From f0597a416dc44e3afe25090e9af9d42bad62547d Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 17 Oct 2005 17:15:46 +0200 Subject: [ALSA] usb-audio: don't call usb_reset_configuration() when probing Modules: USB generic driver Remove the usb_reset_configuration() call from the probe callback because it isn't needed and it may interfere with other drivers already loaded for the device.
