I just noticed the following firmware update for the NEC USB 3.0 controller for the Thinkpad W510 at http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-75165

Version 3.0.2.5

    * (New) Initial release
    * (New) Mass Storage Class UAS (USB Attached SCSI) is supported.
    * (Fix) Added the workaround of xHCI Driver Unload Problem.

I don't know what exactly this workaround refers to, but it sounds a lot like this bug. The release date is 2010/05/17.I believe my original firmware version was 3.0.2.1. I haven't yet tested this in Ubuntu, since I'm mostly running in Win7 for now. I suppose that to properly test this, I'll have to remove the

SUSPEND_MODULES="xhci"

line from the file

/etc/pm/config.d/unload_modules.
