I upraded to KUbuntu 9.04
Since Ubuntu 8.04 I'm using this udev rule here to give rw permissions to all
users.
-------------------
#Set permissions, allowing normal users to have read- and write-access to the
device
ATTRS{idVendor}=="07c0", ATTRS{idProduct}=="1113", MODE="666"
ATTRS{idVendor}=="07c0", ATTRS{idProduct}=="1114", MODE="666"
-------------------
After I did the upgrade the permissions are gone, only running my apps with
sudo works!
The rule for libusb in /lib/udev/rules.d/50-udev-default.rules
# libusb device nodes
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device",
NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", MODE="0664"
causes the trouble. The devices cannot be accessed by libusb for non-
root users no matter what privilegs are set on the individual device
node.
Thanks
Eberhard
