I had the same problem. You have to put the following line in the file etc/udev/rules.d/49-teensy.rules

# 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)
#   or
# /lib/udev/rules.d/49-teensy.rules    (req'd on some broken systems)
#
# To install, type this command in a terminal:
#   sudo cp 49-teensy.rules /etc/udev/rules.d/49-teensy.rules
#
# After this file is installed, physically unplug and reconnect Teensy.
#
ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789]?", ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789]?", ENV{MTP_NO_PROBE}="1"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789]?", MODE:="0666"
KERNEL=="ttyACM*", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789]?", MODE:="0666"
#
# 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
#   SUBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789]?", GOTO="nm_modem_probe_end" 
#

You can get this file from : https://www.pjrc.com/teensy/49-teensy.rules

Under Windows and Linux, you may wait the COM port to be available. Try to upload the program again after few seconds.

Reset button may be used under emergency case only.
