My Canon Pixma Pro 100s stopped working after installing build 21354 then upgrade build 21364 and still doesn't work. Now I can't no longer get back to build 21343 or other working builds. Any suggestions?
@RubenFi,
As a workaround till they fix the problem with USB you could try using the printer with the Lan or wireless connection, which ,according to the specs, are available on that printer. My PIXMA 882 is connected via Ethernet and works with 21364.
