Thanks Hans for the correction! My Epson printer is now detected with the
ulpt(4) driver. However, it's throwing a message code no. 12 and there is
no character device file of ulpt1 created in the /dev directory thus I
could not print.

root@generic:~ # dmesg
...
ugen1.5: <EPSON EPSON UB-U03II> at usbus1
ulpt1 on uhub1
ulpt1: <EPSON EPSON UB-U03II, class 0/0, rev 1.10/2.00, addr 5> on usbus1
device_attach: ulpt1 attach returned 12

root@generic:~ # ls -la /dev/ulpt1
ls: /dev/ulpt1: No such file or directory

I double checked my Xprinter printer and compared the behavior.

root@generic:~ # dmesg
...
ugen1.4: <Printer-58 USB Printing Support> at usbus1
ulpt0 on uhub1
ulpt0: <Printer-58 USB Printing Support, class 0/0, rev 2.00/2.54, addr 4>
on usbus1
ulpt0: using bi-directional mode
ulpt0: offline

root@generic:~ # ls -la /dev/ulpt0
crw-r--r--  1 root  operator  0x7c Apr 10 03:44 /dev/ulpt0

What is this message code no. 12 showing-up in the device_attach() ->
device_attach: ulpt1 attach returned 12? I'm currently looking at this
message code trying to figure-out what's going on.

Thanks,
Archimedes
