推荐答案

有几件事情要看:
-原始记忆棒上的数据是真正的PCM数据，还是经过加密的? IE.您可以通过以下方式播放这些数据吗? Windows Media Player，Audacity等?
-USB记忆棒和键盘之间的通信.看来键盘从USB记忆棒中读取了更多值，例如供应商ID或硬件ID，或隐藏的文件.这些数据提供了允许您将其与键盘一起使用的证明.
-您想保护PCM数据用于哪种用途?您是要防止它们与某些PC软件一起玩，还是要使它们在键盘上可以使用?

There are several things to look at:
- are the data on the original stick really PCM data, or are the encrypted? I.e. can you play these data with e.g. Windows Media Player, Audacity, etc.?
- the communication between the USB stick and the keyboard. It looks like the keyboard reads some more values from the USB stick, e.g. Vendor ID or Hardware ID, or hidden files. These data provide the proof that you are allowed to use it with your keyboard.
- for what type of use do you want to protect your PCM data? Do you want to prevent that they are played with some PC software, or do you want to make them usable with your keyboard?
