There is one message that appears in syslog, but it is always displayed when I test with aplay, unregarding the kernel version. It shows both with the working kernel (3.2) and with the problematic one (3.16). --> with kernel 3.2.0-4-686-pae /var/log/syslog ... kernel: [ 2829.369380] 2:1:1: cannot get freq at ep 0x2 ... --> with kernel 3.16-0.bpo.2-686-pae /var/log/syslog ... kernel: [ 199.353227] usb 2-1: 1:1: cannot get freq at ep 0x2 ...
