USB 2.0 Compliant Device - No longer working after Ventura - M1 - Digigram 442

My USB audio interface will show up in System Information but not Sound in System Setting and not Audio / MIDI devices.

It worked on M1 in Monterey just fine, still mounts on all pre Ventura Machines I've tested it on and one Windows 11 VM.

So far I've

Spoken with Apple and Digigram each are point to the other to fix it. multiple times.

Checked Privacy and Security, Allow devices to connect.

Tried looking for generic drivers.

Tried looking for some kind of power limiting on the USB out (the device is bus powered)

Placed legacy .kext USB / USBAudio drivers in Extensions

Looked for conflicting extensions.

Started looking into building my own driver.

Something with USBAudio has clearly broke with the move to Ventura, and It pretty bad to be told just use a new interface, especially when there really isn't another interface that will do what this one dose, another 1600 bucks to get 2 of something else that will provide the same I/O, shouldn't be the answer.

Can confirm plugging the interface into more machines the following.

M1 - Big Sur - functions properly.

M1 - Monterey - functions properly.

I7 - Ventura - functions properly.

I7 - Monterey - functions properly.

M2 - Ventura - dose not work.

M1 - Sonoma - dose not work.

This seems isolated to only Apple silicon machines running Ventura or later.


Please patch this Apple!

if it was me then I would if I knew someone else with m1 mac try to test it with that, if it's a general issue with all m1 computers and not just yours then digigram would be able to reproduce it and would likely be working on a new driver and just throwing the ball over in apples couth to save some time.

if venture introduced something which makes digigrams driver or firm ware not work anymore then it's not likely it will be able to change it back to make their digigrams product work, it's the third party manufactures to be compliant with a platform really
