this all sounds a bit strange to me...

This seems to indicate two things: Your PATH may not include /usr/local/bin or
you haven't 'rehashed' after uninstalling and installing sane. This should be
easy to resolve. Secondly, USB communication seems to work, otherwise scanimage
wouldn't recognize your scanner.

This again sounds as if USB communication does not work anymore. First,
'acerfirm' is independent of sane, so it should work no matter how you compiled
and installed sane. If it doesn't work there is probably something wrong with
the USB kernel layer (scanner.c is part of the kernel USB layer). The best
thing I can suggest is a reboot or unloading and reloading of all USB related
kernel modules (scanner, usb-uhci or usb-ohci and usbcore). Be sure that the
scanner module recognizes your scanner (you should get something similar to the
dump below in /var/log/messages:
scanner.c: USB Scanner support registered.
scanner.c: open_scanner(0): invalid scn_minor
usb.c: USB new device connect, assigned device number 2
scanner.c: probe_scanner: User specified USB scanner -- Vendor:Product -
You may have to supply the vendor and product ID by hand to the scanner module
- the version I have doesn't recognize my scanner automatically.

Obviously the previous installation used /etc/sane.d. You have modified
sane.conf, so rpm didn't delete the file and directory. You can probably delete
the whole stuff manually, but it doesn't hurt if it's still there.
Still, the problem remains that USB communication in (1) worked and later it
didn't. The only solution I can think of is that you have loaded kernel modules
with different parameters between both tests.
You should first try to get acerfirm to work again. Once you have uploaded the
firmware 'scanimage -L' should report 'FlatbedScanner16' instead of
'FlatbedScanner13'. (You won't be able to scan at all with the original
If scanimage still coredumps you should supply the output. Maybe it makes sense
