As said, this is FIXED in 090 at least... I don't see what's your point here in reopening this bug.
Sigh, for starters, it would really help to NOT post reversed patches... :/

(In reply to comment #5) > It obviously isnt updated, sorry, if I got something wrong. Once again - you did post a *reversed* patch, causing all this confusion. See Comment #0.
The issue here is the 6 vs 4 for the *group* permissions. E.g. to use my scanner, I have: /etc/udev/rules.d/91-local.rules: BUS="usb", SYSFS{product}="CanoScan", GROUP="scanner", MODE="0660" This setting up of custom local rules is a *lot* safer than changing the default for groups from read-only to read/write. So I'd suggest marking this bug WONTFIX.
Ok, marking will not fix.

For the benefit of the duplicated bugs, the "="s in later udev versions (assignation vs test for equality) should be: BUS=="usb", SYSFS{product}=="CanoScan", GROUP="scanner", MODE="0660"
