1418 | * Enumerate the USB devices in the host system. Since we do not care about the hierarchical

1419 | * structure of root hubs, other hubs, and devices, we just ask the USB PnP enumerator to
|
---|
1420 | * give us all it has. This includes hubs (though not root hubs), as well as multiple child
|
---|
1421 | * interfaces of multi-interface USB devices, which we filter out. It also includes USB
|
---|
1422 | * devices with no driver, which is notably something we cannot get by enumerating via
|
---|
1423 | * GUID_DEVINTERFACE_USB_DEVICE.
|
---|
1424 | *
|
---|
1425 | * This approach also saves us some trouble relative to enumerating devices via hub IOCTLs and
|
---|
1426 | * then hunting through the PnP manager to find them. Instead, we look up the device's parent
|
---|
1427 | * which (for devices we're interested in) is always a hub, and that allows us to obtain
|
---|
1428 | * USB-specific data (descriptors, speeds, etc.) when combined with the devices PnP "address"
|
---|
1429 | * (USB port on parent hub).
|
---|
1430 | *
|
---|
1431 | * NB: Every USB device known to the Windows PnP Manager will have a device instance ID. Typically
|
---|
1432 | * it also has a DriverKey but only if it has a driver installed. Hence we ignore the DriverKey, at
|
---|
1433 | * least prior to capturing (once VBoxUSB.sys is installed, a DriverKey must by definition be
|
---|
1434 | * present). Also note that the device instance ID changes for captured devices since we change
|
---|
1435 | * their USB VID/PID, though it is unique at any given point.
|
---|
1436 | *
|
---|
1437 | * The location information should be a reliable way of identifying a device and does not change
|
---|
1438 | * with driver installs, capturing, etc. USB device location information is only available on
|
---|
1439 | * Windows Vista and later; earlier Windows version had no reliable way of cross-referencing the
|
---|
1440 | * USB IOCTL and PnP Manager data.
