Troubleshooting Z-Wave Device Installation Issues

I’m reaching out to the community for some guidance on a problem I’m encountering with my Z-Wave setup. As a relatively new user to the Home Assistant ecosystem, I’ve been trying to transition from Wink, which unfortunately isn’t as reliable. I’ve successfully added my Z-Wave hub (HUSBZB-1), but I’m stuck when it comes to connecting any Z-Wave devices. I hit the ‘Add Node’ button under the Z-Wave management tab, and while it briefly turns green, nothing happens afterward. I’ve checked the OZW logs, and they show that the controller is queuing the add device command, but it doesn’t seem to progress beyond that. Here’s a snippet from the logs:

2019-12-04 13:26:24.776 Detail, Queuing (Controller) Add Device
2019-12-04 13:26:24.777 Info, Add Device
2019-12-04 13:26:24.777 Detail, contrlr, Queuing (Command) ControllerCommand_AddDevice: 0x01, 0x05, 0x00, 0x4a, 0xc1, 0x0a, 0x7b
2019-12-04 13:26:24.778 Detail, Notification: ControllerCommand - Starting

I’ve tried resetting the hub and ensuring all firmware is up to date, but the issue persists. Has anyone encountered a similar problem and managed to resolve it? Any advice or troubleshooting steps would be greatly appreciated. I’m really looking forward to getting my Z-Wave devices up and running to fully integrate my smart home setup. Thanks in advance for your help!
