The device's firmware does not allow reading this mixer control for some reason; this is probably a bug.
Please try the following commands: rmmod snd-usb-audio modprobe snd-usb-audio ignore_ctl_error=1
This makes the driver ignore errors, but cannot prevent the errors from happening in the first place. Please check if you get the desired effect when you write this control.
