![EgisTec 0570 指纹传感器 - fprintd-enroll 不工作](https://linux22.com/image/194468/EgisTec%200570%20%E6%8C%87%E7%BA%B9%E4%BC%A0%E6%84%9F%E5%99%A8%20-%20fprintd-enroll%20%E4%B8%8D%E5%B7%A5%E4%BD%9C.png)
我有一个 Acer Swift 3 (SF314-57) 跑步机,它有一个 0570 LighTuning Technology Inc. EgisTec 触摸指纹传感器。最新的 libfprint 版本 (v1.92.1) 刚刚提供了对该设备的支持,所以我自然一直在努力让它工作。
我从官方 arch 存储库安装了 fprintd 软件包,但是,当我尝试注册指纹时,它只是“卡住”,并带有Enrolling right-index-finger finger
闪烁的光标,并且无论尝试扫描我的指纹多少次,它都不会给出任何形式的信息。表明某事正在发生。
我的系统可以看到该设备并且 fprintd.service 正在运行:

我得到的唯一错误journalctl -f -u fprintd.service
是:
fprintd[6957]: Failed to clear storage before first enrollment: Device has no storage.
(我应该补充一点,我的磁盘有大约 50GB 的可用存储空间,所以问题不在于我的磁盘存储空间 - 我假设是读者的存储空间?)
当我从源代码构建 libfprint 时,使用meson compile
然后meson test
,并尝试使用示例进行注册,它显示:
This program will enroll the selected finger, unconditionally overwriting any print for the same finger that was enrolled previously. If you want to continue, press enter, otherwise hit Ctrl+C
Choose the finger to enroll:
[0] left thumb
[1] left index

[3] left ring
[4] left little
[5] right thumb
[6] right index

[8] right ring

有人知道发生了什么事吗?我觉得我错过了一些明显的东西,但我不知道是什么。
