One workaround I've found is to use an external USB hub. This won't work for everyone I imagine, but I was inspired to try by one of the above comments. It may work for you if, like me:

* most devices work OK with USB2
* you have one device that doesn't (MP3 players seem to be the common one)

In this case plug the MP3 player (or whatever the device is) into an external USB hub (pretty cheap) and try that without having to rmmod ehci_hcd ...

Hope this helps some of you.

Basically fixing this would break suspend for an equally large amount of people.
