Hm. I have never experienced this kind of issue. For my information, please show your OHCI 1394 host controller? Typically, 'lspci' is good for this purpose. For your information, I wrote 'hinawa-dg00x-cui' for this series of units. It's in my repository in github.com: https://github.com/takaswie/hinawa-utils If you install libhinawa, gir1.2-hinawa-1.0, Python3 and PyGobject, the command allows you to control your unit somewhat. For example, when you change the mode of optical digital input interface, please run: $ ./hinawa-dg00x-cui 1 optical-interface set ADAT You can see all of sub-commands: $ ./hinawa-dg00x-cui 1 And see parameters for each sub-commands just by run with the sub-command: $ ./hinawa-dg00x 1 optical-interface ALSA digi00x module still has several issues, but I think you have no interests in it and don't address to it.
