Public bug reported:

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:

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

# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 002: ID 174c:1153 ASMedia Technology Inc. ASM1153 SATA 3Gb/s bridge
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 002: ID 0a05:7211 Unknown Manufacturer hub
Bus 004 Device 003: ID 1a2c:0c21 China Resource Semico Co., Ltd USB Keyboard

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

  # lsusb
  Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
  Bus 003 Device 002: ID 174c:1153 ASMedia Technology Inc. ASM1153 SATA 3Gb/s bridge
  Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  Bus 004 Device 002: ID 0a05:7211 Unknown Manufacturer hub
  Bus 004 Device 003: ID 1a2c:0c21 China Resource Semico Co., Ltd USB Keyboard
  Bus 004 Device 004: ID 093a:2521 Pixart Imaging, Inc. Optical Mouse
  Bus 005 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
