Location of Public USB Ports
Unlike the CommBox Classic, where public USB ports are clearly labelled on the front, the CommBox Pulse features a more streamlined design.
-
The public USB ports are located on the left-hand side of the screen (when facing the display)
-
These ports are unlabelled for aesthetic reasons but function the same as on the Classic
💡 Tip: These USB ports are easy to access for classroom or meeting room users needing to plug in a USB drive quickly.
How the Ports Work
-
These USB ports pass through to the Android operating system
-
They also connect to an external Windows PC or OPS (Open Pluggable Specification) unit if installed
-
Plug in USB drives, keyboards, webcams, or other compatible devices
💡 Tip: For the best experience, make sure your device is formatted correctly (e.g. FAT32 or exFAT) if you’re using USB storage.
Troubleshooting / What to Do If It Doesn’t Work
-
Ensure the USB device is securely plugged in
-
Try the same device in another USB port to confirm it's not faulty
-
Check the input source – the USB may only show under Android or the connected PC depending on your current mode
