Permissions reset in /dev/ttyUSB0

I am trying to get my arduino to work with the IDE. In order to do this, I added my account to the uucp group, and it sort of worked. But the permissions keep reseting to 0188 on /dev/ttyUSB0, which prevents me from using it.

I also tried adding 'KERNEL=="ttyUSB[0-9]*",NAME="tts/USB%n",SYMLINK+="%k",GROUP="uucp",MODE="0666"' as a rule, per this site's advice, https://openbci.com/forum/index.php?p=/discussion/597/fixing-linux-write-permission-for-dev-ttyusb0, with no results.

I've never seen an 8 in UNIX permission modes. Are you sure this is what you see?
