@John: Your steps appear to have gotten the drive connected via the USB 2.0 hub on my client's server. At least the output of lsusb shows it on the same "Bus 001" which is the bus of the USB 2.0 controller. I modified their "USB HDD fix script" to run these commands when they are mounting their backup drive. I will report again once we see if the backup runs at USB 2.0 performance... but so far, looking promising! Thank you! :-)
