Hi Wilhelm,
thanks for your reply - I made some progress in this issue however
still did not fully succeed.
- First step as you told me: make clean, configure --enable-scanbuttond,
make, make install, copy manually the
old backends to /usr/local/lib/scanbd/scanbuttond as described in the
README (this all with the 1.5.0 version of scanbd).
- Starting scanbd -f -d7, I first got a "scanbd: Can't get the scbtn
device list" error.
- I edited /usr/local/lib/scanbd/scanbuttond/backends/meta.conf, making
it contain the single line "genesys" which was missing before.
- Then the LiDE-60 was recognized by the old backend, together with its
four buttons !
- However, scanbd finally stumbled on an assertion:/

Aborted
Of course there are only 4 buttons physically, plus one hidden reset
button. Now i am unsure whether simply to edit the source code in order to
remove the assertion. My feeling is it might work then.
