Same behavior here, using Ubuntu mate 23.10 / 1.26.2 and google chrome (from chrome .deb, not chromium or a snap or flatpak). Kernel is Linux 6.5.0-21-generic x86_64
The circuit tracks has firmware 1.15 (latest, from dec 2022), and the following script is run before hand as root to set the midi buffers (this is required with firmwares > 1.02 with the circuit tracks as newer firmwares use bigger chunks to speed up transmissions) #! /bin/bash echo "must be run as root" echo -n "current alsa midi OUT buffer size " cat /sys/module/snd_seq_midi/parameters/output_buffer_size echo 'setting alsa midi OUT buffer to 65535' echo "65536" > /sys/module/snd_seq_midi/parameters/output_buffer_size echo -n "current alsa midi IN buffer size " cat /sys/module/snd_seq_midi/parameters/input_buffer_size echo 'setting alsa midi IN buffer to 65535' echo "65536" > /sys/module/snd_seq_midi/parameters/input_buffer_size echo -n "new alsa midi IN buffer size" cat /sys/module/snd_seq_midi/parameters/input_buffer_size echo -n "new alsa midi OUT buffer size" cat /sys/module/snd_seq_midi/parameters/output_buffer_size Using Chrome, which worked before upgrading to 23.10, the novation components website attempts to connect ( webmidi is enabled/allowed in Chrome for this device), then times out. ( When starting Components in Firefox, the device doesn't show at all, but this is not new and din't work before upgrading to 23.10 either. ) I can connect to the device using components in chrome browser on an android device, so the circuit tracks and usb cable used are working as expected. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2043299 Title: Linux 6.5 breaks Novation Components web MIDI application Status in linux package in Ubuntu: Confirmed Bug description: Ubuntu version: 23.10 Kernel version: 6.5.0-10 Steps to recreate: 1.
