Frequently Asked Questions

Q: Does the USB Hub Macro Controller require any driver installation to work?

A: No driver installation is needed. The device uses the WebHID API, so all configuration is done directly in a compatible browser (such as Google Chrome or Microsoft Edge). Simply plug in the controller and open the configuration web page to start customizing your keys, encoder, and lighting modes instantly.

Q: Will my custom key assignments be lost if I unplug the macro controller?

A: No. All configurations — including programmable key bindings, encoder settings, and lighting preferences — are saved to the device's built-in non-volatile memory. Your settings persist through power loss and are restored automatically every time you reconnect the device.

Q: Can I use multiple USB Hub Macro Controllers on the same computer at the same time?

A: Yes. Each unit is assigned a unique 6-digit device ID at the factory, so the system and the WebHID configuration interface can distinguish between multiple connected controllers without conflicts. This makes it easy to set up dedicated macro pads for different applications simultaneously.

Q: What kinds of commands can I assign to the programmable buttons?

A: Each of the 3 programmable keys supports up to 3 sets of key values per key. Supported input types include modifier keys (Ctrl, Shift, Alt, Win), standard keyboard keys, and multimedia control commands (play/pause, next track, volume up/down, etc.). The rotary encoder press button can also be independently assigned its own command.
