opencores.org USB 2.0

Hi,

I'm trying to write Wishbone-Avalon wrapper for USB 2.0-core from opencores.org, but I don't know how to connect DMA-signals: USB 2.0-core has some signals, which are not included in Wishbone standard (interrupts, power saving signals and DMA signals) and I no idea how to connect DMA's. Has anybody tried this core for Nios II?

Otherwise Wishbone and Avalon seems to fit each others without problems.
