CX5400 all in one, usb problem, FC4
 

Hello,

I am now using Fedora Core 4 and my CX5400 no longer works. The /var/log/messages reports this error:

Oct 8 08:56:54 smith kernel: usb 2-1: usbfs: interface 1 claimed by usblp while 'iscan' sets config #1

Does anyone know what this means and how to fix it ?

More detailed information is below.

Thanks,

Pete,

ok
 

I just fixed this. I found your message when I was trying to figure it out still.
Anyway, I had usblp in the kernel, not as a module. I rebuilt the kernel with the usb printer option as a module.
I'm not sure if that is an issue for you or not.
When I turned on the printer (I have a stylus cx 5200) dmesg said the same thing, "registering new driver blahblahblah usblp0, enjoy not being able to use your scanner, sucka"
Actually, it said:

usb 4-1: new full speed USB device using uhci_hcd and address 3
drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 3 if 1 alt 0 proto 2 vid 0x04B8 pid 0x0801
usbcore: registered new driver usblp
drivers/usb/class/usblp.c: v0.13: USB Printer Device Class driver

So then, I did

#modprobe -r usblp

that removed the printer module.

usbcore: deregistering driver usblp
drivers/usb/class/usblp.c: usblp0: removed

then I fired up "kooka" and my scanner was detected right away. Then, I wanted to print something, and so I turned off the scanner/printer and turned it back on, and then it automagically re-registered the usblp driver.

(kooka is the kde windows manager scanner program that I use.)

Thanks very much for the reply! I'll give it a try this weekend.

Resolved
 

The problem is resolved by upgrading to the CVS version of libsane. It is not necessary to remove usblp from the kernel. Note that, iscan contains code from libsane, so xsane should be used instead.
