The snd-usb-audio module apparently did work for US= B1 mode, but caused the MIDI port to be unavailable. And, yes, its parent commit tested good (473d5ae82d73c3b21160b725af0e247fa94d7832), and this really was tested as b= ad: d763145312582c08c4e9ed99d61276cde8488256 is the first bad commit commit d763145312582c08c4e9ed99d61276cde8488256 Author: Takashi Iwai Date: Thu Apr 8 09:56:56 2021 +0200 ALSA: usb-audio: Skip probe of UA-101 devices UA-101 device and co are supported by another driver, snd-ua101, but the USB audio class driver (snd-usb-audio) catches all and this resulted in the lack of functionality like missing MIDI devices. This patch introduces a sort of deny-listing for those devices to just return -ENODEV at probe in snd-usb-audio driver, so that it falls back to the probe by snd-ua101.
