Unknown devices
Sometimes, within Liveviewer and device manager, the connected device may show up as an
unknown device.
This can be due to the host system needing to be trusted on the device. This can be done on
the device itself on the initial connection.
This could also be due to an insufficient number of endpoints available on the USB controller in
the host system. This limitation within the USB controller can only be resolved if you connect
fewer USB devices to the controller in question.
Cannot connect any more devices
Sometimes, you may reach the endpoint limit of your USB controller and this may stop you
from being able to attach any more devices to your host system.
You can create more space is to change connections from USB3 to USB2. You can change the
connection by disabling USB3 in the BIOS on startup.
A much simpler way is to use USB2 cables instead of USB3 cables, limiting the connection to
USB2.
7.5. Hub connection issues
If you have issues with the hub and connecting to your host system, please see below
troubleshooting solutions.
Hub not connecting to host
If you see that the OEM PDS-C4 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
