b.Make sure USB device’s power is turned on.
c.Make sure your device power require under 1.5A.
d.Make sure there is no problem with the card installation.
Q 2. Computer failed to start after inserting the USB 3.2 PCI Express card.
Ans: Turn off the computer, remove the USB 3.2 PCI Express card, and try to restart the computer. If the
computer starts successfully, it means that the card has not been inserted into the PCI Express slot
correctly. Please clean PCI golden finger by rubber firstly, then change another PCI-E slot!
Q 3. How to deal with there is a yellow exclamation point on controller?
Ans:a. Please shutdown your PC, move the card to another available slot then disable and enable USB 3.2 driver.
b.Please point on this device then right-check on the mouse. Selecting "Update Driver" to renew USB driver.
c.This exclamation point usually means there is a resource conflict between this card and another card in your system.
Please move the card to another available slot. Restart your computer.
Windows will re-configure itself and re-assign resources. Check your device manager again.
Q 4. The USB cable has been extended and the device no longer works.
Ans: The length of the USB 3.2 cable must not exceed 1.0 meters. Please do not extend the cable or a USB
repeater must be used if the cable is longer than 1.0 meters. The longer cable causes poor performance.
Q 5. Is it possible to connect current USB 1.1/2.0/3.0/3.1 devices to the USB 3.2 PCIe card?
Ans: Yes it works. Device will not obtain the USB 3.2 10G top performance, but depends on your USB 3.0/2.0 device.
Q 6. I could not get USB 3.2 top performance?
Ans: USB 3.2 PCIe Card benchmark performs up to 2000MB/s with NVMe SSD. So please check your USB 3.2
device could satisfy USB 3.2 bandwidth.
Q 7. Will my USB 3.0/2.0 device raises performance when connecting with USB 3.2 card?
Ans: USB 3.2 card provides higher USB communicating bandwidth between PC desktop and USB device.
However USB device implements performance limits on your USB device data throughput capacity itself.
Q 8. Does this card support USB Power Delivery Protocol?
Ans: This USB 3.1 card does NOT support USB Power Delivery Protocol.
To satisfy USB 3.2 20Gb/s Sup highest performance, USB2321C adopts the PCIe Gen3x2 or Gen2x2
interface connector design to support full-power performances (20Gb/s). User has to plug USB2321C
add-on card into PCIe x16 (or x4 above) slot on the mainboard, such as graphics add-on card adopting.
