The Zstick has been recognized by Domoticz !!! :shock:
Thank you so much :D

So I installed your latest package, but I had to do the mknod myself.
Not sure if domoticz is started with the root privileges.
Where is the start script?
I did a "grep -r mknod *" in /usr/local/domoticz but I found ...

I checked now and cdc-acm was missing in domoticz_88f6281-4.2_2.0.3798-7.spk.
The compile of a new version is on the way :-)
You can also download compiled cdc-acm for 88f6281 for DSM 4.2 here: http://jadahl.dscloud.me/cdc-acm.ko
Copy it into /lib/modules and do a insmod

I ...

In newer DSM the cdc-acm.ko is in the kernel.
I thought I had compiled cdc-acm.ko in domoticz_88f6281-4.2_2.0.3798-7.spk package?
Which version do you have installed now?
Regards
Jumbotroll

The installed version is domoticz_88f6281-4.2_2.0.3798-7.spk
Maybe an unseen compilation error, or a ...

Do you have /usr/local/domoticz/modules/cdc-acm.ko ?
Then you can try insmod /usr/local/domoticz/modules/cdc-acm.ko

If that not work you can try to copy cdc-acm.ko to /lib/modules/

I do not have it:
DiskStation> ls /usr/local/domoticz/modules/
ch341.ko cp210x.ko pl2303.ko ...

I think you are missing cdc_acm.
Try this: insmod /lib/modules/cdc-acm.ko

Indeed...
DiskStation> insmod /lib/modules/cdc_acm.ko

The old package from synocommunity does not support OpenZWave.
Can you check if you have this modules:
/lib/modules/usbserial.ko and
/lib/modules/ftdi_sio.ko

If you run lsmod
The last line should show something like this:
usbcore 176292 17 ch341,snd_usb_hiface,snd_usb_audio,snd_usbmidi_lib,cdc ...

Sorry, but I have No idea why this is not working on your NAS.
Can you check if you have: /usr/local/domoticz/rules.d
60-synocommunity.domoticz.rules

#rules for USB ACM serial devices
KERNEL=="ttyACM*", ACTION=="add", MODE="0666"
KERNEL=="ttyUSB*", ACTION=="add", MODE="0666"

I also uninstalled any other (non-related) packages on my Synology (sabnzbd, sab2, perl, python).
Reinstalled domoticz as above, but still the same result.
The Stick is seen by the DSM, but not by Domoticz

I did the same without the stick plugged.
Uninstall package
reboot
install the new package (domoticz_88f6281-4.2_2.0.3798-7.spk)
reboot
start domoticz
Plug the zstick

Still no /dev/ttyAMC device in the "serial port" list.
Only /dev/ttyUSB0 to /dev/ttyUSB7. None of them is working.

Something ...

There may be conflict if you use both UsbSerialDrivers and domoticz package with drivers .
Delete both packages and restart NAS .
Then install only this package including cdc-acm driver :domoticz_88f6281-4.2_2.0.3798-7.spk http://jadahl.dscloud.me/sspks/packages/domoticz_88f6281-4.2_2.0.3798-7.spk ...

I'm out of ideas why this does not work on your NAS .
Do you use USB Hub ?
If so, test without USB Hub .
Regards
Jumbotroll

I do not use USB hub.
There is only a brand new 10m USB cable between the NAS and the key.
I tried without it at the beginning, but my last attempts were made with it ...

Thanks again :)
I uninstalled the older one and installed this one.
I didn't know if I should keep the serial drivers, so I kept them.
It was still not recognized.
I uninstalled the serial drivers with no more success.
Here is the output of dmesg when plugging in the stick (without serial drivers ...

Yeah !
Windows 8 and 10 does not need any additional driver.
But Windows 7 does.

So I installed this driver , and I could finally install the stick on Windows.
Domoticz can now see it !
Thanks :)

Well, it is not such a good news, it means I miss something on my Synology...

Even if I do not have ...

I installed Domoticz on a recent Windows 7.
Then ran domoticz.
Then plugged the stick.
The Aeotec GEN5 USB stick is still not recognized.

I can see this window for long:
https://dl.dropbox.com/s/jg4mzoxt9y1xduk/gen5_driver_win.jpg?dl=0
and finnaly I had the message 'no driver found".

Before to ...

Well, I tried the 4.2 package you compiled, without and with the USB serial drivers.
For both, I rebooted the NAS after installation, before to plug the USB stick.

I still have the same error message, and nothing is added to dmesg.

I will install a Windows version of domoticz on my laptop tomorrow ...

I have compiled a 4.2 package you can test if you want.
I don't think it does matter if it is for 4.2 or 4.3, but as a last try you can test if you want.

Thanks again :)
I will test it ...

Yes you can select all drivers.
Did you try to reboot your Synology before you installed new package?
I have never had any problem remove the old package with SSH, but I have a different synology with x86 cpu.
With SSH:
From the command line you can just remove the directory 'rm -rf /var/packages ...

Failed even when domoticz was stopped.
I logged with ssh and removed the directory /volume1/@appstore/Usbserialdrivers

Now the installation of 3.0.6 tells me that it could not install it because it is already present.
I indeed see a package which status is "error", but I still cannot uninstall it ...

Indeed, I have DSM4.2-3255.
Installation of 3.0.5 went wrong, but it seems that something has been installed.
The installation of the 3.0.6 needs the desinstallation of the 3.0.5.
But I cannot uninstall 3.0.5 ! :( Just a pop-up window saying it could not uninstall.
The system log has only a single ...
