FYI:

I've noticed strange problems after upgrading to Feisty from Edgy with my USB devices on both my main PC and IBM R51 laptop.
Until I found this thread I couldn't figure out what was going on but I unmodprobing ehci_hcd restored things to how they functioned in Edgy.
I don't think this is bug is restricted to NFORCE 2 as my main PC is an NFORCE4 and the IBM R51 laptop is of course whatever they use.

The main thing I noticed on my NFORCE4 PC was during the boot my USB Creative labs LIVE! 24 External was being recognized but the 'blue light' was not powering on as was normal and I was getting strange sound problems.
After removing ehci_hd everything returned to normal.
I think something is definately off with the ehci_hcd module.
