Well, Dev give me the hint to fix the problem. I already had configured the DMA transfer speed to 5 mb/s The thing was a jumper on the host (Ultrastor 14F) Jumper Block 13, 3-4 was OUT, wich means Host Adapter initiated sync negotiation. It has to be IN, wich means target initiated sync negotiation . And that was all the thing.
