is a lqfp chip version - runs 300MHz ).

The c\c++ compiler and ide is quite nice.
Basically visual studio 6 ide.
Compiler in the kit is executable size limited to
requires that the EZ-Kit be connected to the USB port
(like a dongle) once over the 90 eval period.
There is no time bomb.
