From 834e2312e7a384877a876b0d34dffc3046c96bcb Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 13 Sep 2010 10:43:25 -0400 Subject: USB: teach "devices" file about Wireless and SuperSpeed USB The /sys/kernel/debug/usb/devices file doesn't know about Wireless or SuperSpeed USB. This patch (as1416b) teaches it, and updates the Documentation/usb/proc_sub_info.txt file accordingly.
