H A D | uhci-hcd.c | diff cec3a53c Fri Jan 08 09:18:20 MST 2010 Alan Stern <stern@rowland.harvard.edu> USB: EHCI & UHCI: fix race between root-hub suspend and port resume This patch (as1321) fixes a problem with EHCI and UHCI root-hub suspends: If the suspend occurs while a port is trying to resume, the resume doesn't finish and simply gets lost. When remote wakeup is enabled, this is undesirable behavior. The patch checks first to see if any port resumes are in progress, and if they are then it fails the root-hub suspend with -EBUSY.
