+# UDEV Rules for Teensy boards, http://www.pjrc.com/teensy/
+#
+# The latest version of this file may be found at:
+#   http://www.pjrc.com/teensy/49-teensy.rules
+#
+# This file must be placed at:

+# /etc/udev/rules.d/49-teensy.rules    (preferred location)

+#
+# To install, type this command in a terminal:
+#   sudo cp 49-teensy.rules /etc/udev/rules.d/49-teensy.rules
+#

+# If you share your linux system with other users, or just don't like the
+# idea of write permission for everybody, you can replace MODE:="0666" with
+# OWNER:="yourusername" to create the device owned by you, or with
+# GROUP:="somegroupname" and mange access using standard unix groups.
+#
+#
+# If using USB Serial you get a new device each time (Ubuntu 9.10)
+# eg: /dev/ttyACM0, ttyACM1, ttyACM2, ttyACM3, ttyACM4, etc
+#    apt-get remove --purge modemmanager     (reboot may be necessary)
+#
+# Older modem proding (eg, Ubuntu 9.04) caused very slow serial device detection.
+# To fix, add this near top of /lib/udev/rules.d/77-nm-probe-modem-capabilities.rules
