Reproducing locally, there appear to be a bunch of apparmor denials in
the journal. I believe the lsusb apparmor profile needs a few more
entries.
I was able to work around by editing the /etc/apparmor.d/lsusb to grant
access to sysfs and restarting apparmor.

Title:
Ubuntu 25.05 plucky: lsusb --tree command doesn't works
Status in apparmor package in Ubuntu:
Confirmed
Status in usbutils package in Ubuntu:
Invalid
Bug description:
In Ubuntu 25.05 plucky running (as root) the command "lsusb --tree" it
show lots of "Permission denied" errors followed by the treeaded info
without identifying the connected devices appearing all of them as
"Class=[unknown]" or "Class='bDeviceClass 0x00 not yet handled'". It
works as expected in previous Ubuntu 24.10 oracular version.
Example:
# lsusb --tree

Running (as root) the command "lsusb" (without --tree) it works as expected
detecting and identifying the root hubs and devices connected:
