Hub not connecting to host
If you see that the PP15C is not connecting to the host system, one of the issues may be caused
by the USB drivers on your host system not being up to date. It is good practice to ensure you
have the latest drivers and updates installed on your host system, which is usually handled by
the OS, but sometimes may require an update directly from the USB host controllers
manufacturer, which will be found on their website.
USB drivers required are FTDI drivers, which can be found on the site

.
Daisy chaining multiple PDSync-C4 using expansion port
USB C cables can have variations in speed, power, and protocol capabilities. Some “active” or
E-mark type-C cables may not work on the daisy chain when connecting the expansion port to
another PDysnc-4. We recommend to use “passive” type-C cables and not to use cables fitted
with e-markers, see your cable supplier to see if e-markers are fitted.
Cannot access 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
applications that control the COM port before opening another.
7.6. No GUI
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.
