Hi Orzor,
unfortunatelly I cannot help you.
PnP device is a term coming in 1990s- its meaning is, that the device can be configurable by software, so you dont need to setup anything with jumpers on the card (as it was usual in first PCs). As you can see, all devices sold now over world are PnP. The another meaning of PnP is, that the device is enumerable- can be 'discovered' by operating system.
All devices in the operating systems need driver. If the device behaves as a standardized one, the (standardized) driver is probably already in the operating system, so you plug and use (e.g. USB flash stick is a standardized device). For those devices, which dont behave as standard, producer can write a driver for operating system. A driver is a piece of code written specially to operating system. Note that USB itself does not cover the whole behavior of device, so there is not "USB device driver" in any OS covering all USB devices.
All this means that your drivers are (probably) for Windows(tm) OS. It is needed to write MQX driver.
