Hardware / Re: USB Scanners and ArcaOS

Exactly. You need to install an additional RPM that is not listed as a prerequisite.
You need to install "sane-backends-drivers-scanners".
That will drop a bunch of DLLs into /usr/lib/sane, one DLL per conf file.
And if a scanner is a USB scanner, these DLLs will use usb100.dll which in turn uses USBCALLS.DLL to do their job.
So now I have installed "sane-drivers-scanners" and I have deleted scanimage.exe (size 4.817.128) from h:\tame.

Now scanning with the CanoScan LiDE 210 using Tame/2 on my ArcaOS system works with the latest drivers.

Thank you, Lars!

So what is the strategy / configuration options available to utilize the RPM SANE release in a TAME installation?

I haven't actually tried it yet but it seems like removing the previous SANE install from the TAME directory and literally having TAME issue the normal calls it normally would, which in this case would all come from the \usr\bin directory, should suffice?

It goes w/o saying that the appropriate changes in the various SANE SET...= options need to be made as well.

I guess that scanimage.exe (size 25.154) in \usr\bin works by dynamically loading scanner specific backends.
It seems to me that the "Sane from Netlabs RPM - sane-backends - 1.0.28-2" does not contain these.

Hi Wim,
I assume you are using an up to date version of USBCALLS.DLL and USBRESMG.SYS, correct?
That at least would confirm that we do not need to rework either one.
Yes Lars, that is correct. No rework required.

Hi Andreas,

Perhaps How I installed SANE and TAME for the first time on my ArcaOS system. I used a two step approach. helps you in getting your CanoScan LiDE 210 scanner working.

The sane-find-scanner.exe (size 81.044) works and shows:found USB scanner (vendor=0x04a9 [Canon], product=0x190a [CanoScan], chip=GL124) at libusb:001:005

Speaking about backends. The scanimage.exe that works (size 4.817.128) has the sane scanner specific backends linked in.

Today I tested the "HP Gaming Headset H320GS".

Audio output is working, and recording also work (tested with DTAPE), even that it records the audio too fast (I sound like a chipmunk).

When using DTAPE for recording you need to set the correct Record Type before you open a new file. You have to do this only once anytime that you plug in a different usb audio device.
For the HP_Gaming_Headset_H320GS you may use PCM, 44100 Hz and 48000 Hz, 16 bits, Mono, Line in. See here for more information...

I have a question about Wim's Audio Recorder. I noticed on the readme that you need to run it like "record /a1 /b16 /c1 /f44100" (it works fine that way with my laptop internal mic), but how an USB mic should be tested with "Audio Recorder"?

Go to the Multimedia Setup and select the USB Adapter Wave tab.
When it shows Waveaudio02 device then use the /a2 argument.

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.

Yes. Both playback and recording are supported with the Lars Erdmann USB 10.234 audio drivers.

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.
