No USB device (Datalogger DL2.0USB on meteohub, iConnect)

[zeppo]

Hallo community,

Im new in the forum an need your help, please:

I've aquired a new "meteohub on iConnect" solution for online presentation the weather data of my Davis Vantage Pro 2 (WDLive).
iConnect could be the perfect solution for me (small form factor, WLAN, low price, low power consumption).

The system ist running stable with version 4.8h, the webserver access works fine.

And now my problem: I use the DL2.0 USB Datalogger (Fjord Technology). The DL is recognized on the USB port of meteohub (checked with dmesg), but no USB device is available in /dev (I would expect something
like this: /dev/ttyUSBx or /dev/ttyMHxy ...).

dmesg:

--> The VantagePro2 has no connection to meteohub.


On my Windows7 PC, together with WsWin, the Datalogger works! Its function seems to be OK in principle.

Who can give me help to make the the DL2.0 working with meteohub?

Thanks

Fjord has the habbit to use standard usb-serial chips but gives them unique USB product IDs.
As a result, the standard drivers delivered by the usb-serial chip manufacturers, which are
part of standard Linux distributions cannot recognize these. On your Windows systems Fjord
may provide adapted drivers, but Meteohub's Linux can't know about these.

I put a forcing rule to load the ftdi driver for the Fjord xpb adapter to the Meteohub
distro and will add one for the Fjord USB adapter with the next update. Hopefully, they
will not invent more IDs in the future

To fix your problem right now - not wating for the next update - you can unzip the attached file
and place it into "/etc/udev/rules.d/" manually.

Thank you for fast reply!

I've insert the new rule followed by restart udevd, but no changes. No "/dev/ttyUSBx" or similar device.
Is there a difference in Fjords "DL2.0USB" or "XPB"- Data loggers according the USB drivers? (I use the DL2.0USB).

Chiao

The xpb has a different product id. There should be both rules (z70 for xpb and z71 for usb) is your udev rules directory. Are they?

[zeppo]

@ admin:

Yes, ther'e both rules z70 and z71 with different productId (original from your zip file). But no detection of "/dev/ttyUSBx" after restart of udev hotplug service (/etc/init.d/udev restart).

does a reboot help?

[zeppo]

I'm so excited!
The reboot helped. It works now. My Davis Vantage Pro2 is connected with meteohub on iConnect!

Thank you very much!
