I'm using a Behringer UMC22 with my RPi3B+. Works out-of-the-box.
And I’m using a Cambridge Audio Dac Magic 100 which in fact works better out of the box in LE than it does in most other Linux distros as it recognises both USB modes, USB 1 (48khz) and USB2 (192khz).
Again these different modes are selectable via a switch on the DAC but other distros seem to ignore this and default to USB 1 no matter what you try.
Appears to be a Pulse Audio issue in most cases although I haven’t as of yet tried its supposed successor PipeWire in Ubuntu to see if anything has changed on that front.
I’m happy enough that the Bose Companion 5 is now working albeit a little unpredictable with LE11. I always thought that the USB feature as supplied by Bose was an afterthought at the time.
Of course Bose always suggested at the time that you connect analog via the Bose controller if you were experiencing difficulties with USB.
