From fd865ea20e1c05d7e9b7d081632db5fa6ad32a3a Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Sat, 7 Apr 2007 23:11:47 -0500 Subject: pvrusb2: Gather USB bus address info and report it From: Mike Isely The V4L2 API requires a unique bus_info string returned as part of the v4l2_capability structure. These changes gather up the USB address information, from the underlying device, into a string and report that out through v4l2 and via sysfs (for completeness).
