Try the following (as root), as a first error localization:
export SANE_DEBUG_MUSTEK=3
export SANE_DEBUG_SANEI_AB306=4
xscanimage mustek
Your scanner *may* work now, because of the additional delay of the
debugging messages. If not, send me the debugging output you get.

This problem was reported by someone before who uses a Pentium-200.
It seems to be a weird timing problem produced by the Mustek
firmware-programmers:
The scanner indicates "ready", but there are still some internal flags
not set correctly. So, when the Linux-machine is fast enough polling
the ISA bus interface, it sends the first command byte before the
scanner's u-controller has redirected the interrupt in the right way.
On my old 386-33, this was never a problem, but since I also have
upgraded to a 586-200, the same effect occurs.
I'll re-send a patch to this mailing list I got from the one who
found this timing problem first (re-checking the patch before).
It basicly adds some delay at the critical positions.

Andreas.
