incorrect determination of the USB-sound card

[Sohin Vyacheslaw <in.soho@yandex.ua>]

Hi,


when an external USB sound card inserted in the logfile the following 
messages:
Oct 28 13:01:34 sldas kernel: [ 3036.571158] usb 2-1.2.1: new full-speed

Oct 28 13:01:35 sldas mtp-probe: bus: 2, device: 9 was not an MTP device

  idVendor and idProduct -> correct: C-Media
but CM109 USB driver is for voip phones:

$  modinfo cm109
filename: 
/lib/modules/3.2.0-4-686-pae/kernel/drivers/input/misc/cm109.ko
license:        GPL
description:    CM109 phone driver
author:         Alfred E. Heggestad
alias:          usb:v0D8Cp000Ed*dc*dsc*dp*ic03isc00ip00*
depends:        usbcore
intree:         Y
vermagic:       3.2.0-4-686-pae SMP mod_unload modversions 686
parm:           phone:Phone name {kip1000, gtalk, usbph01, atcom} (charp)

I've tried to use each parameter (kip1000, gtalk, usbph01, atcom) and 
try on a different linux distros with different kernels (also compiled 
kernel) - the result is the same card plays audio, but some functions 
don't work properly: increase, decrease volume...

In Windows 7 operating system all functions of this sound card correct...

what's the right driver can be used for this card in Linux?


p.s.  after enabling CONFIG_USB_DEBUG and rebuild the kernel in logfile 
when connecting card:
