Cant get two HRAP 2 to work on ps3?


I have two HRAP 2 SA connected through two Real PS2/PS3 convertors to a slim PS3, but the problem is i cant get them to work at the same time. Tested both the convertors individually and they are working fine but when they are both connected and i press the PS button on one of the convertors and its recognized then pressing the PS button on the other wont do anything and the 4 lights keep blinking.
