keyboard emulation and ps2 port

Hi all,

I've already make a keyboard emulator througt USB with a PIC18F2455. It works fine.
Now, I would like to make the same thing but on a computer without usb port. Can I plug my PIC into a usb - ps2 adaptator and connect it to my computer??

Another Idea? Thanks in advance!
See you.

Fabe.

    I suspect nothing very special is happening inside the adapter ! it's just that the device that you see using it can communicate both in the USB and PS2 protocol's.
    This is all guesswork but my answer would be no - not as is.

    Have anyone got a solution to fix this problem??
    How can I make a keyboard with a PIC and without usb connection...?

    I have designed a PS/2 keyboard encoder using routines from Adam Chapweske's, here http://www.computer-engineering.org/ps2keyboard/

    Let me know if you need any help using these routines.

    it will depend on USB->PS/2 adapter's structure,
    if the adapter can resolve the USB protocol to PS/2 protocol , result will be ok,
    if only the wire connect, no thing will happend.
