The printer, as it seems, is recognized:

printserver:~# lsusb
Bus 001 Device 002: ID 04b8:0005 Seiko Epson Corp. Stylus Printer
Bus 001 Device 001: ID 0000:0000

I was searching [1] in Internet and I've followed these steps:

printserver:~# mkdir /dev/usb
printserver:~# mknod /dev/usb/lp0 c 180 0
printserver:~# ls /dev/usb -l
total 0
crw-r--r--  1 root root 180, 0 Dec 14 09:48 lp0

but the device can't be open:

printserver:~# escputil -u -i -r /dev/usb/lp0

Cannot open /dev/usb/lp0 read/write: No such device

CUPS reports the same problem:

StC65 EPSON Stylus C64 - CUPS+Gimp-Print v4.2.7
Description: Epson Stylus C65
Location:
Printer State: processing, accepting jobs.
"Unable to open USB device "usb:/dev/usb/lp0": No such device"
Device URI: usb:/dev/usb/lp0

I've notice the device /dev/usb/lp0 is gone after the boot :-S

printserver:/dev# ls /dev/usb -l
ls: /dev/usb: No such file or directory

and I get this message from lp:
lp: driver loaded but no devices found


Thanks to both for your answers.

Regards,
Daniel
