Hello Brian,
I can answer the second part of your message at least. The device shows
up in device manager as "USB Audio Device" in device manager because it
enumerates through the class identifiers in the wdma_usb.inf file. Only
devices which are explicitly called out by this file will show up
otherwise.
As to why the device does not show the proper controls, I cannot be
certain without the device in hand. Perhaps if you sent me a listing of
your descriptors I could better understand.
Thanks,

Subject: [wdmaudiodev] USB Audio class device
Hi,
I've developed a usb audio class device, it's a microphone. An IT, a
feature
unit and an OT, it works fine in Windows XP, i mean i can record audio
in
the Sound Recorder. The detail is, that i can't find to make windows
detect
the feature unit, because when y select my device in Control Pane->
Sound
the Volume button is disabled. I've have programmed the device to answer
to
GET and SET CUR, MAX, MIN and RES and tested them with Jungo's WinDriver
Wizard. So, wich could be the issue?
Another thing is that when i plug my device, and the balloon pops up, it
says: "Microphone" (My product name) then USB Composite Device (As it's
get
registered in the Device manager list under USB controllers, then it
detect
the "Interface 0" and then USB Class Audio. So far it's nice, but why
does
the interface get listed in the Device Manager under Sound, video and
game
controller as "USB Class Audio" rather than "Interface 0". Notice that
in
Control Pane-> Sound in the dropdown box i have "Interface 0" as the
device
name.
Thanks a lot
Afro.
