[1.] One line summary of the problem:
Problem using Epson Stylus CX3200 printer/scanner.

[2.] Full description of the problem/report: Printer/Scanner is attached
to UBS. When booting with printer turned on the output to dmsg is as
below. If the printer is turned on after booting the printer and scanner
are found, but neither is usable. During setup with RedHat's set up tool
the printer worked as did the scanner when set up under XSANE. Neither
printer nor scanner are accessible after reboot, with printer's error light
on. 

[3.] Keywords (i.e., modules, networking, kernel): Epson printer-scanner,
UBS. 

[4.] Kernel version:
Linux version 2.4.18-14 (bhcompile@astest.test.redhat.com) (gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)) #1 Wed Sep 4 12:13:11 EDT 2002

[7.7.] Other information:

[X.] Other notes, patches, fixes, workarounds::
From "http://www.w3.org/TR/xhtml-basic/xhtml-basic10.dtd"
"You have to remove the following from the "drivers/usb/scanner.c" file in the
kernel source:
    if (dev->config[0].bNumInterfaces != 1) {
        info("probe_scanner: Only one device interface is supported.");
        return NULL;
    }
"Then you have to recompile, install, and reload the "scanner.o" kernel module
 (the commands have to be executed as "root", we assume that the kernel source
 code is in the "/usr/src/linux" directory):

    cd /usr/src/linux 
    make modules
    cp drivers/usb/scanner.o /lib/modules/&lt;Linux version&gt;/kernel/drivers/usb/
    rmmod scanner
    modprobe scanner vendor=0x04b8 product=0x0802

    After having done so you can configure SANE to use the
    CX3200 with the "epson" scanner driver, it is
    compatible to the Epson Perfection 1200U.
