USB Stick / VendorID und ProductID

[Robert Marquardt]

Und schon ist die Antwort da. Von Walter Oney dem Treiberexperten.
Leider ist die Antwort negativ. Es geht nicht.

Zitat:

Using what kind of system call? There is no single driver that's
guaranteed to be in every device stack above the function driver and
responding to IOCTL requests. I don't think there's any way to convert
an arbitrary file handle into a SetupDiXxx info handle in order to query
the device properties. I think you are basically SOL here, which makes
sense because there's nothing about a handle that ties it to the USB
bus.
