The is an internal USB PCI expansion card that adds four additional USB ports to a computer's motherboard.

In many electronics schematics (especially for amplifier boards or voltage regulators), you might see a label like XH-39.0 or XH-V1.39 .

Many connection stability issues stem from the operating system cutting power to the USB hub. In , expand Universal Serial Bus controllers . Right-click your main USB Root Hub and select Properties . xh-39.0 driver

When this driver fails, it’s often due to a Windows update bug or a system file issue. In the , the USB controller will be flagged with a yellow triangle. Viewing its properties will likely reveal an error message:
