This issue has already been documented here on the primary koreader repo.

After some investigation, I found the reason for the lack of touch response. The Mobiscribe Wave reports ACONFIGURATION_TOUCHSCREEN_NOTOUCH despite having a functioning touchscreen. This causes KOReader to not register any touch zones in the reader view, making documents unusable via touch.

To implement the fix, I'm opening a PR in this repo, followed by one on the primary koreader repo.
