usb hpoj hotplug problems with HP OJD125xi printer/scanner
Hi
I've been running into problems when trying to set up a Hewlett-Packard
OfficeJet d125xi printer/scanner under linux.
I've checked machine and usb cabling under windows, and it works.
I've checked linux usb communication (usb-storage) with a digital camera
and it works.
I've emerged hpoj cups, no probs. emerge hpoj prints:
* Before starting hpoj you have to set it up with 'ptal-init setup'
so I run "ptal-init setup"
and it fails to detect my usb printer/scanner as follows:
--snip--
Probe for USB-connected devices ([y]/n)? y
Probing "/dev/usb/lp0"...
No device found.
--snip--
strange I thought and checked that modules were loaded ok:
--snip--
scanner 10588 0 (unused)
printer 8832 1
usb-ohci 19784 0 (unused)
usbcore 70848 1 [usb-storage scanner printer usb-ohci]
--snip--
then I found a horror in dmesg,
--snip--
dmesg after "ptal-init setup"

which seems to point to a ptal-mlcd breakdown, which as far as I can see is
a subprocess to ptal-init.
Hmm so I did a cold system start and checked dmesg before and after
"ptal-init setup" and also that the /proc/bus/usb/devices seemed ok:
system cold start: dmesg from usb-ohci printer scanner usb-storage modules:

No problems there as far as I can see, until I run "ptal-init setup". At
which point the whole "Unable to handle kernel NULL pointer dereference
..." shows up i dmesg.
I've tried adding "hotplug" to default runlevel but that only leads to
hanging some process and blocking a clean shutdown, and sometimes the
"ptal-init setup" hangs everything as well.
hotplug hangs on:
runscript.sh
usb.rc
rmmod
I'm running:
openmosix-sources-2.4.20-r6
hpoj-0.90-r1
hotplug-20030501-r2
on a Gigabit GA-7DPXDW+ board with dual athlon MP 2200+, 512MB ram,
Geforce4mx, sb 1024 live.
I've checked bugs.gentoo.org for hpoj and hotplug bugs, but I've found
nothing I can see as related to this.
Has anyone seen anything like this before? I'd appreciate some advice as to
a fix or circumvention technique. Have I missed something vital or might
it be a valid bug?
Thanks
Jimmy
