USB Keyboard on Amstrad CPC

[DoctorCPC]

Hi dear friend,
Im using ps2 mouse adapter from Bryce.  But i want to use USB keyboard (specially) and USB mouse. How can l do it? My computer system is using 4 port usb KVM switch.  PC, Mac Mini, Amiga piStorm use one vga monitor one USB mouse and one Usb keyboard but Amstrad CPC only use 1 vga monitor. And ps2 mouse didnt adopt this system. Therefore i want to wear usb keyboard and mouse on Amstrad CPC.

My PS/2 Mouse adapter works with USB mice that have a PS/2 compatibility mode (most older USB mice) if you use a PS/2 to USB adapter.

I don't think this was done already ... you would have to convert the USB Protocoll and then go directly to the 40027 (?) chip in the CPC ... Personally I never seen any hardware that can do this ....

I'd suggest a microcontroller which plugs into the keyboard header would be the way to do this. USB stuff is outside my sphere of knowledge though.

@gerald did a keyboard interface, but I don't remember if it's PS/2 or USB device. And if it's PS/2 whether it would work with a PS/2 to USB adapter.

I've been looking into it but I don't understand much. I'm also looking specifically for the Amstrad CPC 6128 computer. It doesn't matter if it is PS2, USB can be used with the adapter.
