TC-08 CentOS 7 installation problem

Post by AUlibarrena » Thu Aug 10, 2017 10:48 am

I have a TC-08 data logger and I was told to use it to log temperatures. Before anything I installed the TC-08 drivers and the picoscope software from Then I connected the device to the computer and it is detected, as it shows when running lsusb:

Code: Select all

Bus 002 Device 005: ID 0ce9:1000 Pico Technology 
I then copied the 95-pico.rules (I've got it from this thread: topic3984.html) created a group called pico and added my user to it.
This is the output of getent group pico:

Code: Select all

So my user is in the pico group. After this, I run usbtest as my user and I've got:

Code: Select all

 - You are running this script as labuser.
 - You are in the following groups:
     labuser wheel wireshark

Code: Select all

Pico USB device found: /dev/bus/usb/002/005

 - It belongs to root (which is not you) who has permissions rw-
 - The members of group pico (which you are not in) have permissions rw-
 - Everyone else (this is you) has permissions r--
 - You CANNOT write to this device and so will NOT be able to use it.
   Please see the driver installation instructions for assistance in 
   resolving this problem 
When running it as sudo it detects the device and owns it but if I run picoscope later it tells me that there are no suitable devices connected (even as sudo). I know that I'm doing a number of mistakes so I would be very grateful if anybody could help me with this.

PicoScope is the application for our oscilloscopes, so when it reports "no suitable devices connected " it is correct.

There is currently no Linux version of PicoLog, the TC08 application, you would need to develop your own application using the API.
