Stopping Cablecast Device Control
Before beginning the upgrade we will disable Cablecast Device Control to prevent Cablecast from attempting any serial communications during the upgrade. Its also important to turn off any other software that might be performing serial communications. To disable Cablecast Device Control:
Right Click on My Computer
Select Manage
Select the Services panel on the left
Find and select CablecastDeviceControl in the list of services.
Click Stop with the Cablecast Device Control service selected to disable the service.
Uninstalling Existing Drivers
Next, we will uninstall the current drivers:
Right-click My Computer
Select Manage
Navigate to Device Manager
Expand the Multi-port serial adapters node
Right-click ESU2-400 Eight RS-232/422/485 Serial Ports
Select Uninstall
Check Delete the driver software for this device in the confirmation window that appears
Click OK to uninstall the Quatech drivers.
Once the drivers are uninstalled, right-click the computer name at the top of the device list and choose Scan for hardware changes. This will rediscover the Quatech device without the drivers installed. The scan can take a minute or two to complete. A warning that the system was unable to install the device correctly may pop up when you rescan. It is safe to ignore the message unless it comes up after the new driver has been installed.

Locate and double-click the firmware updater in the folder that the USB2.0 firmware zip folder was extracted to in step 8 of the Downloading Latest Drivers and Firmware section above. (For the current version as of this writing, it is called USBU_434.exe)

Check your Cablecast configuration to confirm that the device and router port assignments are still configured correctly. Contact support@cablecast.tv if you need assistance reconfiguring Cablecast.
