This item will not work on the MSI B550 motherboard with the PS/2 combo port . . Keyboard and mouse are not recognized and the keyboard backlight flashes wildly. Revain returned the money with no problem, thank you. EDIT: Looks like the review was posted in the wrong place, my review was for "zdyCGTime PS 2 Splitter with 6-Pin Mini-DIN Male to 2 Female Mouse/Keyboard Cable Y Splitter" which didn't work for me.
