Features: The expansion card uses a solar induced capacitor to ensure the stability of the USB power supply. The main control chip of for NEC using USB3.0 Association is also the third generation D720202 2-port master. It can expand a 19-pin USB3.0 slot for a computer with an idle mini PCIe slot. The theoretical transfer speed is 5Gbps, which is much higher than the 480Mb/s of USB2.0. Backward compatible with USB2.0, USB1.1, USB1.0. It can also be changed to a small 4PIN power supply by taking power from the SATA board. Built-in 19-pin can transfer two USB3.0 port. Compliant with PCI-Express specification version 2.0, xHCI specification version 1.0, USB3.0 SuperSpeed specification version 1.0. Support USB hot plug and pull function, support for Windows XP/2003/Vista/win7/win8/2003/linux, etc., can provide for LINUX driver.
