The spec says: Suspend: (PORT_SUSPEND) This field indicates whether or not the device on this port is suspended. Setting this field causes the device to suspend by not propagating bus traffic downstream. This field may be reset by a request or by resume signaling from the device attached to the port. I can't find any specific statement like "the PORT_SUSPEND field is reset automatically on remote wakeup", but without this patch, the only way to reset it is via the ClearPortFeature request so the ".. or by resume signaling from the device" clause is clearly not implemented on the remote wakeup path. The default xhci Windows driver does not issue the ClearPortFeature request and suspended devices attached to a hub don't properly get out of the suspended state. Interestingly, the default uhci Windows driver *does* issue the ClearPortFeature request and does not exhibit this problem.
