I've heard about the PnP support in the newest Linux versions. Their HAL
sounds a lot like our PnP Service. Maybe the Wine people should rather have
a look at that - I doubt direct access can be made portable enough (save
for some special cases - e.g. SCSI)

it depends (but in general it's some variation of the vendor id/device id
scheme). In fact, Windows has several enumerators, one per bus, each
supporting a different kind of device enumeration and identifications (FYI,
PCI devices have a vendor id, a device id, a subsystem vendor id, a
subsystem device id and a revision id), plus a root enumerator that
implements a default behavior (the identifier is a GUID) that should be
good enough for everything else (if not, you write your own enumerator).
You generally don't use these identifiers directly, anyway
