Hello again,

1. First of all: I very much appreciated your input and your suggestions. I  
experienced the (very agreeable) feeling of working together to get rid of a 
problem.

2. Thanks for your scenario "after the fact" of the procedure.  From it, I 
have learned that libusb and libusb-devel are not part of the openSUSE distro, 
at least not in the versions required.  However, I am somewhat surprised that 
a "devel" version should be required for installing a printer. But I happily 
accept this as a fact.

3. Thanks also for explaining the need for membership of the 'sys' and 'lp' 
groups. 

4. Contrary to your opinion you are, in comparison with me, most certainly an 
expert ! 

5. You have caused to inconvenience at all. On the contrary, you have 
eliminated an inconvenience that has kept me thinking and trying (off and on)  
for three months. 

Finally, I want to thank you again for your expert help and the the speed of 
your responses.

Sincerely,

Hans Schreuder.
