USB 2.0 device controller core Status on Opencore

Hello Sir,

I  am interested in using the USB 2.0 Controller core in
Opencores.org 
called usb_funct project and am seeking general feedback
from anyone 
that has implemented it in an FPGA or ASIC.

Appreciate your feedbacks on any known issues and whether
the core 
will work or not in general. I will not use it for
production but rather use 
it to test my high speed PHY devices so I expect the main
datapath to 
work. Can please you share with me some experience you have
with this 
core via email?

Thanks a lot,
Gordon
