It's strange that Linux will not accept audio class 1 devices (at least not as a default). Everything that is simple and still about 90% of all USB audio devices offered are audio class 1 devices.

The Linux kernel is monophilic, every device driver lives in the kernel. They can be dynamically loaded as well. It really depends on the choices the person/group compiling the kernel chooses. Lots of dists are based on Ubuntu, which seems to compile most everything in. Ubuntu is based on Debian, so perhaps Debian compiles everything in. Examples are HPFS and JFS support. Ubuntu derivatives support them out of the box. Other Linuxes, not so much.
So really it depends on the distribution. The kernel supports both.

Not 100% sure on its accuracy since I deleted my last Linux partition a decade ago after using it since v0.1, but I have had numerous complaints about usba1 audio devices not working in Debian that work fine in Ubuntu (I ran a Linux audio site in the 90's, and still get emails 20 years later). I am personally more annoyed about Windows 10 support sine it means millions of headsets are no longer working.

DSD enabled devices mostly use an XMOS front end (Although ESS has recently released their own frontend for testing), while they mostly default to usba1, they should switch to usba2 if they get AudioClassRequests_2 according to my understanding of the XMOS docs

Also come to think of it, anything with class compliance and support for frequency rates above 96k is bound to be class 2 compatible.

Can anyone point me to a "audio standard 2.0" device ? The very cheap devices usually implement "audio standard 1.0" but I need "audio standard 2.0" in order to test. Hopefully, I can find something that is not overly expensive.

Here is how you can find out about what you have:
1) get lsusb.exe. This tool allows you to list the complete descriptor contents of a USB device
2) run "lsusb.exe". It will list all attached devices with their vendorid:productid. You will have to guess what is what by attaching and detaching USB devices.
3) run "lsusb.exe -v -d vendorid:productid where "vendorid" and "productid" are the numbers from step 2.Pipe the tool output into a file.
4) in that file, search for something like this:
      AudioControl Interface Descriptor:
        bLength                 9
        bDescriptorType        36
        bDescriptorSubtype      1 (HEADER)
        bcdADC               1.00
        wTotalLength           38
        bInCollection           1
        baInterfaceNr( 0)       1

If "bcdADC" says 1.00 then you have an audio standard 1.0 device. If it says 2.00, then you have an audio standard 2.0 device.

The problem is that if I search in Amazon or elsewhere, they never give that level of detail in their stupid product descriptions.

Anything that advertises Linux compatibility? The Linux kernel has not had usba1 compiled in as standard for at the least 6 years although some distributions like Ubuntu do supply kernels with usba1 enabled. As I am still on Firewire mostly I cannot help you as the only USB devices that I am certain of have usba2 are Micromega MyDAC and Arcam rPAC, both have switchable class compatibility but are relatively expensive, although the rPAC is frequently going cheap on eBay these days because it switches back to usba1 on every restart, which means incompatibility with modern Linux and Windows if you do not, or are not aware of how to switch it back.

I use RealVNC. I'm on iOS, but I think they have Android, too. Is running VNC on the main server a security risk?

Not if you configure it correctly, i.e. only one port open and a strong password.

Programming / Re: Liberty Basic for OS/2
« on: November 15, 2020, 10:08:26 pm »
Carl Gundel, the author of LB was on this site a year or two ago asking for help with a Warp setup so he could finish sorting out old bugs. You should also try True Basic, demo is on Hobbes, still available commercially although with limited or no support for USD 25, actually quite good in some respects.

BTW Liberty Basic is a tad slow, its interpreter was developed in Smalltalk, which is not the ideal environment for such.

Hardware / Re: AMD Ryzen 2nd generation processors
« on: October 26, 2020, 07:43:58 pm »

This board has real USB2, just not the actual connectors on the back plate

Connect a USB1/2 slot plate connectors or case connectors to the USB_3_4 or USB_5_6 headers on the motherboard, and you will have a working USB 2 slots that are hooked up to the AMD USB 2 implementation on the SOC, not the ASMedia USB 3.2 built into the B450. These are connectors 19 and 20 on the motherboard drawing, between the COM port header and the clear CMOS jumper.

Are you sure of that?  At the moment I have those headers connected to USB 2 ports on the case and a backplain strip and they require the XHCI USB 3 driver to work - I have not found a combination of USB 1.1 and 2 drivers that load and see them.

Disabled by default in the UEFI configuration I believe, it is a subfolder under the AMD CBS tab

P.S. These are useful to have connected under any OS, Realtek based USB 3 Wi-Fi sticks and a number of USB audio solutions for instance, are prone to dropouts under USB3.

The fact that the motherboard doesn't have any real USB 2 ports (those it does have are a subset of the USB 3 CPU/chipset) did make things a little 'sensitive' to start with - the trackball kept on locking up if I tried to click on something while waiting for something else to happen.

Internet / Re: The new browser / QT5
« on: September 25, 2020, 02:26:36 pm »
There's not many options besides the QT based browser. FF52 could still be ported and then the various forks such as PaleMoon could be ported. Really, now there is the Webkit browsers, Firefox and its forks.
Users of older PPC Mac hardware are truly blessed by Cameron Kaiser's work on TenFourFox. The Pale Moon/XUL project is also interesting as from it there has spawned independent forks for OS X Snow Leopard and even Windows XP!

I have an old PPC Mac and TFF is not exactly in great shape, as for Pale Moon it is buggy and the original author does not like forks, see: https://github.com/Feodor2/Mypal/releases

Apart from that Feodor2 has been doing a bang up job

It is the first time I hear about proxmox, I may be getting behind in the infrastructure market :)


It's a fork of OpenVZ (Linux only container solution, basically Ububuntu + limited virtualisation, it is not a true hypervisor) with bits of LXC transplanted onto it to give it a more generic OS support, as it stands support for anything that is not Linux is rudimentary.

It is supposed to work like Solaris Containers, but lacks in many respects.

General Discussion / Re: OS/2 on a Via C7 desktop?
« on: September 12, 2020, 02:49:40 pm »
Some of those older Wise Thin Clients are actually crippled terminal or Zero Client devices, sometimes in the BIOS, even is some cases will only allow Wise's own Linux version to run and nothing else. After the Dell takeover things got better and for the last decade Dell and Wise branded TC's have been just re-branded Clientron devices (Which in fairness have some BIOS limitations of their own).

For TC's of that vintage I have had much better results using HP's, TECO's and in particular IGEL hardware to run OS/2 derivatives on.

« on: September 10, 2020, 03:32:35 am »
I recently rescued a MicroATX motherboard with a Via C7 CPU.  it is a 2005 release, and would have winxp normallly,  The board has IDE, SATA, and USB.  Does anyone have any idea if I could get OS/2 Warp running on this hardware?
I run a couple of C7 systems for testing mostly, SNAP handles the graphics of all VIA/S3 graphics released up to VX900 (Ca 2009, a couple of them need to run in SNAP "compatibility mode") and the Via chipsets and ethernet controllers of that era were well supported by DANIS etc since they were the same as used with Intel boards with Via chipsets, the C3 to C7 family uses a Intel 370 bus basically.

Are those files on the ArcaOS install disk?  If so, how can I extract just the java sdk files so that I can build the jar?  Can that be done without installing the update?
