Application Does not See USB Device cp210x

Post by kerner1000 » Sat Dec 28, 2019 12:40 pm

the application "BL-30/Datalogger.exe" needs to connect to usb, but it seems it does not see the attached device.

tail /var/log/syslog:

The device that should connect is /dev/ttyUSB0.

I assume the USB configuration is correct like this, but the application "BL-30/Datalogger.exe" does not show any USB device.

What else I could do to see whats wrong?

Many thanks!

Resolved this issue by setting the baud rate:

Code: Select all

sudo stty -F /dev/ttyUSB0 speed 38400

Also, the current user needs to be member of the "dialout" group:

Code: Select all

sudo usermod -a -G dialout alex
