Many PS2-USB "converters" are really just "adapters" that actually rely on the keyboard to do the heavy lifting internally. These do not work at all. It sounds like it has gotten better but it used to be quite hard to get an M working. Of course these isn't much(any?) other ~40 year old PC equipment that is this easy to get working.

> I've been told that not all PS2-USB converters work.
True converters do. Those that don't work are just connector adapters relying on the mainboard to recognize that a PS/2 device is connected although on a USB port. To be sure you get a working adapter, never buy single port ones as they often contain just connection wires. All converters I tried with dual PS2 port, to be used with mouse and keyboard together, contained a real protocol converter and worked flawlessly on all PCs. An image search for "ps/2 usb" returns may examples of the two converters types.
Beware that the Model M draws more power than USB is allowed to supply. I've never heard of this being a problem in the real world, but I always plug my model M into a powered hub to ensure there is plenty of power available.
