USB scanner no longer works for user in 6.7

[johnR]

I recently did a fresh installation of 6.7 on a system previously running 6.4. The USB scanner worked fine with sane and xsane as a user in 6.4 but now it's only detected by root. Obviously I'm overlooking a permission problem but so far haven't found it.

Relevant line from dmesg:

ugen0 at uhub2 port 2 "Ultima USB Scanner" rev 1.10/1.00 addr 2

Relevant line from sane-find-scanner run as root:

found USB scanner (vendor=0x05d8, product=0x4006 [USB Scanner], chip=GT-6816) at libusb:002:002

User is in wheel group and I did "chmod g+rw /dev/ugen0*" to set device permissions as I had them in 6.4:

crw-rw----  1 root  wheel   63,   0 Sep  5 14:58 /dev/ugen0.00
crw-rw----  1 root  wheel   63,   1 Sep  5 14:58 /dev/ugen0.01
crw-rw----  1 root  wheel   63,   2 Sep  5 14:58 /dev/ugen0.02
...
crw-rw----  1 root  wheel   63,   2 Sep  5 14:58 /dev/ugen0.15

Anyone got any ideas how to fix this?

Someone reported the same problem (scanner only identified under the root user) on misc@ and found the solution in the pkg-readme:

Thanks. The pkg-readme had the information I needed.

The scanner is on /dev/usb2 which only had read permission for wheel group.
'chmod g+w /dev/usb2' fixed it.
