• if direwolf is saying you need to rebuild direwolf to support CM108 PTT, just install libudev-dev and rebuild direwolf again.
  sudo apt-get install libudev-dev
• https://github.com/wb2osz/direwolf/pull/168/files this will fix the problem ioctl HIDIOCGRAWINFO failed for /dev/hidraw0. errno = 0 keeps on appearing when after PTT is engaged.
• In the udev rules /etc/udev/rules.d/99-direwolf-cmedia.rules, make sure to change "0660" to "0666". 0666 means rewritabble by anyone.
