From 14faf12f7df8404c3e8e54baad8d178c327a2f87 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Thu, 12 Mar 2009 11:08:51 -0400 Subject: [SCSI] Increase default timeout for INQUIRY This patch (as1224) changes the default timeout for INQUIRY commands from 3 seconds to 20 seconds, which is the value used by Windows for USB Mass-Storage devices. Some of these devices, like the Corsair Flash Voyager (see Bugzilla #12188) really do need a long timeout.
