software no longer working after upgrade to Ubuntu 15.x

[sysmaster80]

After I upgraded the system to Ubuntu 15.x, the data collection from the device is no longer working. I think that it is not an issue with your software but with the usb link, however my knowledge of Linux is to limited to find the error. attached some clipping from Syslog, where I disconnected and reconnected the usb cable, and then restarted the cm160 program, and they are no longer talking to each other. (sorry no attachment, I can't upload a txt file, so... see below) Worked perfectly under 14.x.

I would appreciate if you could put me on the right track to fix it.

Best regards,

Luc

Hi, It looks like you don't have permission to configure the USB device (see last line of your log)

-> try to run the app as root (with sudo), it should work better.

To avoid this you should write a udev rule to change the permissions to your owl device. (https://www.google.be/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=udev+rules+usb+device+permissions)

Hi Philippe,

Thanks, for the swift reply, I'm getting closer.

And it has nothing to do with your software, more an issue within Ubuntu 15.x.

I syslogged a fresh boot and found that the cm160 is not started, initially I had also the impression that there was also a screw up on the usb/tty port, but that not confirmed yet.

(note: under 14.x it worked out of the box, and all files are still in the right locations)

Then I started cm160 as root in a terminal, and it was unable to communicate with the device, until I dis/reconnected it, now it is running flawless... probably until the next reboot.

So, I will be digging some more, you're of the hook (not that I ever expected an error on your side)

Some sideline information, I'm also Belgian, however do no longer master the French language, and live in Thailand. I modified your web pages so they match local conditions, and added a module that calculates my upcoming bill, based on the how they charge it here. KW rates change depending on the number of KW used within a period, whereby a period is one month but depending on district/area has a different cut-off date.

Thanks for your help,

Luc
