Public bug reported:
With apparmor 4.1.0~beta5-0ubuntu5 on a RISC-V Microchip Icicle Kit I
see that the kernel discovers USB:
[ +0.008662] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ +0.007425] usb 1-1: Product: Ultra
[ +0.003688] usb 1-1: Manufacturer: SanDisk

[ +0.011826] usbcore: registered new interface driver usb-storage
[ +0.035775] usbcore: registered new interface driver uas
But lsusb shows not device. Looking as journalctl shows that apparmor is
blocking:
