workaround so far:
Edit the lsusb AppArmor profile (/etc/apparmor.d/lsusb) to include these
additional paths:
@{sys}/devices/**/usb[0-9]**/bDeviceClass r,
@{sys}/devices/**/usb[0-9]**/idProduct r,
@{sys}/devices/**/usb[0-9]**/idVendor r,
@{sys}/devices/**/usb[0-9]**/maxchild r,
@{sys}/devices/**/usb[0-9]**/rx_lanes r,
@{sys}/devices/**/usb[0-9]**/tx_lanes r,
@{sys}/devices/**/usb[0-9]**/bAlternateSetting r,
@{sys}/devices/**/usb[0-9]**/bInterfaceClass r,
@{sys}/devices/**/usb[0-9]**/bInterfaceNumber r,
@{sys}/devices/**/usb[0-9]**/bInterfaceProtocol r,
You can also simplify with a single wildcard:
@{sys}/devices/**/usb[0-9]**/* r,
Then reload the profile:
sudo apparmor_parser -r /etc/apparmor.d/lsusb
