Testing required for USB printers

Guys, I've recompiled printer.o module which is used in the firmware in order to fix the kernel oopses. But I need a feedback from the users who is experiencing problems with printing with 1.7.5.6-2 firmware and a facing to kernel oops in the logs. Also I need a feedback from other users to whom current firmware works ok.

So, please download the new driver module usingthis link.
Once you've downloaded it please disconnect your usb printer from the router, power it off then on and copy printer.o to /tmp directory on the router (scp printer.o admin@my.router:/tmp)
Once you've copied the file please establish the ssh/telnet session to the router and do the following

Code:

rmmod printer

After that execute

Code:

insmod /tmp/printer.o

Now you can connect your printer back to the router.

After that please execute

Code:

cat /proc/usblp/usblpid

and post the results here. Also try printing anything to see if that works for you.

P.S. You could also copy printer.o to the usb flash driver and execute

Code:

insmod /mnt/usbfs/printer.o

instead to load new driver.

To whom who has problem with printing: guys, if you want to fix the printing problem please perform the testing mentioned. Otherwise the problem will be never fixed - I need a feedback.

Code:

# cat /proc/usblp/usblpid Manufacturer=Lexmark Model=Lexmark Z22-Z32 Class=Printer Description=Lexmark Z22-Z32

The printer is correctly recognized in the status window, but printing in any way (lpr/raw) does not work. With the old printer module the results have been the same.

Just to clarify: I'm trying to track the problem with kernel oopses in the system log. Is there anything strange in the log?
Also, some users reported that ASUS original firmwares are working ok in the printing part, but does not work with custom one. Have you ever tried printing with ASUS firmwares?

As far as I know the system log doesn't show anything suspicious when trying to print and the situation was the same with the original Firmware, but it might be that there have been more error messages in the system log with the original firmware. I'd try that out, but I think it would be better if I printed from the router itself via a ssh/telnet connection, so I can make sure that the networking part doesn't make any trouble. Can I pipe some file through to the LPR, and if so, how?

Please I'm a newbie to this..if you explain how to copy it to TMP and how to conect with a telnet session..I want to try...my HP840C is now not working (it did for one testform..after that..no connection anymore)

Problem

I want to test this, but how can i copy/move the file:
printer.o to the /tpm directory on the router?:confused:
15-04-2004, 21:28

Want to test as well, doesn't look like ssh is running, with my limited Unix knowledge, is required by scp.
Can not use the card slot on the printer as well using ftp, as the new firmware is not accepting these, so stuck to get the printer.o file on the router.

Any suggestions?
15-04-2004, 21:28
Oleg

Ok, I see. :) Wait for the new test firmware.

try this one

http://wl500g.info/showthread.php?threadid=11

ít SHOULD open up a ftp server upon your wl500gs root

never tested this anymore was tested with 1.6.5.3 for the last time..

Guys, try using this firmware. It contains "right" usb printer module. Also it has vi editor compiled in to the busybox.

Oleg!! Perfect....it's working with my HP Deskjet 840C!!

Great Job...

still not working...
i got the same dmesg

and some stackdump

Its a laser printer, but afaik with this new printing daemon i should handle any printer, right?
17-04-2004, 19:47

Yes, it should...

:) i did a test with my printer :

HP 930C, USB port (9101, mode raw) : working fine

The firmware is 1-7-5-6 release 2 ( my router is a WL500b and i used the recovery mode to ulpload this firmware).
I use a "noname" USB hub between the router and the printer.
I have also conneected on this hub :
- a philips webcam PCVC675K : working
- a USB2 HDD (case "connectland", 2.5") : working

I also now have voice, video, file transfer and webcam with MSN Messenger (with the previous firmwares, i had only the webcam!).

Congratulations for your job Oleg.

Tried the test firmware, but unfortunately got exactly the same problem.
Printer is an HP PSC 2210.

You tried it with th IP port and 9101 for USB?
19-04-2004, 12:18
Josephus

There's no need to test it with the print daemon, because it's not starting, and the printer module crashes...

I'm wondering why All-in-One printers not working with this.
(Yeah my Borther printer also a scanner, fax, photocopy, and things like that )

With the standard Asus firmware the printer is working, including the card reader.

1000 THX to OLEG :D :D :D :D

the new driver works 100% with my Epson Stylus Photo R300 :D

Ok, I will try to determine the reason for that. Stay tuned, probably I will ask you for additional information.
26-04-2004, 19:21

Finally what is needed: to whom who has kernel oopses, please perform these steps - boot with printer attached, establish the telnet/ssh session and execute these commands:

Code:

/init/ftpdserver mount -t ramfs none /mnt/usbfs/ cp /proc/ksyms /proc/modules /etc/linuxigd/syslog.log /mnt/usbfs/ stupid-ftpd

You need to have ftp server enabled in the system settings. Probably there will be an errors during the execution of the first command, but this is ok. Also, no USB drive required for this to work. You need to use latest test firmware.

After that you should start the ftp client and connect to wl500g via ftp. Copy 3 files named ksyms, modules & syslog.log to your local drive, compress(zip) them and attach to the reply of this message.
01-05-2004, 09:33
Oleg

Guys, finally it's seems I've found an error in the ASUS stuff. Please try using this firmware. Hopefully it will fix kernel oopses. Please let me know if it's working now.
Regards, Oleg.

Tested the latest firmware (test3). Unfortunately I still have problems, although seems to recognize the printer.

Attached the log with the Oops error.

2 questions.

One question I have, related to published rootfs, do I need to update that as well? If so, how should I do this, as I cannot find any info related to that.

Other question, are the bootloader (2.2) and hardware (1.0) version also important?

Let me know if I need to do some other tests.

Ok, found another piece of shit. Try this one.
For others - no & no.
