    Around 2.6.13, I noticed that EHCI stopped working after a suspend/resume
    (to/from RAM) cycle. So I updated my suspend script to unload/reload EHCI
    each time, which fixed the problem for me. My script still does that.

    Dunno if it's fixed in mainline or not.
    Does unloading/reloading EHCI help you?

    rmmod ehci_hcd ; modprobe ehci_hcd
