5.25-inch bay hub

The Vszerda U3-110 installs in a standard 5.25-inch CD-ROM bay and adds four USB 3.0 ports to the front panel. It connects to the motherboard through a 20-pin internal header and draws supplementary power from a SATA connector.

GL3520 chipset and power

The built-in GL3520 chipset manages traffic across all four ports with a 900 mA current limit per port. Compliance covers USB 3.0 Super-Speed at 5 Gbps, USB 2.0 Hi-Speed at 480 Mbps and USB 1.1 Low-Speed at 1.5 Mbps.

Copper construction and fit

Copper conductors carry the signals from the front panel to the internal header. The 5.5-inch form factor matches the bay opening, while the SATA power lead and 20-pin cable reach typical motherboard and power-supply locations without strain.

Questions about this item

Will the GL3520 chipset need firmware updates or replacement over time?

The GL3520 chipset is a fixed hardware controller; it has no user-serviceable firmware and does not require periodic replacement.

At what point does the 900mA per-port current limit become the bottleneck?

Each port supplies up to 900mA; connecting multiple high-draw devices simultaneously will hit that limit before the hub’s aggregate throughput does.

How much heat does the hub generate when all four ports run at 5Gbps all day?

The aluminium front-panel housing passively dissipates the modest heat from the GL3520 and 900mA ports; no active cooling is needed.
