I am getting error message "cdc_acm: probe of 1-1:1.0 failed with error -5" when connecting my cell phone to my laptop. I would be very grateful for any hints and/or help debugging this.

0409 English(US)P.S. I am running this under Fedora Core Development (AKA Red Hat Raw Hide).
P.P.S. I have also reported this to Red Hat - https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=121355
P.P.P.S. I also tried plugging it into a Mac OS X laptop - it recognizes it as a USB modem without any problems.
