Hello. Just put my hands on one Motu Ultralite AVB Work out of the box - Debian/Gnu 8.7 - with Jackd / Qjackctl (with an .asoundrc, not sure usefull to record, but needed to play audio from the browser with html5 videos online) Plugged in USB. Plugged with RJ45 cable to a hub, total access to the internal software with firefox on the IP address assigned to the card - DHCP working - to change all the routing/effects/mixing of the card. Firmware update through the web interface too. Plugged quickly a microphone, worked with Ardour. http://achromatopsie.fr/list/qjackctl.jpg http://achromatopsie.fr/list/routing.jpg This is a really good idea to put all the controls on the card, with a web browser, this make this card «agnostic» from the OS Can not believe this from MOTU...hope others major brands will follow this idea. Did not really test all the settings - 96000 was the setting of the card from the owner - for latency, optical input/output (do not own any device for that) etc aplay -l **** Liste des Périphériques Matériels PLAYBACK **** carte 0: AVB [UltraLite AVB], périphérique 0: USB Audio [USB Audio] Sous-périphériques: 0/1 Sous-périphérique #0: subdevice #0 cat /proc/asound/cards 0 [AVB ]: USB-Audio - UltraLite AVB MOTU UltraLite AVB at usb-0000:00:1a.7-5, high speed cat /proc/asound/card0/stream0 MOTU UltraLite AVB at usb-0000:00:1a.7-5, high speed : USB Audio Playback: Status: Running Interface = 1 Altset = 1 Packet Size = 1080 Momentary freq = 95996 Hz (0xb.ffdc) Feedback Format = 16.16 Interface 1 Altset 1 Format: S24_3LE Channels: 24 Endpoint: 9 OUT (ASYNC) Rates: 44100, 48000, 88200, 96000, 176400, 192000 Data packet interval: 125 us Capture: Status: Running Interface = 2 Altset = 1 Packet Size = 1080 Momentary freq = 96000 Hz (0xc.0000) Interface 2 Altset 1 Format: S24_3LE Channels: 24 Endpoint: 7 IN (ASYNC) Rates: 44100, 48000, 88200, 96000, 176400, 192000 Data packet interval: 125 us lsusb -v : Bus 009 Device 002: ID 07fd:0005 Mark of the Unicorn Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 239 Miscellaneous Device bDeviceSubClass 2 ? bDeviceProtocol 1 Interface Association bMaxPacketSize0 64 idVendor 0x07fd Mark of the Unicorn idProduct 0x0005 bcdDevice 1.05 iManufacturer 1 iProduct 2 iSerial 3 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 340 bNumInterfaces 6 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x40 (Missing must-be-set bit!)
