Block WebUSB on these sites

Setting the policy lets you list the URL patterns that specify which sites can't ask users to grant them access to a USB device.

Leaving the policy unset means DefaultWebUsbGuardSetting applies for all sites, if it's set. If not, the user's personal setting applies.

URL patterns can't conflict with WebUsbAskForUrls. Neither policy takes precedence if a URL matches with both.

For detailed information on valid url patterns, please see * is not an accepted value for this policy.

Example value:

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
