Restart is needed to allow devices on every USB port

[achataigner]

Tested platform
Ubuntu 22.04

Steps to reproduce

• usbguard service is running and 2 USB ports are available
• Open a terminal and run this command: sudo dmesg -w
• Plug a device on a USB port:
  • dmesg indicates "Device is not authorized for usage"
  • note idVendor and idProduct displayed by dmesg
• Run usbguard allow-device --permanent "$idVendor:$idProduct" => Now the device works correctly
• Plug the device on another USB port

Result
The device is NOT authorized for usage

Expected result
The device is authorized for usage

Remarks

• The device is authorized for usage after restarting the PC.
• Same behavior if I use usbguard generate-policy --no-ports-sn and then restart usbguard service
• /etc/usbguard/rules.conf is ok: there is no "via-port" attribute

Is it expected ?
If yes a message like "PC restart is required to apply completely the rules" could be nice ?
