Maybe the problem of bandwidht is the same as the one describe in

So it is maybe required unbind the HID interfaces?
But i am no at all an expert in USB

So I think that usb sound driver asks for a too high bandwidth that is not
compatible with USB2 protocol. But because it works on windows on USB2, it
should not be the case.
How can I know that the value of bandwidth that is asked?
Thanks,
M8hpw

Clement you are right, I try on a usb 2 port instead of a usb 3 one, an this
error is removed.But the usb 32 channel sound card is not really recognized.
But now I have a new error :usb 4.1.1: cannot submit urb0 : error -28 : not
enought bandwidth.
But the device works under Windows 7 with the same USB 2.0 port.
Regards.

This looks like a bug in the host controller driver.
Can you change to a different port (USB2/USB3)?
