You can probably do better for a fallback. For example, you can format the vendor ID and product ID into a string. For an extreme take on this, see the Copy_DeviceName() function in Apple's HID Calibrator sample code: https://developer.apple.com/library/mac/samplecode/HID_Calibrator/Listings/H...
Oh, and for the case where device is NULL, it's fine to return NULL. It should never happen and, if it does, we want a crash to figure out why and fix things in a better manner, rather than papering over it with a bogus value.
