Im developing an aplicaction to control an scanner via USB and im following the steps to comunicate with a hid (human device interface), at first im trying to get the GUID of my device, but somethig strange happens, i always get the GUID
4D1E55B2-F16F-11CF-88 CB 00 11 11 00 00 30 for my device, no matter if a dont have any devices atached or many devices atached, so i try to find that GUID on the REGEDIT, but there is not such a GUID on my registry, i tried on other computers but the result was the same, but in other PC`s i foud that GUID, but it seems to belong to a mouse, so i wuld like to to know why, i am reciving the SAME GUID all the time?
to do this im using SetupDiGetDeviceInterfaceDetail function.
by the way �Why the SO generates the same GUIDs, if it has 128bit combination to do this?
