Hi to Everyone,
I’ve been using this temperature recorder for a number of years. To get it
to work on Debian, I had to install a program with Python, according to a
doc I had found. This generated a directory named elitech-datareader-1.0.5,
which provides commands to program the recorder as well to recuperate
recorded data. I still have this on my Debian 11 system, and it still works.
Problem is : over time, the recorder became wet inside, so I decided to buy
a new one of the same model. The new one I received is exactly the same
RC-5… but it appears that the software has changed : it no longer works on
my system. The elitech site only proposes software for Windows and Mac…, but
it said the same thing in the old days (maybe 2017) at the time I had found
what still works on my old RC-5.
The old RC-5 is an USB device. Whenever plugged into a usb port :
$ lsusb
Bus 001 Device 088: ID 1a86:7523 QinHeng Electronics CH340 serial
converter
If I replace the old RC-5 by the new one, the above line disappears for the
lsusb output, but another line appears instead :
Bus 001 Device 089: ID 246c:9001 FMSH MSC+HID
[...]
You might want to do "sudo dmesg | tail" shortly after inserting the device
(say a couple of seconds or five). Perhaps that allows us to see what the
kernel is making of this. Poking around in the Intratubes suggests that this
is a "combined USB device" offering a storage and a HID (that's the MSC+HID)
interface.
Cheers
