Need adapter to plug USB keyboard into PS/2 port.

[bupkus]

I have a numberpad keyboard that's USB and I'd like to plug it into a PS/2 socket.
I used a mouse USB>PS/2 adapter but the bios failed to boot.

You do know that USB and PS/2 aren't directly compatible, right?

You can't do that, the Keyboard / Numbpad needs to support PS/2 w/ the adaptor (it requires hardware support, IE another chip inside the keyboard) to function properly. Unless you have a USB to PS/2 Converter, not just an adaptor your out of luck.

If you read the OP you'd see that's what I did. The bios reported "no keyboard present".

ok, I lied. I haven't got a keypad yet. I ran the test using a keyboard I got at newegg by Lite-On model no. SK-6715. I need a keypad but hope to get a USB model with adapter as the PS/2 models are drying up and very expensive, case in point

I can't say if these are any good or not, but you need one of these:

USB to PS2 Adapter - note different ones for keyboards and mice

 

[bupkus]

Thanks. I didn't realize a different adapter was needed for the keyboard than the mouse.

Weird the Logitech USB keyboards works with PS/2 with just a small plug adaptor

 

[bupkus]

When you say "small plug adapter" are you saying you used a "mouse" adapter? As Varun's link points out, there are adapters for EACH the USB mouse and keyboard.

Even though the PS/2 sockets for the kbd and mse are the same, the PINOUTS are NOT... PS/2 to USB adapters may be brand specific. I think the ones you see for sale around are just some of those Infinite profit items (adapters left over from sold kbds/mses) anything divided by 0 equals infinity.

.bh.

It was designed that way. It costs extra to support both standards. many (most?) usb kbs are usb only, and need a usb to ps/2 converter, not just one of those adapters.

Mice are the same way, some support usb and ps/2 with just the plug adapter. Others dont and youll need a converter.

Look on the bottom of the mouse or kb, it will usually tell you. if it doesnt specifically say UBS-PS/2 youll probably need the converter, not just the adapter. And they are different, usually theres a mouse or kb icon on the adapter itself.

USB and PS/2 are different
you cannot just use a USB-PS/2 adapter and convert your USB device to PS/2
Unless the device IC controller chip support both USB and PS/2.

if you have a PS/2 mouse and you wanted to convert it to be able to use on USB port.
then you will need a PS/2-USB converter with a built in chip in the cables. it will actually
convert the PS/2 code to USB.

Where can I get a USB to PS/2 "converter". I just got this Dell keyboard:

I tried to use a purple, generic keyboard USB to PS/2 adapter, but my computer would give a boot error saying that it couldn't find a keyboard. I guess I'll try one of these "converters" you guys speak of, but where can I find one?

I have been looking for a USB TO PS2 keyboard converting thing forever. I tried some, none of them works. I thought it should be as easy as a USB/Ps2 mouse converter.
