Issue Details

My Windows 10 PXIe controller hangs on the Windows loading screen when I have provide any input from a USB device via an EKF CompactPCI USB card in my system. 

For Example:
  • Moving the mouse
  • Typing on the keyboard


You can resolve this issue by disabling USB Legacy Support located in the USB Configuration submenu of the PXI controller's BIOS. Refer to your controller's user manual to access the BIOS Setup Utility, and navigate to the Advanced Setup Menu >> USB Configuration.
