Re: Mackie ProFX10v3 problems

Nothing wrong at first glance. Do ProFX10v3 and ProFX6v3 share the same USB ID? I mean, could this lsusb output be actually from ProFX6v3? Or it was disconnected?

Code: Select all

[   68.234268] usb 3-6.1: Presonus Studio 1810c, device_setup: 0
[   68.234270] usb 3-6.1: (8out/14in @ 96kHz)

Interesting. Module parameter device_setup didn't apply for some reason. Is 1810c the only USB card connected?

dave@pmuddstudio:~$ sudo echo "options snd-usb-audio device_setup=1" > /etc/modprobe.d/alsa.conf

This should work:

Re: Presonus 1810c | Ubuntu | sample rates are missing

This device is somewhat non-standard: [1]. It supports different set of sampling frequencies per altsetting. IIUC from the patch, you need to pass device_setup parameter to the snd-usb-audio module. Something like this: echo "options snd-usb-audio device_setup=1" > /etc/modprobe.d/alsa.con...

Re: Motu M2 USB Interface on Linux

Does anyone else here experience the problem that the Motu M2 needs a power cycle after booting and especially rebooting? Different hardware revisions have different issues. I believe that all remaining problems with MOTU M Series cards should be fixes in the near future: patch for the 1st revision...

Thanks! That explains a lot.

I bet that it's a sound card. :) But I don't know how to find mapping between devices connected to xhci controller and their IRQs.

Re: How much RT optimization is still needed?

Also note that udev-rtirq (https://github.com/jhernberg/udev-rtirq) doesn't work correctly for xhci.

Re: How much RT optimization is still needed?

turbidh20 your method of finding IRQ doesn't work for xHCI controllers. These controllers use MSI/MSI-X interrupts and allocate dedicated interrupt for each connected device (at least my old uPD720202 do). 02:00.0 USB controller: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller (rev 02) (...

This is in line with Gen 2 devices: only interfaces with digital I/O work in asynchronous mode.
