Actually, almost anything you need is in DDK. Device Driver Kit from microsoft. It used to be free for download. Now it is free for MSDN sub scriber. If you had it. Its help file will be everything you want to know.

In the case of a hot plugged device like a USB thingy, USB has four connections, two power supply lines and two differential signal lines. One signal line is pulled up with a resistor, pulling up one line indicates a low speed device, the other, a high speed device. The line being pulled up signals the OS that a device has been attached, the OS then goes through a process of enumeration, requesting device descriptors from the device that describe it's functions. The OS then searches it's database of drivers and loads the appropriate one.

Hi,

there is a Plug'n Play protocol for almost all peripherals in the PC, starting with PCI, and USB (these are native PnP) and going on with the serial port, parallel port and ISA. If you search around the net you'll find these protocols, or drop a message and I'll send them to you. As far as I know the IDE interface has no PnP or other kind of hot plug protocol for finding devices.
