Dual USB 2.0 header expansion Converts a single USB 2.0 9pin motherboard header into two independent 9pin channels, allowing the simultaneous connection of two front USB panels or devices. Driver compatibility No driver is required; supports a wide range of standard USB 2.0 protocols and is compatible with mainstream systems. Quickly identified when plugged into the 9pin header on the motherboard, making it suitable for upgrading and expanding older motherboards. Interference resistance and independent power Uses an amplification chip and filtering capacitors to resist interference. Each channel is independently powered to reduce the risk of data transmission crosstalk. Stable full speed performance Ensures reliable operation of peripherals such as keyboards, mice, and USB drives with a transmission rate of 480 Mbps and full speed performance. Typical applications Upgrade an older desktop to add two accessible front USB 2.0 ports without replacing the motherboard. Connect two front USB 2.0 panels or devices at the same time for enhanced accessibility and reduced cable clutter. Provide reliable USB 2.0 support for peripherals in gaming rigs, workstations, or home PCs where stable performance is required.
