From 17d900c4a1b50bc191b3ca58cbd78acc04a1c5b3 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 26 Sep 2011 21:15:27 +0200 Subject: ALSA: usb-audio: increase control transfer timeout There are certain devices that are reportedly so slow that they need more than 100 ms to handle control transfers. Therefore, increase the timeout in mixer(_quirks).c to 1000 ms. The timeout parameter of snd_usb_ctl_msg() is now constant, so we can drop it.
