+# Purpose  : udev rules for the Yaesu FTX-1 via USB-C
+#
+# Preconditions:
+# 1. Yaesu FTX-1 is selected via et-radio
+# 2. Yaesu FTX-1 is connected via USB-C cable
+#
+# Postconditions:
+# 1. /dev/et-cat created
+# 2. /dev/et-audio created
+# 3. rigctld is started
+# 
+# Note: As of 05/21/25 Yaesu has not published their CAT control command specification. This is a
+#       temporary integration that does not include CAT control support. It will only key the PTT
+#       and provide audio in/out. You MUST set the frequency and mode yourself.
+
+# Special rule to ensure that the second serial interface (/dev/ttyUSB5) is tagged as ET_DEVICE=FTX-1 so
+# that it can be used in the next CAT control rule.
