[sane-devel] "device busy" CanoScanfb636u

Thu Oct 17 21:13:25 BST 2002

Hello!

I have successfully scaned with sane once but next day nothing was right.
The preview picture is always there.
I have now some problems with sane and canoscanfb636u and Mandrake 9.0. My usb 
device is always "device busy"
#scanimage    sane_start: Device busy
#xscanimage   klick buttons and receive similar "Device busy"
#sane-find-scanner find scanner under dev/usb/scanner 0
I scanned successfully. But the next day i received this error-message. 
I have deinstalled usbview, usbutils, scanerdrake, harddrake, hpoj, dynamic, 
dakxconfig.
Stopped devfs, amd , and other services, but i receive always device bussy.

Please help me.
I don't know the cause for this message "device busy"
Before i start xsane i type #modeprobe scanner or
# /sbin/insmod /lib/modules/2.4.19-16mdk/kernel/drivers/usb/scanner.o.gz 
vendor=0x04a9 product=0x2204
