tranzport device does'nt work as nonroot user

Installation & Configuration Linux
#1

I followed the manual and got tranzport working as root (with some limitations as described in my comment on pauls story)

But as I use ardour as a nonroot user tranzport isn’t working:

As I activate tranzport in the Options Menue the Transceiver LED is on, but Tranzport doesn’s connect.

Here’s the console output of ardour:

ardour@daw ~ $ ardour2

And here is the Errormessage in Ardours Log:

[ERROR]: control protocol name “Tranzport” could not be initialized

And here is lsusb output:

Any ideas, what did I wrong?

this is covered in the manual.

Sorry Paul, but I’ve done this already… -

/etc/hotplug/usb/tranzport exists and was set runable.
/etc/hotplug/usb.usermap exists and has the tranzport settings like described in the manual.
udev is running, and hotplug also.
But it doesn’t work on my setup. Where can I look, how can I test? Is there a debug mode of ardour, where I can get more informations, what is going wrong?

Thanks for your patience :slight_smile:
