私は0570 LightTuning Technology Inc. EgisTecタッチ指紋センサー付きのAcer Swift 3（SF314-57）ランニングマシンがあります。最新のlibfprintバージョン（v1.92.1）は、このデバイスのサポートを提供しているため、自然に動作するように努めてきました。
公式のアーチリポジトリからfprintdパッケージをインストールしましたが、指紋を登録しようとすると、点滅しているカーソルでEnrolling right-index-finger finger「停止」して何度も指紋をスキャンしようとすると、何の形式も提供されません。情報の。何が起こっているかを示します。
私のシステムでデバイスを見ることができ、fprintd.serviceが実行されています。

私が得る唯一のエラーjournalctl -f -u fprintd.serviceは次のとおりです。
fprintd[6957]: Failed to clear storage before first enrollment: Device has no storage.
（私のディスクに約50 GBの空き容量があることを追加する必要があります。したがって、問題は私のディスク容量ではありません。リーダーのストレージ容量であると仮定しますか？）
meson compilethenを使用してソースからlibfprintをビルドし、meson test例を使用して登録しようとすると、次のようになります。

何が起こっているのか知っている人はいますか？何か明らかなものを見逃しているような感じがしますが、それが何なのかはわかりません。
