Dear list. I'm not sure if this belongs here or on the ACPI list. Please forgive. Sometimes when I resume my ThinkPad X200 (Core 2 Duo, 8.0-RELEASE, amd64), my USB ports don't come back online - that is, no power to things that I plug in and nothing shows up in dmesg. Reboot fixes it. It doesn't seem entirely consistent, sometimes USB is fine after suspend, sometimes it isn't. I'm trying to see if I can find some rhyme or reason as to when this occcurs so I can file a bug report and work with someone to get this fixed, but in the mean time is there any way to reset the USB subsystem/reload the drivers that I can try as a work around? It's annoying having to reboot to charge my phone. Nicholas
