[embarrased]
the printer had (somehow) shut down at some point in the afternoon,
thus it was not listed, as pete z. pointed out.
now, after restarting it, it does in fact seem like the
printer is indeed now detected by the printer module:
bash# lsmod | egrep "usb|printer|Module|uhci"
Module Size Used by
printer 4928 1
uhci 22144 0 (unused)
usbcore 49664 1 [printer uhci]
bash#
i am astonished and embarrased
to report that things just work now,
after two *d@mned* days of fiddling with
this problem in various ways.
sorry for bothering you guys - now ... what _really_ bothers
me now is that i have no idea what is the right thing to
do...
i noted the modules running (uhci), and
rebooted the linux box ... hmmm, it does not work.
the ptal daemos are there ... yet the printer module is *not*
used:
bash# get ptal
root 670 0.0 0.1 1864 612 ? S 00:32 0:00
/opt/hpoj-010515/bin/ptal-mlcd usb:0 -device /dev/usb/lp0
root 672 0.0 0.1 1372 404 ? S 00:32 0:00
/opt/hpoj-010515/bin/ptal-printd mlc:usb:0 -like /dev/lp0
bash# lsmod | egrep "usb|printer|Module|uhci"
Module Size Used by
printer 4928 0 (unused)
uhci 22144 0 (unused)
usbcore 49664 1 [printer uhci]
bash#
like this, lpr just "sucks" print jobs into oblivion.
i tried rebooting the printer ... this shows up ...
May 17 00:38:04 tcb kernel: usb.c: USB disconnect on device 4
May 17 00:38:48 tcb kernel: hub.c: USB new device connect on bus1/2, assigned

May 17 00:38:48 tcb kernel: printer.c: usblp0: USB Bidirectional printer dev 5
if 0 alt 0
but nothing, the daemons come up,
bash# get ptal
root 1812 0.0 0.1 1864 612 ? S 00:38 0:00
/opt/hpoj-010515/bin/ptal-mlcd usb:0 -device /dev/usb/lp0
root 1814 0.0 0.1 1372 400 ? S 00:38 0:00
/opt/hpoj-010515/bin/ptal-printd mlc:usb:0 -like /dev/lp0
bash#
but the printer is still unused:
bash# lsmod | egrep "usb|printer|Module|uhci"
Module Size Used by
printer 4928 0 (unused)
uhci 22144 0 (unused)
usbcore 49664 1 [printer uhci]
bash#
looking at the /var/log/messages, i am going to try to reconstruct
what happened before, the only interesting things that happened are:
May 16 17:34:06 tcb kernel: usb.c: USB disconnect on device 2
[must have been when the printer shut itself off?]
then ... i am not sure what happened here to trigger this (kernel
autoclean of modules?):
May 16 21:53:02 tcb kernel: usb.c: deregistering driver usblp
May 16 21:53:02 tcb kernel: usb.c: USB disconnect on device 1

May 16 21:53:16 tcb /etc/hotplug/usb.agent: ... no drivers for USB product
0/0/0
and then, this (i'm sure about this) must have been a little bit ago
when i got tipped that the printer was not connected and printing
worked:
May 17 00:19:32 tcb kernel: hub.c: USB new device connect on bus1/2, assigned
device number 6
May 17 00:19:32 tcb kernel: usb.c: USB device 6 (vend/prod 0x3f0/0x11) is not
claimed by any active driver.
May 17 00:19:32 tcb kernel: usb.c: registered new driver usblp
May 17 00:19:32 tcb kernel: printer.c: usblp0: USB Bidirectional printer dev 6
if 0 alt 0
and i cannto reproduce the situation.
i tried unloading printer and uhci, then starting the printer
and various other things ... printer is still unused:
bash# lsmod | egrep "usb|printer|Module|uhci"
Module Size Used by
printer 4928 0 (unused)
uhci 22144 0 (unused)
usbcore 49664 1 [printer uhci]
bash#
thank you for your patience ...
if you have any ideas, please let me know. to finish up, here
is the /proc/bus/usb/devices:
