This guy seemed confident he had the issue resolved but didn't mention what model RPI he was using. Both the RPI3b+ and the Bose Companion 5 are USB2.00 devices. This really is a curious one. https://forums.raspberrypi.com/viewtopic.php?t=15872
The guy mentioned a quirks file for the kernel. If that file is missing, your quirk alias has no effect.
I suggest to try the same on Raspberry Pi OS. Maybe LE doesn't have that quirks file.
