This has been unanswered everywhere, both in RH Bugzilla and in the UbuntuForums. Can somebody from development team look into this?Hmmm... okay, so far, so good. Now, have you checked the logs to see if a "mount point" is created in "/media" ? You should see something like:

Nearly same problems with a Sarotech USB 2.0 HDD device.
1) WHEN I TURN ON THE USB EXTERNAL HDD:
usb 4-3: new high speed USB device using address 2 Initializing USB Mass Storage driver... scsi0 : SCSI emulation for USB Mass Storage devices Vendor: Model: Rev: Type: Direct-Access ANSI SCSI revision: 02 Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 0 USB Mass Storage device found at 2 usbcore: registered new driver usb-storage USB Mass Storage support registered. SCSI device sda: 241254721 512-byte hdwr sectors (123522 MB) sda: assuming drive cache: write through sda:
At this step the computer seems to do nothing more. The red led on USB HDD is lighted. Some activity happening.

Dec 3 08:59:30 traveler fstab-sync[3799]: added mount point /media/usbdisk for /dev/sda1
Note the last line - fstab-async adds a mount point (/media/usbdisk) for the disk I just connected. The next thing I do is simply "mount /media/usbdisk" and I have access to my usb drive...

2) LSMOD shows

3) NOTHING HAPPENING, UNTIL I TURN OFF THE USB DRIVE. DMESG SHOWS ERRORS LIKE:

My HDD works for Fedora Core 1 and Windows XP with no problems. It has external power, not powered from USB bus.
