I know what you want but a simple PC => USB => DEV => ADAT1 => ADAT2 is not possible.

You could use a MOTU LP32 + 3 ADA8200 to do what you want

I could do the same with my 16A, which has its own analog I/Os and 2 ADAT I/Os for 2 Behringers.

You can use a device with USB and 2 ADAT I/Os as dev1 + 2x Behringer ADA8200 as dev2/dev3

All iConnectivity devices (audio and midi) are controlled by MIDI sysex messages. Their iConfig configuration software can be used in Wine. I'm using it for my MIO10. On their website they even provide a manual describing the sysex protocol used, so someone with too much spare time could write a nat...

Connect the Ultralite to Ethernet and set the samplerate in the Web UI.

You can do this statically at boot time with the isolcpus= boot parameter or dynamically using cpusets

Of course the output of lsusb -v doesn't change.

With the recompiled driver loaded you should see the GR-55 as audio device.

.. and this thread should be continued in the "Computer Related Hardware" section.

For a start, add this to the quirks-table.h: { /* Roland GR-55 */ USB_DEVICE(0x0582, 0x0127), .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { .vendor_name = "Roland", .product_name = "GR-55", .ifnum = QUIRK_ANY_INTERFACE, .type = QUIRK_COMPOSITE, .data =...

Getting the audio part of a Roland/Boss USB device working is usually a matter of adding a quirk and recompiling the snd-usb-audio driver.

What is the output of "sudo lsusb -v" for this device ?

The TC Konnekt 48 is supported by ALSA since kernel 4.18

For the midisport you need to have the package "midisport-firmware" installed.

The 3.0 card has its own host controller and interrupt. So if you connect your audio interface to a USB port of the 3.0 card and all other devices to your builtin USB ports, the soundcard has its own interrupt.

The short answer: Yes, you need usb 3.0 card. The long answer: You are using an xhci host controller. While this host controller allows up to 8 MSI interrupts, the linux host controller driver allocates only 1. The usb 2.0 root hub you see is integrated in the xhci host controller, so it is also usi...

i meant the first of the available AVB streams.

Then it looks as if ALSA does not use implicit feedback for synchronization of input and output for this device. Changing this requires a kernel patch.

Use 48 or 96 samples with 3 buffers. And forget about the reported latencies on W10, except if they were measured with the RTL utility from oblique audio.
