Key benefits Hardware whitelist mechanism: The card includes a builtin hardware based USB port whitelisting feature to control which USB devices can be used. This is suitable for users who want to enforce USB access policies; guidance and tutorials on USB port whitelisting are commonly available. Performance by PCIe version: Throughput depends on the PCIe slot. On PCIe 1.0, you can expect around 140 M/S; on PCIe 2.0, the speed is over 300 Mbps, providing better performance in newer systems. Compact and flexible power options: The card is designed as a small PCIe expansion device and offers flexible power connections, with options for a small 15pin PCIe style connector or a small 4pin floppy drive style power supply. PCIe compatibility and reliability: This product is intended for PCIe standard slots and must be plugged in to operate, ensuring proper connection and function. Small form factor design: The device's compact size makes it suitable for small builds and spaceconstrained environments without sacrificing core functionality. Product details and capabilities Function: PCIe expansion card with an integrated hardware whitelist mechanism to manage USB device access. Compatibility: Designed for PCIe standard slots; compatible with systems that support PCIe. Size and form factor: Small PCIe expansion card with a compact footprint. Power supply: Supports a small 15pin PCIe style power connector or a small 4pin floppy drive power connector. Performance: Speed is approximately 140 M/S on PCIe 1.0 and over 300 Mbps on PCIe 2.0. Usage scenarios Scenario 1: In a secure office or lab environment where USB device control is essential, enable USB port whitelisting to prevent unauthorized peripherals and protect data. Scenario 2: In a home or small business PC with a PCIe 2.0 slot, leverage higher throughput for USB devices while maintaining controlled access. Scenario 3: In an older or compact system, use the flexible power options (15pin PCIe or 4pin floppy drive connector) to accommodate available power connections without requiring additional adapters.
