All versions of windows have a driver called SERENUM that will read the PnP
id from an attached device using an obscure protocol.

Most drivers support an interface that uses CreateFile, ReadFile, WriteFile,
and/or DeviceIoControl. You can apply either of these general strategies to
learn what you need to know:

Plan A: By means of a prodigious feat of mentation, possibly involving
telepathic contact with the author of the driver, deduce the correct
interface.

Plan B: Obtain documentation from the hardware vendor about how to use their
driver.

I'd go with plan A, but first I would need either a cell from their body (either from a hair follicle or a sample of their blood) to use for my witchcraft.

iago, you're really out of date. Should go get Teach Yourself Telepathy in 21 Days from your local book store.
