[Alsa-user] USB-2 hub and snd-usb-audio

[Dick M. <gm...@li...>]

I've got a D-Link DUB-H4 USB-2 hub - when I connect usb sound cards to 
it they don't work, although they do work if connected directly to 
computer or via a USB-1 hub.  This error is reported:


ALSA /usr/src/alsa-driver-1.0.8/usb/usbaudio.c:804: cannot submit 
datapipe for urb 0, err = -38


What does this mean?
