I tried updating my Fedora 34 kernel from-
and it no longer recognises my XMOS USB device:
$ cat /proc/asound/cards
0 [ALSA ]: bcm2835_alsa - bcm2835 ALSA
1 [vc4hdmi0 ]: vc4-hdmi - vc4-hdmi-0
2 [vc4hdmi1 ]: vc4-hdmi - vc4-hdmi-1
4 [H20 ]: USB-Audio - HU300 HiFi 2.0
Yunyue Audio HU300 HiFi 2.0 at usb-0000:01:00.0-1.3, high speed
So, device number 4 is missing with the 5.12.14-300 kernel.
Given that the rpi4 is not yet supported, whom should I tell about this apparent bug, please?
What's a "XMOS USB hardware"? I doubt being USB it's specific to the
RPi4, does it work on another devices such as an x86 device? Can you
give more information about the device, what driver does it use when
it worked, what's the output of the lsusb line for it etc.
Thanks, for replying, Peter.
It is the sound card #4 mentioned above, labelled H20. It is a USB to
I2S audio interface to an ES9038 DAC.
I can try it with an x86_64 PC when a new card arrives at some point in
I don't know what you mean by that.
lsusb says it is this:-
Bus 001 Device 003: ID 20b1:0008 XMOS Ltd HU300 HiFi 2.0
It uses the snd_usb_audio driver, according to lsmod.
Should I just report it on Bugzilla, saying that it is
Do other USB devices work in the RPi?
Was this an upgrade from and older Fedora release at some point in the
past? If so does running rpi-uboot-update and rebooting fix it?
It was a fresh F34 installation some months ago, but with minimal updates.
Last week updated just the kernel and my usb audio card was not recognised.
As asked above do other USB devices still work?
Yesterday, I updated everything, with the same results.
Did you run rpi-uboot-update?
Oops, sorry; yes, other USB devices work, e.g. USB 3.0 disk, plugged
into USB 3 socket. The XMOS USB audio device is in a USB 2 socket.
I did not run rpi-uboot-update, because it was not an upgrade from an
older release ...
... and yes, the rpi-uboot-update fixes it! Hoorah. Many thanks, Peter. :)
Why did the rpi-uboot-update make a USB device reappear? I thought dnf
updates did all that sort of thing nowadays.
Is there some documentation somwhere for rpi-uboot-update, please?
