MouseWarrior - Ways to move the cursor

Pointing devices come in a wide variety. The once dominating opto-mechanical shutter wheel mechanism is now sharing the market with the optical sensing devices with no moving parts. Special applications use force sensing and other technics.

To add to the variants there are two major interfaces: USB and PS/2. And two interfaces that are loosing significance but are still present in some markets: Serial and ADB.

The MouseWarrior family of pointing device controllers covers a large part of the pointing technologies in use and all of the interfaces. All of the MouseWarrior chips do offer USB and PS/2 in the same chip and MW20 chips do also have ADB and serial interfaces.

Selecting between interfaces on the MouseWarrior can be done by plug selection. There is no need for different circuitry, though parts my be left out if certain interfaces are not in use.-

In manufacturing this gives you three options:
Put everything on the PCB and ship with either plugs or a multi connector cable.
This allows the user to select the interface and reduces your production and warehouse stock to one type.
Put everything on the PCB and add the appropriate cable as the last step. This does simplify your production and increases parts commonality a lot but leaves your distribution the same.
Place components for only one interface on the PCB. This still does increase parts commonality a lot and it optimizes the per unit production cost. For high volume this may be the way to go.

Currently there are standard off the shelf MouseWarrior chips to support classic opto-mechanical devices, force sensing, and optical tracking.
