Can anyone point me to documentation for hcmon driver or service on Windows?

  • What it does?
  • Why warnings in Windows system event log: hcmon, event 0:  "Detected unrecognized USB driver (....)"?   Is this bad? If so, what I need to do to make it recognized?

Hi there, any update on this? What is the effect of "unrecognized USB driver" on hcmon?

Details: observed om Win11 x64 Dell laptop, Workstation 17.6.1

in the system event log: Warning hcmon event 0:

Detected unrecognized USB driver (\Driver\usbfilter).

These events have 40 bytes of binary data attached, how to decode it?

But if you disable the service you may end up with this problem: https://community.broadcom.com/vmware-cloud-foundation/discussion/windows-11-24h2-breaks-usb-connections#bm870af0a8-1b7f-4dac-a541-4f9de2cb0257

Thank you @!Morc001  I am provider of these USB filter drivers.

Would like my driver "recognized" and not to cause any issue to the USB support and this message altogether. 

So, does anyone know what is needed to be "recognized"?  Do any compatibility tests exist?
