'IOUSBFamily was not able to enumerate a device' HD crash and reinstall

About a week ago, my wife's PowerBook G4 suffered a fatal HD problem...we have all been there...(click click click buzz). Seeings its well beyond its warrantee plus the fact I am fairly handy, I took it upon myself to do the HD replace. Despite carpal tunnel from the 27 screws I had to remove to get the old drive out, the install went rather well. The new drive was in, I booted from the Leopard CD and within 2hrs had a working system...so I thought.
Since my wife kept no backups (despite me telling her too AND the fact this has happened before), I decided to use one of my external WD Passport drives as a Time Machine backup drive for her. Only, instead of recognizing the drive, I get one of several errors in dmesg:
-> IOUSBFamily was not able to enumerate a device.
-> IOHIDSystem: Seize of IOHIDEventDriver failed.
The device is never seen from. If I put my ear next to it, I can hear it wizz up to speed, then click, slow to a stop, wizz up to speed, click, slow to a stop. It does this over and over.
The other weird tidbit is that it seems to only effect mass storage devices. On the right hand USB she has the USB hub plug for the 20" Cinema display, and into that a 5-port USB 2.0 hub. Attached to that is a USB Wacom Intuous 2 tables, a WD 500gb HD, an HP printer, and an Epson printer. In System Profiler, I can clearly see the Cinema hub, the tablet, and both printers, but the WD 500gb drive is missing. Same holds true if I plug the Passport in. Also, she has a 196gb Firewire drive plugged in through the Cinema display that works fine. Also, plugging either USB external drive into my MacBook Pro works fine.
So far I have tried repeatedly booting and booting off the Leopard DVD. I am about to try resetting the PRAM. Does anyone else know what I can try, or perhaps knows whats causing only the USB storage devices to not show up? I am really hoping this is not a problem with the internal USB components.

Hi, Michael. An extremely common problem in all Powerbook G4 models is the inability to supply enough power to bus-powered external hard drives. If you were plugging the WD drive directly into one of the Powerbook's USB ports and the drive has no AC power supply of its own, that's undoubtedly your problem. Typically the drive will spin up and appear to be operating under those circumstances, but it can't be mounted on the desktop or used. The solution is to provide it with power from a more potent source, such as an AC adapter if if one is available for the drive, or a powered hub.

I believe this could in fact be part of the issue. I first had the bus powered WD Passport plugged into a 5-port hub that was plugged into her Cinema display. I then tried to rule out the 5-port hub by plugging directly into the Powerbook G4. When this didn't work, I just assumed something was wrong with the drivers/kernel since both the attempts yielded the same result. Plugging the drive directly into the Cinema Display solved the problem. Its now mounted and ready to rock.
The only other thing that's confusing me now, however, is why the WD 500gb MyBook drive isn't working. It too is plugged into the 5-port USB hub, but its also self-powered through a power brick. Its also plugged into the same 5-pot USB hub that the two printers are using (an HP PCS-1100 and an Epson 1280). The printers are working, the drive is not. I am going to try to dig up the power brick for the USB hub to see if that might help.
Thanks for helping me figure this out.

Hi again, Michael. Search the Powerbook forums for the word "MyBook", and I think you'll find one or more threads in which it's explained why you're going to be very sorry you bought that drive. I don't recall how it goes myself, but I've seen it quite recently.
As for the Passport, the insufficient-bus-power issue is indeed your problem, and you've solved it.
