Yes, the MX850 was connected via USB.

Yes, because I couldn’t successfully build the 2009-03-24 nightly  
snapshot.

It was connected by USB. I have tried it connected directly via  
Ethernet cable (i.e. no hub or switch). I will give the details in a  
future e-mail.

The Canon Scangear stuff was installed when I did the testing two days  
ago:

The Canon Scangear software does work. Of course, the Scangear  
software doesn’t allow for scanning from the command line, which I  
would like to be able to do.

The Canon Scangear software is not currently installed, and was not  
installed when I tested earlier today:

scanimage -L &> scanimage-L.log
always seems to succeed, and finds
device `pixma:04A9172C_21B0DA' is a CANON Canon PIXMA MX850 multi- 
function peripheral

scanimage -d pixma:04A9172C_21B0DA -T &> scanimage.log
always hangs, always seemingly at the same place, and only rarely can  
the process be killed.
