[sane-devel] Kernel claiming device?

[Kerry Menzel]

Hi,

 

I just bought an Avision AV220 scanner and I'm trying to get it going on

RedHat ES 4 (2.6.9-5.EL). When I run sane-find-scanner, it finds the

device at libusb:002:005. When I run scanImage -L, no scanners are

detected. I put things in debug mode and I got the following output. I'm

suspecting that the kernel has laid claim to the scanner. How do I get

SANE to control the scanner or should I do something else????

The permissions for /proc/bus/usb/002 are 777 and 666

for /proc/bus/usb/002/005

 

Thanks for the help!

Check that you have permissions to write to 002/005 and, if you don't,

that you set up hotplug (http://linux-hotplug.sourceforge.net/)

correctly.

USB error: could not claim interface 0: Device or resource busy

[sanei_usb] sanei_usb_open: libusb complained: could not claim interface

0: Device or resource busy

[sanei_usb] Maybe the kernel scanner driver claims the scanner's

interface?
