Topic: Fireface 400 suddenly not recognized

Hello
I have a Fireface 400 and suddenly, it is not recognized by my macbook pro.

I have checked the cable with another device and it is not the cable. I have checked with another macbook pro and it is not recognized ether.

Nothing seems to be wrong. Just the " Host " light staying red. 

Anybody has an idea ?

All the best

Adrien

Re: Fireface 400 suddenly not recognized

What macOS version do you use ?
How is the cabling ? Through FW or Thunderbolt with FW adapter ?
Was there perhaps a macOS update last recently ?

Hello

10.14.6 mojave

Thunderbolt to firewire 800 adapter

Firewire 400 to Firewire 800 cable

The strange thing is that it used to work fine with this computer/os version / cable. And one day it stoped being recognized.

No updates made.

I have the feeling that it is not broken and that it is something that i do not understand

Could be that your device is defective.

Re: Fireface 400 suddenly not recognized

i have the same problem too. I have been using the rme ff400 for 18 years without problems! Now I use mac big sur 11.6 and until last week everything was working. Suddenly it stopped working and the red host light stays on all the time. I'm going crazy! Did you find out anything? Thank you
