The fingerprint censor has returned to functioning, please feel free to cancel or continue to investigate this bug as you feel appropriate. Furthermore, the issue appears to be a broader USB issue, not related to the driver of the fingerprint sensor. I have not inserted or removed any USB devices since before the issue began, but the output of lsusb now shows three more devices: the fingerprint sensor, an internal wireless networking device, and an external flash drive. The current output of lsusb is:

I assume this is the responsible package, although fwupd and libfwupd2 were also upgraded at the same time. The fingerprint sensor has vid 10a5 and pid a305. It is working in Windows (I dual boot the machine) and I believe the manufacturer is CareWe. The attached screenshot shows the sensor's driver version, which matches the CareWe option of the two Windows drivers provided by Acer for my laptop (it is an Acer Swift Go model number SFG14-63). Acer only provides Windows drivers. The fingerprint reader is built into the laptop keyboard. As also shown in the screenshot, the laptop detects the device on boot, but the fingerprint sensor does not appear in the output of lsusb. Also, fprintd-install returns an error: "Impossible to enroll: GDBus.Error:net.reactivated.Fprint.Error.NoSuchDevice: No devices available". According to /var/log/apt/history.log, linux-firmware was updated at 22:02 on 3 July 2025 - the times of my attempted boots are as per the journalctl output in the screenshot. All times are Sydney times. NB I also booted at 20:13, 20:34 and 20:37, using kernel 6.8.0-63, but I have rolled back to kernel 6.8.0-62 (which was upgraded on 1 July and the fingerprint continued working until linux-firmware was upgraded) and lsusb still does not detect the sensor. At 20:36 I installed kernel 6.11.0-29 and all boots after that appear in the screenshot. I am using Linux Mint 22.1 (based on Noble). The package is 20240318.git3b128b60-0ubuntu2.14. I expected to see the fingerprint reader appear in the lsusb output, and for a pop-up to ask me to use the fingerprint reader when I enter a command with sudo into the terminal. Neither happens.
