Under Linux no driver is required. The hardware can be accessed directly using the libusb-1.0 library. But permissions have to be managed.
To grant access to all users of the group usb, add the following UDEV rules e.g. to /etc/udev/rules.d/99-ztex.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="221a", ATTR{idProduct}=="0100", ACTION=="add", MODE="0664", GROUP="usb"
SUBSYSTEM=="usb", ATTR{idVendor}=="04B4", ATTR{idProduct}=="8613", ACTION=="add", MODE="0664", GROUP="usb"
SUBSYSTEM=="usb", ATTR{idVendor}=="04B4", ATTR{idProduct}=="1480", ACTION=="add", MODE="0664", GROUP="usb"
