Are you running the latest kernel? 2.6.11-1.14_FC3 is it. Well, apparently the new kernel may have introduced some issues into USB - see bug #154690 as an example. Though admittedly it is somewhat in reverse of what you are experiencing, it might be related. According to one report, there is a new kernel in updates-testing (2.6.11-1.20_FC3), that helped the original reporter of that bug. The other solution that I have been using is to simply revert back one kernel when I plan to play with USB devices to 2.6.10-1.770_FC3.... HTH, --Rob
