ps3 keyboard and mouse help

[Hardwire]

i play on the pc just to state that but any way when i try to play on the ps3 my mouse goes haywire and starts jumping is there any way to fix that (logitec g5 mouse 3k dps settings)
i guess what im asking is has any one found a good setting on the ps3 to make the keyboard and mouse feel rigth and not like a controller

[Hardwire]

just to add incase any one needs to know. I have a kvm switch that i use to keep my kb&m plugged into my ps3 and pc

any way thanks for the help in advance
