I've had this issue with various USB devices for years.

Here's one example that used to work on older hardware with Ubuntu installs, but generally not with newer.

I have a SanDisk Sanza Clip mp3 player that I used to use with Rythmbox all the time, but like I said, doesn't work with most of my newer pc's. I think in some cases I was able to disable the ehci module, but I don't have that option anymore with the newer versions of Ubuntu.

Attached is a copy of my lsusb -vvv

When attaching the device, dmesg | tail outputs something like this:

[ 1093.221007] usb-storage: device found at 6

I followed some instructions I found in a forum and tried to:
echo -n "0000:00:1d.0" > /sys/bus/pci/drivers/ehci_hcd/unbind
but all I managed to do was disable my mouse and keyboard (that was fun :P )
