Press Windows Key + R , type appwiz.cpl , and hit . Locate PCoIP Client or HP Anyware Client in the list. Right-click it and choose Uninstall .

When system drivers fail, the local component store may be corrupted. Windows can repair basic system driver file integrity automatically. fusbhubsys

In conclusion, fusbhub.sys is a vital system file that plays a crucial role in managing and facilitating communication between USB devices and the operating system. While it may seem mysterious at first, understanding its purpose and functionality can help you troubleshoot issues and optimize your computer's performance.

USB hubs are devices that expand a single USB port into multiple ports, allowing you to connect many devices to one computer. The usbhub.sys driver provides a "generic parent facility" within the USB bus driver architecture, enabling the operating system to detect, manage, and communicate with every USB device connected to your system.

The primary role of fusbhub.sys is to act as a virtual USB hub driver. When you use software like FlexiHub to share a USB device (like a printer, scanner, or security dongle) across the internet or a local network, this driver manages the connection between the physical hardware and the virtualized environment on the remote computer.

: A significant vulnerability (CVSS 6.1) was identified in FlexiHub 5.5 involving the IoControlCode handler (specifically function 0x220088 ).

It intercepts communication at the hardware layer between your local Universal Serial Bus (USB) controllers and your operating system.

In standard computing, the Windows operating system relies on native drivers like usbhub.sys or usbhub3.sys to manage physical connections. Virtual and remote environments require an extra layer to forward those signals to a hosted desktop. Press Windows Key + R , type appwiz
