     448しばらく動かして値をcamonitorしていると、あるタイミングで止まってしまう。[[br]]
     449camonitorだけではわからず、IOCのasynログを出力してみると、温度レジスタのLSBに0x00が入った時以降、データが出力されなくなっていることが判明した。[[br]]

     546この状態になると、IOCを止めるだけではダメで、USBコネクタを挿抜して再認識させないと復活しない。[[br]]
     547
     548始めは、HIDAPIの方の問題かと考え、pythonでテストプログラムを書いて実行してみたが、LSBが0x00になっても止まることはなかった。[[br]]
     549その時のスクリプトがこれ。[[br]]
