Done, Here is my comment added to the bug:
Scanner (Epson 1240U) still not detected for me with latest rawhide
sane-backends and hotplug installed.
[root at gstpc-fc3 ~]# rpm -q sane-backends
sane-backends-1.0.15-2
[root at gstpc-fc3 ~]# rpm -q hotplug
hotplug-2004_04_01-10
Scanner is not recognized until I execute a script to change
permissions, even if another USB device (USB flash drive) is active.
[root at gstpc-fc3 ~]# ls /dev/usb
ls: /dev/usb: No such file or directory
[root at gstpc-fc3 ~]# ps axf | grep sleep
4124 ? S< 0:00 | \_ sleep 1
4126 pts/2 S+ 0:00 \_ grep sleep
[root at gstpc-fc3 ~]# ps axf | grep libusbscanner
1336 ? S< 0:00 | \_ /bin/bash
/etc/hotplug/usb/libusbscanner
4132 pts/2 S+ 0:00 \_ grep libusbscanner
I try to Acquire in Gimp at this point, and it fails to find scanner.
[root at gstpc-fc3 ~]# cat /usr/local/bin/fixscan
chmod a+w /proc/bus/usb/003/002
[root at gstpc-fc3 ~]# fixscan
Acquire with Gimp now works. No change in above queries.
[root at gstpc-fc3 ~]# ls /dev/usb
ls: /dev/usb: No such file or directory
[root at gstpc-fc3 ~]# ps axf | grep sleep
4210 ? S< 0:00 | \_ sleep 1
4212 pts/2 R+ 0:00 \_ grep sleep
[root at gstpc-fc3 ~]# ps axf | grep libusbscanner
1336 ? S< 0:00 | \_ /bin/bash
/etc/hotplug/usb/libusbscanner
4219 pts/2 S+ 0:00 \_ grep libusbscanner
