NO NEED TO DO THIS!!! Sane-1.0.10 includes all available updates so far!!!

Hmmm, either use iscan or SANE-1.0.10 with the Plustek backend installted
or you will run into trouble as iscan is AFAIK based on an older SANE-Version.

Have a close look at this output, as here is one answer to your problem!
libusb:001:004 is the device!

no too bad so far, as this is the default behaviour, when starting scanimage
without parameters... it simply scans a picture and sends the data to 
stdout - try scanimage > picture.pnm

Almost nothing!!!
First make sure, that when using libusb for accessing the scanner, you have
at least these lines in your plustek.conf:
[usb] 0x04b8 0x011d
device auto

Next thing is, that you MUST have access as normal user to this device.

Another thing that makes me wonder is the description of your plustek.conf,
as it says device /dev/usb/scanner0 and the output of scanimage -L says:
libusb:001:004
this is unusual!!!
Could it be, that you have two different versions installed on your box?
I suggest here to remove at least iscan and all other sane rpms, then
reinstall the sane-1.0.10 stuff from scratch...
After that try using sane-find-scanner as normal user, if that works,
check scanimage -L and then
xscanimage and or xsane should work too...

Cheers
