Surprisingly works well.
At first, my dell ps2 keyboard did not want to fit their plug, but it does fit, took some force, then it slid together fine. The inner rectangular alignment pin was bigger on the Dell keyboard than the slotted hole in the adapters plug. Looking at other keyboards, their rectangular pin is smaller, so DELL did something funny.
Testing on Mint 18.3, at first worked from a cold boot, seeing the drivers have to load? Then did not work on a warm reboot, saw a message saying could not configure device, then after that it works every time hot or cold boot-rebooting.
It does not work in the bios settings, does that make sense? Otherwise it is nice as I can use a nice ps2 keyboard I have.
This one has an active chip. The not working in bios for me is not a problem as the PC is in a boat at the end of a 20 foot long usb cable. I can always plug the PS2 keyboard into the ps2 mb port at the boat. I ran a 16foot usb wire to a usb hub up at the helm, and it was simpler to just use one wire for mouse, keyboard, gps, whatever is needed at the hub. etc...
