The PEXUSB4DP is a low profile 4 port USB card designed for versatility and performance. Add 4 USB 2.0 ports to a low profile/small form factor (SFF) computer system, to conserve expansion port availability.
It is with regret that I have to report that this device did not work.
The two I bought from different suppliers both caused boot failure a Windows 10 machine. It is difficult to be more specific as the boot failure prevented windows 10 from loading and starting. The Blue screen with Automatic Repair option came up when the card was removed and the machine was rebooted. It ran normally after selecting the restart option.
