From 8adb4786789c25007f39b4d00dd03cc83bdcb896 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 4 May 2007 11:53:30 -0400 Subject: [PATCH] USB: don't unsuspend for a new connection This patch (as889) prevents the hub driver from trying to resume a port when there is a new connection. For one thing, the resume is not needed -- the upcoming port reset will clear the suspend feature automatically. For another, on some systems the resume fails and causes problems.
