Solved : Unable to find my zwave device

[macpoupou]

After an upgrade of a debian VM, I had always the same error message: Driver: Failed to open the serial port: Error: Operation not permitted, cannot open /dev/ttyAMA0.
After a couple of months, I found only now why ! My usb device was blocked by usbguard.
Here are the following steps that I followed to fix the issue.

• Display the list of usb devices with lsusb

Bus 001 Device 003: ID 0658:0200 Sigma Designs, Inc. Aeotec Z-Stick Gen5 (ZW090) - UZB
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

• If your device is listed, unplug it and enter the following command: sudo dmesg -C.
  Plug it again, enter the following command: dmesg > usb.txt then more usb.txt

[ 2772.612186] usb 1-4: New USB device found, idVendor=0658, idProduct=0200, bcdDev
ice= 0.00
[ 2772.612194] usb 1-4: New USB device strings: Mfr=0, Product=0, SerialNumber=0
[ 2772.612477] usb 1-4: Device is not authorized for usage

• If your device is not authorized, enter: sudo usbguard list-devices --blocked.

• If your device is listed: sudo usbguard allow-device -p X where X is your device id (6 in this case)
• Then restart zwave-js-ui: sudo zwave-js-ui.restart
• Now another your device should be available with a new name (check /dev folder).
