Hey hey,
I haven several MIDI devices plugged in either directly as USB MIDI devices or 
using a USB-MIDI cable. They ae plugged into hubs, if that is important.

Now when I connect them through the ALSA seq API, I sometimes get 
notifications lilke these, printed on every console, if I change:
[1354175.824801] usb 1-4.1: urb status -32
The ID in brackets changes.

Any idea what this is and how it can be fixed? I have seen that this is some 
kind of general USB kernel warning, but haven't been able to find a solution, 

Thanks for any help and best wishes,
