Cannot access the COM port
You may get an error message stating "COM (and then a number) could not be opened (Access is
denied)".
This is because an application has control over the COM port that the hub is connected to, and no
subsequent application can access the hub. To resolve this, you will need to close any other
applications that are using the COM
port before trying to use the COM port.
7.6. Using with a headless system
If you are using a headless system with no GUI, then and you require to enable logging for support
issues, you can use the following command to create the logging cfg file manually:
echo
*=debug>/etc/opt/cambrionix/cambrionix.log.cfg
Then after re-producing the problem, you can zip the logs from the folder
/var/log/cambrionix
You may delete the file below when you are finished with it.
/etc/opt/cambrionix/cambrionix.log.cfg
7.7. Software troubleshooting
Some users have noted that the API can cause a high level of CPU usage. This can sometimes be
linked to the API recorder service. If you are finding this and you are not using it then we would
recommend to uninstall it from your system entirely. Information on how to uninstall programs can
be found in the
Removing Software section.
Firmware Update
If you have older hardware with Firmware version number lower than 1.83 then the hub may not be
compatible with the Cambrionix API and will need to be updated to the latest version of Firmware
using the Command Line Updater which can be downloaded and installed from the following link.
