Now the interesting bit is that this only happens for multi-function devices. In my case, this is happening on two USB card readers (both work fine in Windows; one used to work fine in Ubuntu on this box before I upgraded, the other is brand new). I have no problems with my iPod Nano, webcam, Palm T|X, nor Olympus camera. Some of these are obviously low-speed devices, but the iPod should be using ehci_hcd, and it's working without a problem.
I've also tried multiple cables. Also, the same cable that was used on one of the card readers worked flawlewssly to connect the Olympus camera.
Well, that didn't work for me. The error changed:
