Is there a linux Driver module for Elitech data logger RC5 ?

[Bernard]

I HAD TO INITIATE A NEW ACCOUNT AT A NEW MAIL ADDRESS SINCE MY FORMER 
PROVIDER HAS UNEXPECTEDLY CLOSED UP. Sorry if you already got the 
following questions a few hours ago, any reply you may have sent won't 
reach me, please resend it to the list so it gets forwarded to me, or 
send it to my new private mail: bdebreil at free.fr

Thanks for your help.
I haven't yet succeeded in getting this device working.
There were two things to be tested.
The first one was proposed by Eero, who suggested a device setup by 'CIVIC'
     civic/elitech-datareader
This software implies that a serial driver get installed first. At this 
stage, I fail to undersand. A serial driver ??  Why on Earth ?  The RC5 
Elitech device is not 'serial', it is a usb device with a usb plug... To 
my knowledge, serial modules are somewhat outdated, and I don't know of 
any recent one, years have elapsed since every computer had RS232 serial 
ports... However, supposing that such system may operate with a device 
that is connected to a usb port, I ought to give it a try. 
Unfortunately, when the matter came to download the serial driver module 
for linux on a software site in China, I found that it was all written 
in Chinese, with barely 5 or 6 English words on each page, which was not 
enough for me to understand... I tested a few zip files which  I 
couldn't unzip, the zip module saying that it couldn't find needed parts 
of the files...

A comment was made by Robert :

'It might show up as a serial port (eg /dev/ttyACM? or /dev/ttyUSB?).  You
would then need to write a program that reads and decodes the messages 
sent.'

In my /dev directory, i found this :
     drwxr-xr-x  4 root       root          80 sept. 11 12:36 serial
     crw-rw----  1 root       dialout 188,   0 sept. 10 19:44 ttyUSB0

those 2 lines appear and disappear when plugging/unplugging the RC5, 
which confirms,
but I don't know what to do next.

Then Oliver did propose the second thing :

'first hit when googling "Elitech data logger RC5 linux" points to:

     https://pypi.org/project/elitech-datareader/'

the third line of the description:

     "Enables to use RC-4/RC-5 on Mac, Linux, Windows."

... kind of indicates it works'.

On this site, Brian R Mooga states that in 2015 he succeeded to get RC5 
Elitech data collector to operate on his linux system Ubuntu 14.04. His 
lsusb test said :

     Bus 002 Device 011 id 0c45:7401 Microdia

My system (Debian Stretch) says, when the device is connected to an usb 
port :

     lsusb
     Bus 001 Device 004 id 1a86:7523 Qin Heng Electronics HL-320 
USB-Serial adapter

I tested the url above
Below are the details :

I am on Debian Stretch, so I don't use 'sudo', but I log as superuser.

lsusb shows this :
     Bus 001 Device 004:ID 1a86:7523 QinHeng Electronics HL-340 
USB-Serial adapter

while Brian got in 2015 :
     Bus 002 Device 011:ID 0c45:7401 Microdia)


However I did install Python software as suggested. It went up to the 
point :

     .......................
     ......................
     # cd /home/bd/tmp
     # git clone git://....................................
     # cd temper-python/
     # python setup.py install

there, I got an error message, about the instruction ', encoding' that 
was said not to be available. I then edited the setup.py file and 
removed this parameter, and tried again :

     # python setup.py install

This time, I had no errors. But, if I launch :

     # temper-poll

it says :
     Found 0 devices

I tried the same thing on my laptop running ubuntu 14.04 and got the 
same results

Thanks in advance for more help
