Hi @EZOJ,

Welcome to the HP Support Community!

 

We noticed that this thread hasn't had any updates in a while since your original post; while this is rare, we didn't want this post to remain unanswered, so here's the solution to your query. We hope it helps you and everyone viewing this post 😊

 

If you're encountering the "Unknown USB Device (Port reset failed)" error on your HP ZBook Firefly 14 G7 Mobile Workstation running Windows 11, here are the recommended steps to resolve the issue:

1. Check Device Manager

  • Press Windows + X and select Device Manager.
  • Expand Universal Serial Bus controllers.
  • Look for any device with a yellow warning icon.
  • Right-click the problematic device and select Uninstall device.
  • Restart your system. Windows will attempt to reinstall the driver automatically.


2. Update USB Drivers

  • In Device Manager, right-click the USB device and choose Update driver.
  • Select Search automatically for drivers.
  • Alternatively, visit the HP Drivers & Software page to download the latest chipset and USB drivers for your ZBook Firefly 14 G7.


3. Disable USB Selective Suspend

  • Go to Control Panel > Power Options.
  • Click Change plan settings next to your active plan.
  • Select Change advanced power settings.
  • Expand USB settings > USB selective suspend setting.
  • Set it to Disabled for both battery and plugged in.
  • Click Apply and OK.


4. BIOS and Firmware Update

  • Visit the HP Support site and enter your product name.
  • Download and install the latest BIOS and firmware updates for your system.


5. Try Different USB Ports

  • Test the device in all available USB ports.
  • If the issue persists across all ports, it may indicate a hardware issue.


6. Perform a Hard Reset

  • Shut down the laptop.
  • Disconnect all external devices and power.
  • Press and hold the power button for 15 seconds.
  • Reconnect the power and boot the system.
