Scanner rights messed up: please help!
No one responded to my last post, so I'll try it again. A previously working scanner is no longer accessible for the group "scanner". It works under root. Something seems to have changed in a recent dist-upgrade.
The device is listed as:
T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 1.00 Cls=ff(vend.) Sub=ff Prot=ff MxPS=64 #Cfgs= 1
P: Vendor=04b8 ProdID=0109 Rev= 1.07
S: Manufacturer=EPSON
S: Product=Expression1640XL
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 2mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
but ls -la /proc/bus/usb/001
total 0
dr-xr-xr-x 2 root root 0 2006-08-24 11:35 .
drwxr-xr-x 6 root root 0 2006-08-24 11:35 ..
-rw-r--r-- 1 root root 43 2006-08-24 11:35 001
-rw-r--r-- 1 root root 50 2006-08-24 09:36 002
where 001:002 used to be root:scanner, allowing scanning by users in that group. Not any more.
I don't know where the rights for this device are beging set, can someone suggest a way to solve this problem? I did find someting about setting rights in the documentation for usblib, but have never had to intervene in this regard before. And am not sure if that is the problem anyway.
This is the second or thrid time that dist-upgrade has broken my system because of a rights problem. First cups, more recently automounting in KDE, and now the scanner problem. I really like debian, but when printing or scanning or access to a usb stick suddenly stops working my debian system becomes useless to me.
