    Nortek HUSBZB-1 - Ubuntu - CP210x driver - Working

    Hey guys,

    Finally had time to test the Nortek HUSBZB-1 dongle using the HS4 beta Zigbee plugin. Ubuntu was able to see the serial port.

    dmesg | grep tty

    [ 0.137272] printk: console [tty0] enabled
    [ 5.423656] usb 1-1: cp210x converter now attached to ttyUSB0
    [ 5.426066] usb 1-1: cp210x converter now attached to ttyUSB1
    [ 5.426630] usb 1-2: pl2303 converter now attached to ttyUSB2
    [ 5.427266] usb 1-3: pl2303 converter now attached to ttyUSB3

    However the plugin was not able to access it. After some research, I found the Nortek uses the CP210x driver. Ubuntu 20.04.1 LTS has the driver built into the kernel. Out of curiosity, looked at how to build the driver in Linux. On the Silabs site, found this document. .

    Sometimes a serial device needs its permission altered, so tried that. It turns out, I needed to chmod the ttyUSB0 and ttyUSB1 device. Then the Zigbee plugin was able to see and use the Nortek device.

    sudo chmod 666 /dev/ttyUSB0
    sudo chmod 666 /dev/ttyUSB1

    The ran the wizard to add the device with the beta HS4 Zigbee plugin. Choose ttyUSB1, and it seems to be working. Now to find devices....

    Take care,

    I have validated that the cp210x driver is installed and it does recognized the Nortek stick when inserted, but there are no ttyUSB devices created. Did I miss a step? Thanks!
