Hi all,
I wanted to have the TC-08 that works nicely under Windows log data with a laptop running Ubuntu Linux.
Versions: Ubuntu 22.04 (tried also 20.04.6)
PicoLog 6.2.7 (cannot find older version to try).
After setting usb permissions in /etc/udev/rules.d I can start the AppImage, but it will not detect the device.
"lsusb" shows the Pico device with a correct VendorID (0ce9).
(created a file 95-pico.rules with 1 row: ATTRS{idVendor}=="0ce9", MODE="777")
I can start the AppImage with a double click. It seems to work but will never see the TC-08.
If I start it from terminal I do get some error messages:
./picolog-6.2.7-x86_64.AppImage
[3998:0408/180006.215804:ERROR:sandbox_linux.cc(377)] InitializeSandbox() called with multiple threads in process gpu-process.
(node:4019) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.
(Use `exe --trace-deprecation ...` to show where the warning was created)
If i try to start is as root I cannot - even more errors and only a white box loads with no graphics!? probably some AppImage thing...
I also tried to manually install the TC-08 drivers - no change.
(sudo apt-get install libusbtc08-1 )
Any help deeply appreciated!
Cheers!
PicoLog under Linux does not see a TC-08
Re: PicoLog under Linux does not see a TC-08
Same issue here.
Running a fresh installation of Ubuntu 22.04LTS. Dowloaded latest PicoLog 6.2.8 from https://www.picotech.com/downloads and followed the installation notes.
I also tried to install PicoScope 7 Stable from https://www.picotech.com/downloads/linux. This worked, but still unable to PicoLog.
Then I tried to install the packages libusbtc08 and libpswrappers (just for testing), but theses are not available for Ubuntu 22.04.
I have the same issue on my Raspberry Pi 4 where I installed the according .deb package.

Re: PicoLog under Linux does not see a TC-08
Btw, when I run the AppImage from command line, I can see that the software recognices the TC-08 somehow from the log messages when I connect/disconnect the device, but it will not show up in the GUI somehow.

Re: PicoLog under Linux does not see a TC-08
Can you try
and see if that helps.
There is a known issue in this area which we are looking into, it affects a number of applications built using Electron, including PicoLog 6
