From 1299cff9fa39811cd1b3f1731527b062425f0541 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Thu, 17 Jul 2014 15:40:57 -0400 Subject: [PATCH] USB: shutdown all URBs after controller death When a host controller dies, we don't need to wait for a driver to time out. We can shut down its URBs immediately. Without this change, we can end up waiting 30 seconds for a mass-storage transfer to time out.
