mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
noble to verification-done-noble. If it does not fix the bug for you,

failed-noble. In either case, without details of your testing we will
not be able to proceed.

Bug description:
  [ Impact ]

   * Upstream commit:
     https://gitlab.freedesktop.org/libfprint/libfprint/-/commit/eaec2339ccaee64b2bdb1d1e27f51ada673e4087

   * Add new Broadcom device IDs in order to reduce the power consumption
     on the target machine.

   * It might consume more power if the IDs are not in the list.

  [ Test Plan ]

   * Install package on laptop with either IDs list below, and check USB_DEVICE/power/control
     is auto or on.

   * usb:v0A5Cp5860*
     usb:v0A5Cp5863*
     usb:v0A5Cp5864*
     usb:v0A5Cp5865*
     usb:v0A5Cp5866*
     usb:v0A5Cp5867*

  [ Where problems could occur ]

   * Should be low because these IDs only affect on the machine with those Broadcom devices and it
     improves the power consumption.
