It appears that your UGREEN adapter (Model 30521)  (C-Media CM6533 chipset) 0d8c:0024 works with synchronous endpoints.
That is if the lsusb report that I found on the internet is the proper one for your device. You might want to run "lsusb -d 0d8c:0024 -v" to verify that.
Perhaps in some way that is causing the problem. Most UAC1 compliant adapters use adaptive endpoints.

From Glossary D

a dead or abandoned status for a trademark application means that specific application is no longer under prosecution within the USPTO, and would not be used as a bar against your filing. It does not necessarily mean that there are not other marks that the trademark examining attorney would cite. It is also possible to revive an abandoned application (for example, if the USPTO declared the application abandoned for failure of the applicant to respond to an Office action, but the applicant later proved that a response was sent and the USPTO simply failed to match it with the file in a timely manner, then the case could be revived). Also, regardless of the status of an application within the USPTO, the owner may still claim common law rights, i.e, the mark may still be in use in commerce.

Now I hope that someone with experience call tell me if the Audio USB input is supported or not.
Yes. Both playback and recording are supported with the Lars Erdmann USB 10.234 audio drivers.

Any suggestion for audio recording software. I'm using the one includes on ArcaOS 5.0.5 (Digital Audio), but for the moment I was not able to get input audio from the USB device. (But it records from the non-USB mic input jack)


Hi Martin,

Perhaps DRECORD or DTAPE or even my own Audio Recorder to record up to 32 bit stereo at 384kHz. ?

Hi Lars,

Hi Wim,

if you are talking about the Multimedia Setup Object Extension that I have written:
I have no clue if ArcaOS also delivers that extension. Can you see if the ArcaOS package (USBAUD2.WPI) contains the DEFDEV.DLL file (the DLL that implements the Multimedia Setup Object Extension) ? The WPI command line tool (WIC.EXE) should be able to list the WPI content.

Yes, I was talking about that Multimedia Setup Object Extension written by you (part of the audio part of
But I have no clue either whether or not ArcaOS delivers that extension. I have no access to that USBAUD2.WPI either.

I searched under ArcaOS 5.0.5 DVD, I found aswitch files I copied under MMOS2 and run aswitch.
Plugged an usb dac to it but didn't work and since then, no more audio under ArcaOS !
"removed the dac, no speaker audio, removed aswitch files, no speaker audio...."
How to reverse and get audio back using auniaud drivers ?
I have ArcaOS 5.0 installed. I never used ASWITCH, nor <DVD>:\CID\SERVER\ARCAPKG\USBAUD2.WPI. What I would do:

Go to System Setup, Multimedia Setup. On the System, Default WAVE Device Selection page, Select the uniaud device and press Enter.

I used the Conceptronic CSOUNDU to develop and test Audio Class 1.0 recording support.

I used the Behringer UMC204HD to develop and test Audio Class 2.0 recording support.

Hi Remy,

To record zmovie.avi I used webcam.exe /a/n and the following line:

ffmpeg -async 1 -framerate 25 -itsoffset 2.0 -i \PIPE\Webcam\Video -i \PIPE\Webcam\Audio -c:v copy -c:a copy -map 0:0 -map 1:0 zmovie.avi

And it works very well. The following line produces compressed output (10 times reduction in filesize):

ffmpeg -async 1 -framerate 25 -itsoffset 2.0 -i \PIPE\Webcam\Video -i \PIPE\Webcam\Audio -map 0:0 -map 1:0 zmovie.avi

And works very well too. But I do prefer the uncompressed movie.

There is no delay in the recorded audio and it stays in sync.

Best regards,

Hi Remy,

I just did a few test (audio delay seems to be much better but not enough time to be sure "larsen")
tried with c270: default or /a3 provides no audio, I have to set /a1 to get some audio
On my DELL Latitude E6500 laptop /a1 is the builtin audio adapter and /a2 is the Conceptronic CSOUNDU and /a3 is the Behringer UMC204HD.
The Behringer UMC204HD is setup as the default device and thus on my system /a0 is that adapter too.
See USB Audio Adapters on my website. ;) Now you know where wmaudio is coming from.

May it possible to add a volume level flag to wmaudio ?  /vNNN or something like that (volume level adjustable from 0 to 100 ? like ffplay has)
Done. I added the /vN parameter and I changed the default of the /aN parameter. See wmaudio.txt for more information.

Hi Remy,

Thank you for your explanations and modifications. works well.

Only audio does not work for me because I have ffmpeg 2.8.6-2 installed which does not support -volume 30 nor -nodisp.
4/ "Without -volume 30 and without -nodisp audio works"
     It must work but I think your system audio level is set very low (ref for 100) and when 30 is used, the audio is then very very low may be like no sound (I'll added an option to use default volume at 100 or to reduce it to 50). -nodisp has no impact here and prevent video simulation process for audio stream.
That is not the case. It does not work because I am using ffmpeg 2.8.6-2 which rejects -volume 30 and -nodisp.

I have updated webcam.exe because:
A. It now recognizes webcams better while scanning descriptors.
B. It may obtain 22050/44100 Hz. audio streams from logitech webcams.
Note: Audio capabilities are still hardcoded i.e. descriptors not scanned.

May be wmaudio could provide a syncronized audio with the ffplay video output !
I added wmaudio.exe - Webcam Monitor Audio for OS/2 - first beta version.
Not really synchronized but perhaps more appropriate.
Best regards,

Hi Remy,

Test results with

1. I saw the "Missing Requirements" popup several times.
    Each time only once just after booting op the system.
    But not always. Too short timeout perhaps?

2. Now all yuyv formats are found for the builtin webcam.
    1600x1200 and 1280x1024 formats only show with the [] button.
    Perhaps because my laptop screen size is 1440x900 pixels?

3. Cam-Intf range is 1:9 but logitech webcams have 1:11 range.
    There could be webcams out there with even a larger range.

4. Audio does not work with my ffmpeg 2.8.6-2 installation.
    Without -volume 30 and without -nodisp audio works.
    And without -sync ext audio works somewhat better.

5. When I set Defaults Audio to 22050HZ then 48000 Hz is used.
    When I set Defaults Audio to 44100HZ then 48000 Hz is used.
    The c250/c270 webcams support 16000/24000/32000/48000 Hz.
    I could make these deliver 22050 Hz and 44100 Hz too.
    At least the list must include 24000 Hz and 32000 Hz.

Hi Rémy,

At last some test results working with

1. Buttons "Cam is off" and "Cam is on" do their work.
2. Video is shown when using the show and [] buttons.
3. Query vSize list c250 webcam never finds 640x400 video formats.
4. Query vSize list e6500 webcam does not find yuyv 640x480,1024x768,1280x1024 formats.
5. Query vSize list e6500 webcam finds yuyv 1200x1600 format but size button does not show it.[] button shows it.
6. Query vSize list e6500 webcam correctly finds no mjpg formats. But see point 7.
7. Using Defaults Max Vsize after point 6. shows strange VMMXxVHMx default format.

This WCC version works much better than the previous ones.
Audio has not yet been tested but I will try that tomorrow.

Documentation needs brushing up: better structure and better spelling.
Pictures and text need to match what the program does and what it shows.
But you know that already. Not easy to do. To be done...

Hi Rémy,

Thank you for the lsusb report of the logitech QuickCam Pro 9000.
Now I can see some differences with the logitech QuickCam Pro for notebooks.
In particular wMaxPacketSize being 1x36 bytes versus 1x68 bytes (c250/c270 too).
However my program has hardcoded 1x36 bytes for 16000hz so it should work.
Please try webcam /a/n with your logitech c270 to see if that fails too.

Right now I am working on two companion webcam monitor programs:

wmaudio.exe - Webcam Monitor Audio for OS/2 (ArcaOS/eComStation)
wmvideo.exe - Webcam Monitor Video for OS/2 (ArcaOS/eComstation)

wmaudio.exe /aN plays audio thru AmpMix0N so on any audio adapter.
Input is \PIPE\Webcam\Audio. It plays with minimal delay.

wmvideo.exe is a pm program that shows video on your desktop.
Input is \PiPE\Webcam\Video. It shows with minimal delay.

The purpose is to monitor audio and video while recording with ffmpeg.
The question comes up how do you want to connect the Webcam Server?
Obviously there is one connection missing for audio. What to do?
Did you already try to record audio and video at the same time?

Best regards,

Hi Rémy,

Tried webcam /a16000, no audio from 9000 pro
No audio - does that mean that the audio window titled \PIPE\Webcam\Audio does not appear?
Or does that window appear but no audio can be heard i.e. dead silent (like volume is zero)
Is there any error shown? Like [00004000] obtain audio error? 
When using webcam /a/n do you have video but still not sound?

Same results for USBRES which shows now the logitech QuickCam pro 9000 (but not the C270!).
This allows me to get needed information for you :D
Thanks. It confirms that the logitech Quickcam Pro only supports 16000 Hz. audio.
Apart from idProduct the Quickcam Pro for notebooks has the same usb descriptors.

I have attached lsusb-046d0991.txt that I found on the internet.

Hi Rémy,

Sorry, I supposed you where on a higher AN modification level with USB3 support.
No need to apologize. We never know what is exactly going on somewhere sometime. 

While developing Webcam Server for OS/2 (ArcaOS/eComStation) I used the 12.05 drivers.
That was cumbersome because I ran into a lot of traps, reboots, lost sources and so on.
It could be my poor coding or perhaps it was caused by something else. So what to do?
So I decided to follow the safest path I could think of: use Lars' 10.234 drivers.

Right but 16 bits drivers are old style and not compatible with new HW (e.g. USB3)
It is better to work with new ones.
Requires me to install ArcaOS 5.0.5 on my Dell Latitude e6500. No space. No time.
Therefore I am grateful that you, Rémy, work with ArcaOS 5.0.5 and the latest usb drivers.
And what is more, you take your time and effort to file problem reports in ArcaOS mantis.

I left my c270 plugged and added my webcam 9000 pro on an other USB2 port.
HWMANAGER show the same information and only C270 while HWEXPLORER (using latest Jully usb.ids shows the 9000pro webcam) which seems to be correct due when I start webcam, the 9000 pro goes active and not the c270....
See the HWEXPLORER output. 
The way you shwowed the output of Hardware Explorer is not convincing.
The Hardware Explorer must actually be running to get updated information.
And even then you need to redo showing that output using the way you did.
You better look at the life updating (tree) view of the Hardware Explorer.

May be I have to backlevel my USB driver to 12.5 to get some information again...   (I will try)
I think it is better to just report the problem that lsusb -v is not working with 12.06 drivers.
To get audio working for the logitech quickcam pro 9000 has to wait till that has been solved.
It is my understanding that the logitech quickcam pro for notebooks only supports 16000 Hz.
Perhaps the logitech quickcam pro 9000 only supports 16000 Hz too. Try webcam /a16000.
Best regards,

Hi Rémy,

I see that you have the same issue that I have when using USB 12.6 (as I write it previously)
Not really true. I have no problem using lsusb but then I am using Lars' 10.234 usb driver set.

From your report, no webcam found !  (like me, no webcam found and I think this is related to know USBXHCD limitation)
Not really true. The logitech c250 was not connected at that time. See below for the list when connected.

Code: [Select]
Bus 001 Device 001: ID 1397:0508 BEHRINGER International GmbH
Bus 001 Device 002: ID 0c45:63f0 Microdia
Bus 001 Device 003: ID 0a5c:5800 Broadcom Corp. BCM5880 Secure Applications Processor
Bus 001 Device 004: ID 056a:030e Wacom Co., Ltd CTL-480 [Intuos Pen (S)]
Bus 001 Device 005: ID 046d:0804 Logitech, Inc. Webcam C250
The Microdia with ID 0c45:63f0 is the dell latitude e6500 builtin webcam.

Webcam works but lsusb no more provides any report...
Do you have the same issue in this case and are you able to get usb webcam lsusb results under your AN 5.0.5 ?
note: I asked the question to the support if this needs a new ticket.
No. I don't have usbxhcd.sys installed. and I have only usb 2.0 ports. I am using AN 5.0 i.e. the first release.
You could try and use USB Device Monitor Version 0.9.7 (usbres.exe) to see if the webcam is listed.
Seems to me that a new ticket is needed.
