Hi! I use trackbal(Logitech Cordless Optical TrackMan) and when i open kcontrol->Peripherals->Mouse->Cordless Optical TrackMan i see message: "You have a Logitech Mouse connected, and libusb was found at compile time, but it was not possible to access this mouse. This is probably caused by a permissions problem." How i can repair this problem or what i must read to resolve this problem. Debian Sarge KDE 3.4.0 Thanks in advance. ___________________________________________________ . Account management: https://mail.kde.org/mailman/listinfo/kde. Archives: http://lists.kde.org/.
