    initial v1  
    1 May I add something to this issue?
    2 
    3 I have this USB audio device in the form of a USB to RCA adapter, and it doesn't work with Haiku. It does work correctly with other OSes on this system, however.
    4 
    5 Before reporting this I've done a system update and it's currently hrev58622.
    6 
    7 The only relevant information in the syslog is this line.
    8 {{{
    9 KERN: loaded driver /boot/system/add-ons/kernel/drivers/dev/audio/hmulti/usb_audio
    10 }}}
    11 
    12 Here's the `listdev -v` output of this device, as well as the hub/controller it's connected to. I'm currently connecting it to a native USB 2.0 (EHCI) port on the motherboard.

    264 The device reports USB 2.0 but it's actually an ADC 1.0 device (Audio codec version .. 1.0), similar to what has been discussed here: https://discuss.haiku-os.org/t/haiku-cannot-find-any-audio-device/16286/11
    265 
    266 Considering there's only a single line relevant to `usb_audio` I suspect the driver has not picked up this device because of its reporting itself as USB 2.0.
