-	 * the read (except when CRS SV is enabled and the read was for the
-	 * Vendor ID; in that case it synthesizes 0x0001 data).

+	 * Software Visibility enabled, reading the Vendor ID returns a
+	 * special data value if the device responded with RRS.  Read the
+	 * Vendor ID until we get non-RRS status.

+	 * If there's no Root Port or Configuration RRS Software Visibility
+	 * is not enabled, the device may still respond with RRS, but
