+- current-speed : The current baud rate the device operates at. This should
+ only be present in case a driver has no chance to know
+ the baud rate of the slave device.

+ * device supports auto-baud
+ * the rate is setup by a bootloader and there is no
+ way to reset the device
+ * device baud rate is configured by its firmware but
+ there is no way to request the actual settings
