fixed/win32: HID devices were displayed twice in the peripherals wind…

…ow. fixed by scanning for RAW guid only. devices will be displayed with type 'unknown', but since the same device has a different guid when scanning the HID guid than when it's found by scanning the RAW guid and none of the other values except vendor id and product id match, this seems to be the only solution
