hallo all,
i have Logitech QuickCam E3500 ... with little issue.
Setting capture volume to more then 94% will mute this device... no 
capture will be possible. This device has same issue with windows vista. 
So best way to handle it, is usbquirks.h , but i do not know any way to 
set max level.


amixer report this device like:
=========================================
Simple mixer control 'Mic',0
   Capabilities: cvolume cvolume-joined cswitch cswitch-joined
   Capture channels: Mono
   Limits: Capture 0 - 3072
   Mono: Capture 2950 [96%] [23.00dB] [on]
==========================================

here is alsa-info.sh output:
http://www.alsa-project.org/db/?f=ecd6ea8c7a37c7aa036c88026885f324ef2ab067

As you can see it report it's limits 0-3072 .. but real limit is 0-2943.

Please if any one has some idea, meail me.

Regards,
     Alexey
