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)
Which setupapi
functions are needed for this hack?
Right now its a hardcoded hack to
SetupDiGetClassDevsA that looks for the
iPods Vendor ID by talking to the /proc filesystem. I was hoping we could make it generic enough that
ReactOS and Wine could
both use the same code for device identification at least on the userspace
side because if I understand it correctly all USB devices under any OS use
the same ID system. I dont know how the other hardware such as PCI and
friends work.
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
