Port Monitor questions

[Justin Huang]

Hi,
I modified BCP program and copy the compiled bcp monitor to /usr/lib/cups/monitor/pm. Then I modified the PPD file by adding a line and then restart cupsd:
*cupsPortMonitor usb/USB Printing: "pm"

I let the port monitor create a file in /tmp folder so I can check the file to see if the monitor had been launched. After submiting many jobs to the printer, I still cannot see the log file there. The print jobs seem to bypass the port monitor and go directly to the backend.

Did I do anything wrong?
