Title: USBDRV 10.225 - full support for USB audio
Post by: Lars on November 14, 2018, 07:27:49 am
The new package now contains drivers for USB audio standard 1.0 and also audio standard 2.0 (has nothing to do with USB 1.x vs. USB 2.0).
That should cover all current sound devices. The supported bit depths and sample rates are what is in use today, more details in the contained "readusb.txt" file.
Really, only playback has been tested, I am not sure in how far or to what extent recording will work.

If you need sound and if UNIAUD does not work for you then you might consider buying a set of USB speakers or a USB audio stick for plugging in earphones instead.

Thank you very much Lars.

Please, if somebody wants to report a USB Audio device working please post it or let me know. Give me the brand, model, hardwareID and any description you want to add, so I can include the device on the OS2World wiki (https://www.os2world.com/wiki/index.php/Audio_Cards#USB).

Regards

Hi Martin,

TOPPING D10 USB DAC 32bit/348khz DSD 256 XMOS U208 ES1918K2M works with OS/2 (ArcaOS, eComStation)

I bought this adapter specifically to develop and test USB Audio Class 2.0 support with OS/2 (ArcaOS, eComStation).
It works very well with the latest (10.225) Lars Erdmann USB driver set.

Martin, just a hint: there are audio standard 1.0 and standard 2.0 devices. That is relevant as the first needs the USBAUDIO.SYS driver and the second needs the USBAUD2.SYS driver.
You can distinguish these 2 standards by looking at the device descriptor info: if field "bcdADC" says "1.00" then it is audio standard 1.0 if it says "2.00" then it is audio standard 2.0.
That said, all the USB audio devices that you listing are audio standard 1.0 except for the "TOPPING" that Wim has been using which is audio standard 2.0.

Have an Sabrent AU-MMSA (https://www.amazon.com/Sabrent-External-Adapter-Windows-AU-MMSA/dp/B00IRVQ0F8 (https://www.amazon.com/Sabrent-External-Adapter-Windows-AU-MMSA/dp/B00IRVQ0F8)) since some months; works great and robust. No problem or traps so far.

Lars/Wim Great work and many thanks

Thanks Wim, Lars, RBri.

Here I had tried to document the device: https://www.os2world.com/wiki/index.php/Audio_Cards#USB (https://www.os2world.com/wiki/index.php/Audio_Cards#USB)
I also tried to include Lar's hint since it is very important.

RBRi, can it be possible to post the "USB Device Hardware Report" of that device to include it also on the wiki?

Really, only playback has been tested, I am not sure in how far or to what extent recording will work.

Since june 2019 I have been busy on getting recording working. I have put a beta test Audio Recorder and Replayer] (http://home.hccnet.nl/w.m.brul/recorder/index.html) and beta test audio 13.227 drivers] (http://home.hccnet.nl/w.m.brul/usbaudio/index.html) on my website. With this you may record and playback hires PCM audio streams. I made the Audio Recorder and Replayer  open source. The Lars Erdmann 10.227 drivers are prerequisite. I have tested this out with the behringer u-phoria umc204hd device and I can now properly record 32-bit PCM stereo at 44100, 48000, 88200, 96000, 176400, 192000 Hz with that device. These are the frequencies it supports with 24-bit resolution.

Hi Lars

Thanks for the new release.

Just a little thing, since yesterday a new directory was created at hobbes. "/pub/os2/system/drivers/usb" I think you should put you new releases there on the future.

I installed the listed OS2 USB components to the OS2 sub directories. Rebooted and the mouse no longer worked.  After rebooting several times without success of the mouse working, I booted to another of my ArcaOS partitions and copied the original OS2\boot USB drivers over the usbdrv228 USB drivers and rebooted to that partition and I had a working mouse again.

What version of USB drivers did you copy over? If it was version 12.1, from the new ArcaOS, you need to change the order of USBD.SYS in CONFIG.SYS. Installing version 12.1, or up, will correct the driver order. Installing earlier versions will not correct the driver order, if it is not correct for the version being installed.

SAMPLE for older versions:
Code: [Select]
BASEDEV=USBOHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBD.SYS
BASEDEV=USBHID.SYS
...

SAMPLE for 12.1, and up:
Code: [Select]
BASEDEV=USBD.SYS
BASEDEV=USBOHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBHID.SYS
...

Thanks Doug.  That was the problem.  I had copied the new drivers to the new ArcaOS 5.04 partition which resulted in the mouse not working.  Rearranging the BASEDEV drivers to the above order solved the problem.  Was there a reason why the USBD.sys driver order changed in the config.sys on Version 5.04?  Why would the order of the usb drivers listed matter.?

Seems that the order was changed to support USB3.
Lars should probably add something about the ordering to his readme, or perhaps he already did
Title: Re: USBDRV 10.225 - full support for USB audio
Post by: Lars on July 29, 2019, 09:27:03 am
sorry, but I don't understand.
If you are using the 12.1 driver stack then you do not use my USB drivers I suppose.
And if you use my USB drivers there is no need to change the config.sys USBD.SYS ordering (but I think you can do so without any negative effect but I will need to try out).
As far as USBAUDIO.SYS and USBAUD2.SYS and potentially USBMSD.ADD goes, there is no need to change anything in config.sys. They are in no way affected by the USBD.SYS ordering in config.sys.
Title: Re: USBDRV 10.225 - full support for USB audio
Post by: David Graser on July 29, 2019, 09:52:12 am
Just retested with Lars latest USB drivers installed again.

ArcaOS 5.04.  Moved the BASEDEV=USBD.SYS before the other basedev drivers as the way 5.04 does.

BASEDEV=USBD.SYS
BASEDEV=USBOHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBHID.SYS

Rebooted and the mouse does not work.  Note: the USB mouse did work with the USB drivers installed with ArcaOS 5.04 when using the above ordered config.sys.

Switched BASEDEV=USBD.SYS back to the order done in earlier versions of ArcaOS.

BASEDEV=USBOHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBD.SYS
BASEDEV=USBHID.SYS

rebooted and the mouse works with Lars drivers.

If the order was changed for USB3 and we don't have USB3 yet why change things when it can cause problems?
Title: Re: USBDRV 10.225 - full support for USB audio
Post by: Lars on July 29, 2019, 02:54:01 pm
Currently USBxHCD.SYS HC drivers try to register with USBD.SYS already on INIT. That will only succeed if USBD.SYS loads BEFORE these drivers (if USBD.SYS is first in config.sys). Therefore USBxHCD.SYS will try to register with USBD.SYS also on INIT_COMPLETE if the registration failed on INIT. That covers the case that USBD.SYS loads AFTER these drivers because INIT_COMPLETE will be called once ALL drivers have loaded (gone through INIT).
Obviously, the system does not seem to like it if the HC drivers already register on INIT. I will try and remove the registration already on INIT. Then, the HC drivers will register with USBD.SYS only if ALL drivers (regardless of config.sys ordering) have already loaded which would make the load ordering in config.sys irrelevant.
The code comments implied that all that was relevant if you boot from a USB floppy drive / CD-ROM. I just take it for granted that my drivers would then possibly no longer allow to boot from USB.

If the order was changed for USB3 and we don't have USB3 yet why change things when it can cause problems?

Because USB 3 does exist, and USB 12.1 is designed to have USB 3. It just doesn't have USBXHCD.SYS included, yet.

USBXHCD.SYS is the USB 3 driver, so it is not a good idea to refer to USBxHCD.SYS as meaning USBUHCD.SYS, USBOHCD.SYS and/or USBEHCD.SYS any more. Perhaps use USB?HCD.SYS, which would also include USBXHCD.SYS.

Because USB 3 does exist, and USB 12.1 is designed to have USB 3. It just doesn't have USBXHCD.SYS included, yet.

It does exist for "some of us", just as it is for about more than 3 Years now.

To clearify what "it does exist" means without speaking in miracles is:

(My question to ArcaNoae a few weeks ago got - regarding USB3 - the following answer sent by the ArcaNoae Sales Team):

The USB 3.0 stack is basicaly ready and on some systems it does work. However on *some* Intel chipsets the USBX.SYS host controller driver does not work yet. This is why the USB 3.0 driver has not yet been released.  David Azarewicz is working on the issue to try and resolve this.


@Lars Erdmann: it is a pitty, that your work (and possibly the same with the work of Wim Brul) may not be able to be used with the "closed Source USB 3 Driver" from ArcaNoae, once it does "really exist"

However on *some* Intel chipsets the USBX.SYS host controller driver does not work yet

The big question is, does that mean it works on all AMD chipsets or have they been forgotten? - enquiring minds would like to know the answer to that question.

I have tested the USBXHCD.SYS driver on a few machines, with "interesting" results (completely unscientific):

Lenovo ThinkPad L530, with Intel USB 3 adapter. The driver loads, but it doesn't recognize when a USB device is attached. That may have something to do with the internal USB HUB since one of the USB 2 ports doesn't work either, when the USB 3 driver is loaded.

Lenovo ThinkPad T510, with a StarTech ExpressCard USB 3 adapter (Renesas chipset, apparently). I can read from a USB 3 stick, but writing has problems.

Lenovo ThinkPad L530, with the StarTech ExpressCard. Won't even POST. Obviously some sort of conflict with the internal USB 3 adapter (nothing, at all, to do with any operating system).

IBM ThinkPad T43, with the StarTech ExpressCard. A quick test shows that it works as expected. It seems to be not much faster than USB 2, but that is likely a limitation of the machine speed. I have not stress tested this one, yet.

Asus M3A78-EM motherboard, with PCIe USB 3 adapter (Fresco Logic). The driver loads, but nothing happens when I plug in a USB device.

I have not, yet, tried my Asus A88XM-A machine. It has an AMD adapter, which seems to use the Fresco Logic driver, in windows.

So, three machines (ThinkPads), using the exact same ExpressCard adapter, and USB stick, have different indications. One of them actually works.

This sort of thing has got to drive programmers up the wall.

The big question is, does that mean it works on all AMD chipsets or have they been forgotten?

AMD motherboards may use different chipsets, it depends on which chipset is cheapest when the board is built. My Asus A88XM-A calls it an AMD device, but windows uses the Fresco Logic driver. In theory, ALL USB 3 adapters, and devices, are supposed to conform to the same set of rules. It appears that manufacturers are still ignoring the rules, as they always did with earlier versions of USB (including Intel, and they, apparently, wrote the rules).

Not that I know about, but that doesn't do us much good. A few thousand programmers seem to have managed to incorporate USB 3 support into the Linux kernel. That is not portable to OS/2, especially when one programmer is trying to do it.

In fact the Linux "guys" had full support from some Intel lady which eventually implemented (or led implementation of) the USB 3 driver for Linux.
Implementing an USB host controller driver is trial and error.

Just retested with Lars latest USB drivers installed again.

ArcaOS 5.04.  Moved the BASEDEV=USBD.SYS before the other basedev drivers as the way 5.04 does.

BASEDEV=USBD.SYS
BASEDEV=USBOHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBHID.SYS

Rebooted and the mouse does not work.  Note: the USB mouse did work with the USB drivers installed with ArcaOS 5.04 when using the above ordered config.sys.

Switched BASEDEV=USBD.SYS back to the order done in earlier versions of ArcaOS.

BASEDEV=USBOHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBD.SYS
BASEDEV=USBHID.SYS

rebooted and the mouse works with Lars drivers.

If you can get me a private email address, I can send you updated USB?HCD.SYS test drivers that no longer rely on a specific config.sys ordering regarding USBD.SYS. You'll never have to touch your config.sys again :-)
It works here, once I know that it works for you I can release a new set of drivers.

Ok, I just realized that I also need to update USBMSD.ADD and USBD.SYS. I will send the modified set as soon as I have tested all the changes.
