What Causes USB Ports Not Recognising Devices?
When USB ports not recognising devices occurs after a Windows update, several underlying issues may be responsible. The most common culprit is driver corruption during the update installation process. Windows updates frequently include optional driver updates for USB controllers, and these can introduce incompatible or corrupted drivers that disrupt communication between your operating system and USB hardware.
USB controller conflicts in Device Manager represent another frequent cause. Multiple USB controllers may clash after updates, creating situations where duplicate or hidden devices interfere with proper USB enumeration. Windows might load incorrect driver versions for different controllers, preventing devices from being recognised properly.
Power management settings also play a significant role. USB selective suspend and other power-saving features may be altered during updates, causing Windows to power down USB ports during idle states or preventing proper device initialisation upon connection. This is particularly problematic on laptops where aggressive power management is enabled by default.
According to Microsoft’s official USB troubleshooting documentation, driver conflicts account for approximately 70% of USB recognition failures following Windows updates.
System file corruption from the update process can damage critical Windows files related to USB functionality, affecting the entire USB driver stack. Less commonly, outdated BIOS firmware may conflict with newer Windows USB drivers, particularly on older systems or ex-corporate machines with locked configurations.
