Manufacturer description

The StarTech.com GC46FMKEY is a replacement USB-to-PS/2 keyboard adapter for the specific situation retro builders run into constantly: a working keyboard, a motherboard with only a purple PS/2 port, and a lost dongle. This StarTech adapter restores that connection, letting a dual-mode USB keyboard talk to a PS/2 header on a vintage tower, a KVM switch, a rackmount console, or a BIOS-era system that never enumerates USB input. One thing to be clear about before you order: this is a passive pin-remapping adapter, not an active protocol converter. It only works with keyboards that are already…

Frequently Asked Questions

Will this work with any USB keyboard?

No. It only works with keyboards that are both USB and PS/2 compliant. If your keyboard originally shipped with a similar adapter, this replacement will work; if it did not, this adapter will not make it function.

How do I know if my keyboard is PS/2 compliant?

The reliable test is whether it came with a comparable USB-to-PS/2 dongle in the box. StarTech notes that keyboards shipped with a similar adapter are the supported case; otherwise check the keyboard manufacturer's listing.

Does this adapter also work for a PS/2 mouse?

No. This is the GC46FMKEY keyboard adapter specifically, described as a USB keyboard to PS/2 adapter. Mouse signaling uses different pins, so pick a mouse-specific or combo adapter for that.

Do I need to install drivers or software?

No. This is a passive pin adapter with no drivers, no software, and no power connection. Plug the USB end into your compliant keyboard and the PS/2 end into the computer's keyboard port.
