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.
Julien

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