It wouldn't work, at all.

You've got USB to db9 serial, to db25 female, back down to db9 serial. At this point, since the chain started life as a USB to serial adapter, this should be a functional serial port.

But then, it gets converted to PS/2 mouse. Then to AT keyboard, then back to PS/2 mouse, before becoming a USB port again.

That's not how it works.

You see, he should have just plugged the dongle directly into the usb port on the laptop.

    Do any of these adapters actually do any signal processing / transformation? I always assumed they were simply wiring crossovers. But I guess when the number of pins change there has to be an IC in there somewhere?
