Here are a couple things to check:

• If you plug the Tangara into your computer and turn it on, then (in a terminal) run
  
  Code:

  dmesg | tail -n 20
  you should see messages about it recognizing the Tangara - a bunch of timestamps and usb-related messages, and "Product: Tangara" in there somewhere.
  

•  In the same output, you should see something like "ttyACM1" that tells you the device it's using.  If you then run
  
  Code:

  ls -l /dev/ttyACM1
  (or whatever the ACM number was) you should see some permissions and then the owning user and group, something like "root dialout".  If you then run
  
  Code:

  groups
  you should see "dialout" listed (or whatever the group was).  If you don't, you need to add your user to that group using something like
  
  Code:

  sudo usermod -aG dialout $USER
  and then logout/login or reboot.
  

Thank you! That did the trick and my device is now updated!
