Does what it says but probably not what you want,
Verified Purchase(What is this?)
This review is from: USB-A MALE TO PS2 FEMALE ADAPTER - USB TO PS2 (Electronics)
This is a passive connector that does the opposite of the adaptors you usually get with a USB keyboard or mouse to plug it into a PS2 motherboard, but unfortunately this doesn't mean you can plug an old PS2 keyboard or mouse into a USB port since a PS2 device will not normally support USB protocol.
It was my own fault for not realising this so I can't criticise the product itself, but I can't see what use this adaptor might actually have. It's so cheap that the mistake is no great loss.
