I saw in BIOS EHCI handoff ( btw, do you what it does? ) and I also can disable legacy devices, except these two I didn't find any USB options in BIOS. FYI, I tried live Ubuntu and live Mint xfce and the results are the same, keyboard and mouse doesn't work. So I guess this is pure linux problem. I mean if everything works in BIOS, it should work also and outside them. Didn't try Windows yet. Thanks for the support.
