Description
The DigiFusion U3H390S is a high-performance connectivity bridge engineered for users who demand both speed and versatility. This hub features a hybrid architecture, providing one USB 3.2 Gen 2 port capable of 10Gbps throughput alongside three USB 2.0 ports optimized for peripherals like mice, keyboards, and printers. By utilizing independent transmission channels, the device ensures that high-bandwidth data transfers do not interfere with low-speed accessory stability, making it a reliable hub for professional and personal use.
This product is for:
- Remote professionals who need to connect high-speed external SSDs while maintaining stable connections for wireless input devices.
- Students using modern USB-C tablets or ultrabooks who require additional ports for legacy USB-A flash drives and school accessories.
- IT technicians looking for a portable, multi-interface diagnostic tool that functions across Windows, Mac, and Linux environments.
- Content creators requiring a dedicated 10Gbps lane for rapid file offloading without the latency issues common in shared-bandwidth hubs.
- Minimalist travelers who prioritize a lightweight, 32g form factor that fits easily into any laptop sleeve or pocket.

Operating the U3H390S is a seamless plug-and-play experience that requires no driver installation. The 12cm integrated cable provides sufficient flexibility for laptop use while the dual-head connector eliminates the risk of losing separate adapters. Its sleek, painted finish offers a professional aesthetic, and the compact 65.6mm length ensures it occupies minimal desk real estate. The dual-channel design is particularly effective, allowing a 10Gbps NVMe enclosure to run at full speed while a wireless mouse receiver remains perfectly responsive on the adjacent USB 2.0 port.
Compared to standard USB 3.0 hubs that share a single 5Gbps bus across all ports, the DigiFusion U3H390S offers a superior 10Gbps ceiling on its primary port. While many competitors require a separate USB-C to USB-A dongle, this model integrates both into a single tethered unit, preventing accidental loss and ensuring connectivity with any hardware generation. Furthermore, the inclusion of three USB 2.0 ports specifically for peripherals helps reduce electromagnetic interference that can sometimes affect 2.4GHz wireless devices when plugged into high-speed USB 3.0 ports.
Q&A:
- Can I use the 10Gbps port and USB 2.0 ports at the same time? Yes, the hub uses independent channels to ensure that high-speed data transfers and peripheral inputs do not interfere with each other.
- Does this hub support charging for smartphones? While it provides standard bus power for data operation, it is primarily designed for data transfer and low-power peripherals rather than high-speed device charging.
- Is the USB-C adapter removable? The dual-head connector is a permanent, integrated design; attempting to remove or cut the adapter will void the manufacturer's warranty.
- What happens if I plug it into a USB 2.0 port? The hub is fully backwards compatible, but the maximum speed of all ports will be limited by the host's USB 2.0 bandwidth (480Mbps).
- Does it work with the latest Windows 11 and M3 MacBooks? Yes, the U3H390S is fully compatible with Windows 11 and the latest macOS versions, supporting both Type-A and Type-C hardware configurations.
