I have a 2012 MacBook Air (macOS Catalina 10.15.7) and US-366 (FW v1.03). The US-366 works without issue when connected to a Windows 10 computer and the US-336 was previously working with the MacBook as well.
When I went to play music the other day, there was some sort of audio buffer issue where it was playing a 1/10th of a second of audio per second (think if frame-by-frame video had audio). I assume it was a memory leak on an audio buffer somewhere, so I rebooted the Mac. After rebooting, the USB indicator light no longer shows when it is plugged into the Mac. The device is also not listed in the Sound panel in System Settings.
I have tried uninstalling and reinstalling the drivers using the provided files from Tascam (v3.4.13) and updated the firmware via my Windows 10 machine.
The device is connecting at the OS level as it shows when checking lsusb:

From what I know, I did not install any new updates between it working and not working.
I don't have another Mac handy to test with, but I would imagine it would work, seeing as I've isolated away from hardware with Windows. I'm trying to avoid having to reinstall the OS if possible as I have licensed software on it that I no longer have access to keys for.
I also called Tascam support and they were unsure of anything else to try before an OS reinstall.
Let me know if anymore information is needed.
