    Just a shot in the dark, but have you gone into the BIOS and checked the settings there? I know my T400 has the option there to switch powered USB on and off, even though it doesn't really advertise the capability.

    Try power management settings for USB ports in device manager.

    It may be worth a call to Lenovo support.

    If you look in Power Manager (the most recent updated version 3.xx), under Global Power Settings there is a box to check or uncheck titled "Enable Always on USB". Maybe you could try playing around with that?

    Edit: Sorry, I did not see that in your post you had already tried this. Apologies.
