From: Pete Zaitcev Date: Tue, 19 Sep 2006 05:49:02 +0000 (-0700) Subject: USB: Dealias -110 code (more complete) X-Git-Tag: v2.6.19-rc1~899^2~6 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=38e2bfc94e95dd6005fdaf40dfec0157396741da;p=linux-2.6-omap-h63xx.git USB: Dealias -110 code (more complete) The purpose of this patch is to split off the case when a device does not reply on the lower level (which is reported by HC hardware), and a case when the device accepted the request, but does not reply at upper level. This redefinition allows to diagnose issues easier, without asking the user if the -110 happened "immediately". The usbmon splits such cases already thanks to its timestamp, but it's not always available. I adjusted all drivers which I found affected (by searching for "urb"). Out of tree drivers may suffer a little bit, but I do not expect much breakage. At worst they may print a few messages.
