Cannot connect Conbee 3 on QNAP

Hello,

I installed deCONZ docker image on my QNAP via Container Station.
Unfortunately I cannot see the Conbee 3 in the list of devices, it connects but does not appear in /dev.
On a Windows laptop it works, on a raspberry it works as well.

I tried to connect the Conbee 2 on the QNAP and it shows as expected on the same usb port where the Conbee 3 was attached.

Below log output first the Conbee 2 and than the Conbee 3:

dmesg

[SOLVED]
Affter few trials loading the below module allows the device to be loaded. still need to test if it actually works.

# insmod /lib/modules/others/ftdi_sio.ko

[41503.420666] usb 1-3: new full-speed USB device number 32 using xhci_hcd
[41503.565190] ftdi_sio 1-3:1.0: FTDI USB Serial Device converter detected

I used the below script to automatically load at startup the module on the QNAP based on this guide:

cat /tmp/config/autorun.sh
#!/bin/sh
/sbin/insmod /lib/modules/others/ftdi_sio.ko
if lsmod | grep ftdi_sio > /dev/null; then
    echo `date` "[ OK ] autorun.sh: ftdi_sio.ko module loaded" >> /var/log/autorun_script.log
else
    echo `date` "[FAIL] autorun.sh: failed to load ftdi_sio.ko module" >> /var/log/autorun_script.log
fi
