I have multiple raspberry PI 4Bs with openSUSE Leap 15.3 and some with raspbian
9. I got a USB speaker (e2b7:0811) which I connected to the 4Bs using Leap
15.3.
This speaker works fine when I plug it in when the PI is already running:

However, after a reboot with the device still connected (no change) the kernel
boots and does not even see the device.

I have tried the same USB speaker on another PI4B with Leap 15.3 with the same
result. So, it doesn't seem to be that PI.
When I connect the speaker to a PI3 with raspbian 9, it works as expected.

I noticed that the raspbian uses dwc_otg vs. xhci_hcd on Leap. However, dwc_otg
doesn't seem to be a separate module in raspbian nor it is available on leap.
As the speaker is working when I un-plug and plug it in again, I wonder what
may causes this strange behavior. Especially as I do not see the device via
lsusb after reboot, though it is still connected.
Any ideas on how to fix it?
