Hi,
OK, I have solved the problem, as was originally assumed it boils
down to getting the permissions right.
To make Epson 2480 work, there is no need to patch the uscanner.c
or usbdevs files and rebuild that module. I did make that work
though - sort of, now, sane-find-scanner finds an unidentified
device on uscanner0, but scanimage correctly idenfies the scanner.
This is what to do: In /usr/src/sys/dev/usb edit the files usbdevs
and uscanner.c, in usbdevs add a line:
product EPSON 2480 0x0121 Perfection 2480 scanner
and in uscanner.c add the line
{{ USB_VENDOR_EPSON, USB_PRODUCT_EPSON_2480 }, 0 },
after the last EPSON scanner.
I don't know if there is any benefit from using the uscanner
device other than the ability to set permissions for the scanner
only.
Here's the trick:
Create a file /etc/devfs.rules with the following:
[devfsrules=10]
# Allow any user to access usb devices: uscanner and ugen
add path 'usb0' mode 0666
add path 'usb1' mode 0666
add path 'ugen*' mode 0666
add path 'uscanner*' mode 0666
The last line can be omitted if you don't use the uscanner device.
I think it is better to let "others" access rw the scanner device
than to add users to the operator group.
Alternatively, one can create a separate group eg "scanner", then
append "group scanner" to each rule - this might be the best
instead of giving rw access to arbitrary ugen devices.
In /etc/rc.conf add the line:
devfs_system_ruleset="devfsrules"
Then restart devfs. You can unplug and plugin the scanner as
much as you like.
Cheers, Erik
