Hello!

I use Linux, Suse 10.1.
In JavaxUsb.h the USBDEVFS_PATH is set to /proc/bus/
usb. But the path to my usb-device-files is in /dev/
bus/usb!

Then I have the problem, that i can only access to usb-
devices, when I start my program as root, otherwise i
have no permissions to the devices. Are there any
solutions for that problem. Setting permission each
time when I attach an usb-device is very annoying.

Sorry for my rusty english

    This is a bug, for newer kernels the usbfs filesystem has
    been moved to /dev/bus/usb (via udev). Patch to
    javax-usb-ri-linux will be applied soon.

    For information regarding permissions you need to look at
    the udev documentation, as that is what controls
    creation/configuration of the /dev/bus/usb/ nodes.

    This should be fixed in CVS, please try the code and see if it works for you.
