Looks ok. So it's at least detected by the Linux kernel scanner module.

Did you change anything in mustek_usb.conf? The scanner shouldn't be
detected at all by default.

You don't need this. It's only for SCSI scanners.

We are trying to autodetect the scanner ...

now trying all possible device names (e.g. /dev/usb/scanner0)

We found something that can be opened...

Ha, thanks for pointing to this typo :-) Will fix this in CVS. ^^

You seem to have a Linux kernel version < 2.4.8. Is this correct?
This means you must set the scanner type manually (as described in the
manual page).

Ok, now manually ...

That's right...

> [mustek_usb] sane_init: config file line 27: option 1200usb_plus is unknown

Yes. There is no option named "1200usb_plus". All the options are
listed in the manual page. Really all of them :-)

However, if you like to hear your scanner in action, you can use
"option 1200cu". You won't scan with this but maybe your scan slider
moves at least. Please keep your fingers at the power plug and remove
power if the slider bumps at the end of the scanner. Could you please
check if the slider moves at all and if it moves to half of the page
if you try to scan half the page?

Ignore this.

Try:

/dev/usb/scanner0
option 1200cu
