[Bug 35638] Re: Printer is not detected properly over USB

Sun Apr 20 22:14:36 UTC 2008

Hi Bill,

I found something similar(?)
hal:///org/freedesktop/Hal/devices/usb_device_67b_2305_noserial_if0_printer_noserial
BUT this works for me and leaves a ID Name of Laserjet_4  BUT no way is the
URI the same...I could not fined that length of URI anywhere ... The printer
works; is all I'm interested in now, how to help others is a guess at best,
I have not seen the issues you have in dropping when rebooting,  and till I
replaced the Cable, I could not find the printer at all; how do you address
that issue?  One other thing is We Both have a Laserjet 4 shouldn't the URI
be the same or very similar, for the same product? OR if it is JUST the
Cable we should be the same also...duh...Or am I not seeing something? In
either case we are forcing the LINUX to pass the identifier for the printer
to be recognized. (just like the issue in Windows I needed to select USB
then windows could find the printer)...

I have been printing yesterday and today the Laptop has been turned on and
off everything works.

I other thing when I sent your the WubI Ubuntu 8.04 Hardy Heron web
site...DO it before you unload your windows. I just install it to my other
IBM laptop R51. It installs and leaves a choice to your BOOT ID (you pick
windows or Ubuntu at boot. BUT the big thing is it acts as complete
installation and creates a vurital disk does NOT affect your Hard disk at
all, and leaves Ubuntu name in the Control panel ADD and REMOVE files. NOW
being installed it finds and accepts your total system, printer, laptop keys
and lights your eithernet and or your wireless, video card, any USB stuff
you have. SO you know even before the offical installating where any issues
are THAT IS COOL...IF you have a 3d Nvida or ATI card you will see the WOW
gnome package, also...

Good luck with the Launch Pad effort, how you handle that is (?) but try
anyway, I guess.  Then load the program to check your system with Hardy
Heron. Be aware it has only one site in the USA so a little slow, maybe wait
till tonight to try...I have Warner Cable pretty good in the 500mbs download
range.

Your friend from NC.
