Greetings again,
a nice person told me that posting the output of 'lsusb -v' would
increase my chances of being helped considerably, so I'll just do
that.
I removed the USB Hubs, only the sound card remains, no other
devices are connected.
Please tell me if you need any more information.
Best regards,
mfg
