Did you also try the CUPS administration page at <http://localhost:631>? 
Whan asked for credentials, use your own login name and password.

If you can't get to your USB port there as well, you could try first if 
the communication works at all. Use the command

sudo modprobe usblp

and check if you then have a device "/dev/usblp0". If it is there, use

sudo su lp -c 'echo -en "\f" >/dev/usblp0'

to test the printer. This command should just eject one page of paper, 
which is a good enough indication that the communication works.
