+# Author   : Gaston Gonzalez
+# Date     : 30 September 2024
+# Purpose  : udev rules for the DigiRig Mobile v1.9 
+#
+# Preconditions:
+# 1. DigiRig Mobile  connected via USB cable
+# 2. This rule is processed after the IC-7200
+#
+# Postconditions:
+# 1. /dev/et-cat created
+# 
+
+# The IC-7200 uses the same chipsset. In order to avoid incorrect detection, we will check
+# for the presence of ET_DEVICE as the IC-7200 will set it as an earlier rule. With this
+# approach, the DigiRig Mobile rules must be processed later in the chain.
