The ONavi USB sensors (both the 12-bit and 16-bit) are now fully working under Linux with both QCNLive and QCN under BOINC. No drivers are needed to install. As the ONavi sensor shows up as a "pseudo-modem" (/dev/ttyACM0) you may need to check the permissions to ensure that your account has read/write permissions to this device. For example, you may have to add your account or the BOINC account to the "dialout" group so it has permissions to use the ONavi sensor. The other QCN USB sensors (JoyWarrior and MotionNode) already have Linux support.
