 # Used by dectalkDriver, litetalkDriver, doubletalkDriver, and tripletalkDriver.
 # USB serial devices are supported if Linux exposes them as /dev/ttyACM*
 # or /dev/ttyUSB*. USB-only synths with no tty device need a separate driver.
-# auto checks /dev/ttyACM* first, then /dev/ttyUSB*.
+# Set an explicit device for stable hardware speech. auto only uses devices
+# that respond to a driver-specific probe and may fail on silent synths.
 # Examples:
 # hardware_device=/dev/ttyACM0  # RPITalk USB gadget mode
 # hardware_device=/dev/ttyUSB0  # USB serial adapter
 # hardware_device=/dev/ttyS0    # built-in serial port
