The issue hits you when you are installing from source and starting from scratch. Also apparently the driver/firmware needs to be compiled for the kernel version you are using too. So any time the operating system changes you are left with a driver that won't work. Having recently finished installing Domoticz on my Synology (Debian Chrooted), and it was the HGI80 drivers that caused me the most grief. Luckily there is a guy that compiles these for Synology.
