Identical bays in the keyboard, having a common physical shape and electrical pin matrix, are adapted to specific peripheral devices by use of adapters that interface both with the generic bay and the specific peripheral device. Translation between USB protocol and standard serial protocol is accomplished by enhancements to a keyboard controller in the keyboard that also serves conventional keyboard functions. | |
