Traditionally DMA does not support USB or CompactFlash. Right now I am designing a system that uses USB (or CF) and it needs to consume very light CPU overhead, something like DMA can help. I just want to see if anyone here knows about a solution that can do this type of data transfer.

How much cpu power does writing/reading from a cf card usually take? I know writing to my hdd is only like 1 or 2 %.

Yes, use a hard drive.
