Recently I have been working on generic eCos support for USB slave
devices (not USB host controllers, that is a completely separate
problem). This involves several new eCos packages. There is a common
USB-slave package which will largely handle standard USB control
messages and the like. This needs to be complemented by a
hardware-specific device driver. There will also be a higher-level
support package for USB/ethernet style peripherals. This code should
get released via anoncvs in the coming weeks. The current device
driver is for the on-chip USB device in the Intel SA1110 processor,
not the PDIUSBD12.

I believe the Philips web site provides various bits of example code.
Another possible source of information is the Cirrus Logic web site:
IIRC one of their evaluation boards (EDB7212?) had a PDIUSBD12 chip
and came with example code, I do not remember the details.
