Canon LBP 2900 not working on ubuntu 14.04 error message devicepath

Question

I did the following:

1. Downloaded and installed CAPT drivers v 2.6 with dpkg.
2. Installed portreserve, gsfonts, gsfonts-other, gsfonts-X11 with apt-get.
3. Ran sudo service cups restart.

4. Then

   sudo /usr/sbin/lpadmin -p LBP2900 -m CNCUPSLBP2900CAPTK.ppd -v ccp://localhost:59787 -E
   

5. Ran sudo /usr/sbin/ccpdadmin -p LBP2900 -o /dev/usb/lp0

6. Ran sudo service ccpd start
7. Ran sudo service ccpd status

8. Ran captstatusui -P LBP290 and got an error message in a window with the title LBP 2900:

   Check the DevicePath of /etc/ccpd.conf
   

The DevicePath line in /etc/ccpd.conf says: /dev/usb/lp0

When I checked /dev/usb, I found only lp1 there, so I changed the entry in the DevicePath line to /dev/usb/lp1.

No difference to the results.

No printing done.

Can anyone help?
