Hi,

You can use the USB 2.0 function core with the UTMI phy module from
the USB 1.1 core project if you want to use it with a 1.1 phy (I've
tested this on actual hardware).

I'd recommend using the 1.1 core though as it's smaller, and appears
to have fewer bugs atm.

I'm using the 2.0 core in a product at the moment and it took quite a
few changes to get it working properly, but I've never used the 1.1
core.
