Re: USB printing

Hey All,
Hi!
I am a relativley newby to linux so excuse a probably foolish explanations but had, long trouble with USB-printing - it now works.


I am unable to use my USB printer with my pismo. I'm running the
latest BenH kernel (2.4.4-pre7)
I have 2.2.18pre21 at the moment - I hope it doesn't matter.


CONFIG_USB=y
# CONFIG_USB_DEBUG is not set
CONFIG_USB_DEVICEFS=y
# CONFIG_USB_BANDWIDTH is not set
# CONFIG_USB_UHCI is not set
# CONFIG_USB_UHCI_ALT is not set
CONFIG_USB_OHCI=y
CONFIG_USB_AUDIO=m
# CONFIG_USB_BLUETOOTH is not set
# CONFIG_USB_STORAGE is not set
# CONFIG_USB_ACM is not set
CONFIG_USB_PRINTER=y
CONFIG_USB_HID=y

seems ok



and with dmesg I get:

printer.c: usblp0: USB Bidirectional printer dev 4 if 0 alt 0

I had to create /dev/usb/lp0 by hand:

crw-rw-rw-    1 root     root     180,   0 Apr 29 20:20 /dev/usb/lp0

at that step I did

mknod /dev/usb/usblp  c 180 0

(might be the same as you did)


When I run ls >/dev/usb/lp0 nothing happens. I ran apsfilter and set

Does anyone have any suggestions of how I can debug this further? I
wonder if I'm missing some other important kernel piece.

Then I went in /etc/fstab and wrote after the line beginning with
"proc ....." the following line

none /proc/bus/usb   usbdevfs  defaults   0  0


That worked for me - I hope it will do it for you

Cheers

Georg
