if you have run winetest-latest.exe in windows

set WINETEST_INTERACTIVE=1
winmm_test.exe mixer

you should notice that the output of your usb mic should be similar to the
following

mixer.c:759:   2: "USB Mic" 0.5 (65535:65535) destinations=1

mixer.c:830:     0: "Capture" (Capture) Destination=0 Source=-1

mixer.c:833:         LineID=ffff0000 Channels=1 Connections=1 Controls=2

mixer.c:837:         State=0x00000001(MIXERLINE_LINEF_ACTIVE)

mixer.c:839:         ComponentType=MIXERLINE_COMPONENTTYPE_DST_WAVEIN

mixer.c:841:         Type=MIXERLINE_TARGETTYPE_WAVEIN

mixer.c:843:         Device=3 (USB Mic) 0.5 (65535:65535)

mixer.c:875:       0: "Microphone" (Microphone) Destination=0 Source=0

mixer.c:878:           LineID=00000000 Channels=1 Connections=0 Controls=0

mixer.c:882:          
State=0x80000001(MIXERLINE_LINEF_ACTIVE|MIXERLINE_LINEF_SOURCE)

mixer.c:884:           ComponentType=MIXERLINE_COMPONENTTYPE_SRC_MICROPHONE

mixer.c:886:           Type=MIXERLINE_TARGETTYPE_WAVEIN

mixer.c:888:           Device=3 (USB Mic) 0.5 (65535:65535)

perform the same test on wine 1.3.7

WINETEST_INTERACTIVE=1 ./wine dlls/winmm/tests/winmm_test.exe.so mixer

mixer.c:759:   2: "USB Device 0x????:0x????" 1.0 (170:85) destinations=1
fixme:mixer:getsrccntfromchan No src found for 0 (L"Mic")?
mixer.c:830:     0: "Mic" (Mic) Destination=0 Source=-1
mixer.c:833:         LineID=00000000 Channels=1 Connections=0 Controls=1
mixer.c:837:         State=0x00000001(MIXERLINE_LINEF_ACTIVE)
mixer.c:839:         ComponentType=MIXERLINE_COMPONENTTYPE_SRC_MICROPHONE
mixer.c:841:         Type=MIXERLINE_TARGETTYPE_WAVEIN
mixer.c:843:         Device=-1 (USB Device 0x46d:0x992) 1.0 (170:85)

This mean that those usb mic patches still break the wine compilance test

although it won't crash the game
