Inateck is dedicated to enhancing the digital lifestyle of our customers. The newly-released RedComets series is a product line custom developed by Inateck team to offer solutions for PCIe to USB ports extension. We have all along pursued the highest industry standard to develop each of our products. Utilizing the cutting-edge chips, our engineers designed the circuitry and safety functions of the RedComets U22 PCIe to USB 3.2 Gen 2 Extension card with expertise and craftsmanship. All for providing you with the most professional computer port extension solution.

The card extends six USB Type-A 3.2 Gen 2 ports and two USB Type-C 3.2 Gen 2 ports from a PCIe x 4 card slot. (PCIe 3.0 supported, backward compatible with PCIe 2.0)

The product can offer 20Gbps bandwidth in total. One USB Type-C port and three USB Type-A ports share an independent chip, and each chip supplies up to 10Gbps transmission rate. One USB C port and three USB A ports share a 10Gbps rate when used simultaneously, and the rest four ports share another 10Gbps bandwidth. Each port can reach a 10Gbps rate when used solely.

The extension card is compatible with Windows 7/8/10 (32/64 bit) and Mac OS 10.8.2 and above. It only requires installing a driver which you can download from our official site when operating on Windows 7. Needless to download any driver, it can directly run on Windows 8/10 and Mac OS systems.

The PCIe card is easy to install and draws power directly from the PCIe interface. The card can be used with a motherboard that supports PCIe 3.0 protocol, and is backward compatible with PCIe 2.0. It can function on PCIe x 4, x 8 and x 16 card slots.

The USB Type-A port extended from the card provides power up to 5W, and the USB Type-C port up to 15W. All ports can charge your devices and feature short-circuit protection.

Low profile is not supported.

1. Please contact the motherboard manufacturer and check the information below.

a. Make sure that the PCIe interface protocol is PCIe 3.0 or above.

b. Make sure that the lanes allocated to the PCIe interface are x4 or more. Note that the lanes allocated to a PCIe x4 interface can be x2 or x1.

c. The number of lanes on the motherboard is fixed. When multiple PCIe interfaces are in use, the actual transmission speed for each interface will be lower than its theoretical value. Suppose that there are 16 lanes on a motherboard where there are two x16 PCIe interfaces that support PCIe 3.0. Theoretically, each interface can reach a maximum bandwidth of 128 Gbps. However, when the two interfaces are in use simultaneously, the lanes allocated to each port will be evenly split to x8 with maximum bandwidth being 64 Gbps.

2. Check if the device connected to the PCIe card supports a 10Gbps bandwidth, which includes the device and the cable between the device and the card.

You may consult the device supplier to check if your device support a 10Gbps bandwidth.

You may quickly check if you cable supports a 10Gbps bandwidth with the methods below:

a.Is the cable length less than one meter? Generally speaking, cables that support 10 Gbps bandwidth are demanding in length. A shorter cable can theoretically transmit data faster. Studies have shown that the cable can hardly reach a 10Gbps bandwidth when the cable length exceeds one meter.

b.If you’ve purchased a cable at a very low cost, it’s much likely that the cable won’t support 10 Gbps bandwidth.Sometimes cost determines quality. The cost for a cable that supports 10 Gbps bandwidth is regularly higher than a normal one, and so is the cost.

c.Consult the cable supplier to check if your cable support 10Gbps bandwidth.

3. Check whether other ports on the PCIe card are in use.

The total bandwidth of the 8 ports on the PCIe card is 20Gbps.

One USB C port and three USB A ports share a 10Gbps rate when used simultaneously, and the rest four ports share another 10Gbps bandwidth. Each port can reach a 10Gbps rate when used solely, When these 8 ports are in use simultaneously, the PCIe card will allocate bandwidth intelligently according to the external devices.
