darwin: work around devices with buggy endpoint descriptors

This commit adds a workaround for devices that have buggy endpoint
descriptors but are otherwise functional. These devices will have
endpoints that fail the GetPipeProperties call. Since we only care
about the endpoint address we can read it from the descriptor
itself.
