I just found out that dmesg prints
[57372.087388] usb 1-1.1: clock source 1 is not valid, cannot use
when connecting the interface via usb to my computer, and a second
[57439.743840] usb 1-1.1: clock source 1 is not valid, cannot use
when I try to start jackd the first time (which causes the same error as
and the seconds attempt works without further dmesg lines.
There are various bug reports for "clock source N is not valid" findable
on line, but I haven't found the time to check them yet.
