This is all I get when I attach a USB drive on an FC4 system: Jan 6 21:23:17 treafy kernel: sda: Write Protect is off Jan 6 21:23:17 treafy kernel: sda: assuming drive cache: write through Jan 6 21:23:17 treafy kernel: SCSI device sda: 253440 512-byte hdwr sectors (130 MB) Jan 6 21:23:17 treafy kernel: sda: Write Protect is off Jan 6 21:23:17 treafy kernel: sda: assuming drive cache: write through Jan 6 21:23:17 treafy kernel: sda: sda1 Jan 6 21:23:17 treafy kernel: Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0 Jan 6 21:23:17 treafy scsi.agent[3164]: disk at /devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.0/host1/target1:0:0/1:0:0:0 Jan 6 21:24:30 treafy kernel: usb 4-2: USB disconnect, address 3 Notice that there is no output from udev or fstab-sync (as there should be), so the usb drive doesn't show up on the desktop (though I can manually mount sda1). Why wouldn't udev (and then fstab-sync) react to the presence of the usb device connected as sda1? On another box, same FC4, this device works perfectly. The difference is that the non-working box was upgraded from FC2, while the working box was upgraded from FC3. I'm pulling my hair out trying to discover what I'm missing on the non-working box. Any ideas for what I might be missing? I had to manually add a 'haldaemon' user to get /etc/init.d/messagebus to not complain.
