Frequently Asked Questions - UCS 303 Extron
What is the data transfer speed of the Extron UCS 303 USB hub?
The UCS 303 supports USB 3.0 with speeds up to 5 Gbps. It is fully backward compatible with USB 2.0 (480 Mbps) and USB 1.1 (12 Mbps) devices.
How many devices can I connect to the UCS 303?
The hub has 3 downstream USB 3.0 Type-A ports, allowing you to connect up to three USB devices simultaneously.
Does the UCS 303 require an external power supply?
Yes, for optimal performance with high-power devices (e.g., external hard drives), use the included external power adapter (5V DC, 2A). It can also run bus-powered for low-power devices like keyboards and mice.
Is the UCS 303 compatible with USB-C devices?
The hub uses USB 3.0 Type-B upstream and Type-A downstream. To connect a USB-C device, you will need an appropriate adapter or cable (e.g., USB-C to USB-A).
What operating systems are supported?
The UCS 303 works with Windows, macOS, and Linux. No additional drivers are required for basic functionality.
Can I daisy-chain multiple USB hubs?
While technically possible, daisy-chaining can reduce performance. For best results, connect each hub directly to a separate USB port on your computer or use a powered hub.
How do I know if the hub is powered on?
When connected and powered, the blue power LED on the hub will illuminate. Each active port also has a green activity LED that blinks during data transfer.
What should I do if a connected device is not recognized?
First, check the device driver. Then try connecting the device directly to the computer to rule out hub issues. Ensure the hub is powered if using high-power devices. Restart your computer if needed.
Can I mount the UCS 303 under my desk?
Yes, the hub is designed for desktop use but supports optional under-desk mounting via a separate bracket (available from Extron).
What is the warranty for the Extron UCS 303?
Extron provides a 3-year limited warranty on the UCS 303. Refer to the product documentation for details.
