It appeard to me that the kernal patch for the LiDE20 added support to 
uscanner.  I think my problem is different since I know my Canon 1240U is 
NOT supported by uscanner but is purported to be with plustek.

Regarding uscanner, I'm running 5.1R and made sure it was NOT loaded before 
I tested.

I interpert the test results in my earlier post to imply: that uscanner.o is 
not loaded nor involved and plustek finds an unknown named scanner with the 
expected vendor-ID and prod-ID (0x04a9 and 0x220e) at 
libsub:/dev/usb0:/dev/ugen0 but then does not belive it to be using the 
expected chip set.

I'm guessing that uscanner is not and should not be involved and that 
plustek should recognize the Canon 1240U but has a bug.

I hunted around for plustek* to see if I could tell anything from the source 
but I havn't found it.
