As with any .0 release, proceed with caution. Users on the developer forum have reported two main issues in the first 48 hours:
Symptoms: Device Manager shows a yellow exclamation mark with Code 28 (drivers not installed). xh-39.0 driver
Solutions:
No. The genuine XH-39.0 driver is a legitimate USB controller driver. However, malicious files can be named "xh-39.0.sys" to disguise themselves. Always verify the digital signature: Right-click driver file → Properties → Digital Signatures – should show Microsoft, Intel, or AMD. As with any
If the above fails, use the hardware ID: Flow control:

In technical contexts, "XH" typically stands for eXtensible Host Controller Interface, the standard for USB 3.0 and later.

However, unlike mainstream drivers (e.g., NVIDIA or Realtek HD Audio), the XH-39.0 driver is frequently a generic identifier used by Windows Update or third-party driver tools when the exact hardware ID cannot be resolved. It is also sometimes associated with:
