I am running Home Assistant as a docker installation on my QNAP TS-251+ NAS and wanted to add Z-Wave/ZigBee capabilities to my home automation using the HUSBZB-1 USB Stick, a combined Z-Wave/ZigBee controller. Got mine for ~45EUR incl. shipping and import tax from amazon.com.
Stick arrived today – plugged into the NAS – checked if detected as USB-Serial – NOPE 
A quick “lsusb” dump told me that the device has been detected, but the drivers where not loaded, so no /dev/ttyUSBx – QNAP is not loading the modules by default.
FIX:
Login to your QNAP via SSH an run the following commands:
Re-plug the stick and you (should) have two new devices: /dev/ttyUSB0 and /dev/ttyUSB1 
And if you want to use a Aeotec AEOEZW090-C Z-Wave controller, log in to your QNAP and run
Conbee:
insmod /usr/local/modules/ftdi_sio.ko
