Solved Aeon Labs Z-wave Z-stick Gen5


I want to use Aeon Labs Z-wave stick in FreeBSD 10.2. It is supposed to be a usb serial device. On inserting the stick dmesg reports

ugen1.4: <vendor 0x0658> at usbus1
umodem0: <vendor 0x0658 product 0x0200, class 2/0, rev 2.00/0.00, addr 4> on usbus1
umodem0: data interface 1, has no CM over data, has no break

It seems that 'no CM over data' should not happen. Under Linux the device comes up as
usb 1-1: new full-speed USB device number 12 using xhci_hcd
usb 1-1: New USB device found, idVendor=0658, idProduct=0200
usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0
cdc_acm 1-1:1.0: ttyACM0: USB ACM device
usbcore: registered new interface driver cdc_acm

Is there any way to make this device usable?
I was able to get this going in a jail running openhab. The driver used was the umodem driver and fortunately, I did not have to add any VID/PID. To make this work, i specified the following.

Exposed usb devices to the jail via /etc/devfs.rules
add path 'cu*' unhide

Added openhab user to the dialer group.

Compiled openhab along with serial library following this:

In openhab.cfg, specified the device as zwave:port=/dev/cuaU0

Openhab reports the z-wave device correctly now.
