Yes, I already understood this.

Yes, and I understood this as well.

The converter adapter is working fine if I connect my ps/2 mouse and keyboard but it does not work when I connect the barcode scanner.
So to summarize, it works in the ps/2 port. But it does not work thru the use of the converter adapter.
Ah, some details...
Did you see see my closing comment - I'll requote it (strike 2):
Also, have you tried plugging in the desktop's keyboard along with the barcode scanner, like you would (I assume) with your dekstop ?
Why would that make any difference ?
Because the barcode scanner device is probably looking for the clock signal from the keyboard, so it knows how to set itself up, and be able to inject appropriately into the keyboard's data stream. From memory there were/are at least two keyboard clock speeds 6 and 8 MHz. Though I'd have to look that up, to be sure.
Have to go, I'll check back later this afternoon, or tonight..
