Comment 56 for bug 91250

Regression problem with my Nikon Coolpix 990, which works under Dapper (with a long wait for the camera driver to load).

Now doesn't work at all under 7.04/Feisty release.

Camera Import starts as soon as the camera is plugged in to the USB port but I get an error message in the Import Photos window. It is
" An error occurred in the io-library ('Error updating the port settings'): Could not release interface 0 (Invalid argument)."

I appear to have the up to date udev rules, the first four lines are;

# udev rules file for libgphoto2 devices (udev >= 0.98)
#
SUBSYSTEM!="usb*", GOTO="libgphoto2_rules_end"
ACTION!="add", GOTO="libgphoto2_rules_end"

Running "sudo gthumb" appeared to succeed once, but once only. Subsequent attempts have not worked, giving either the error above or attempting to look for the camera at incorrect addresses on the USB bus.
